When purchasing a new laptop or building a computer, the processor is the most important decision. But there's a lot of jargon, especially the cores. For example, do you need a dual-core processor, a quad-core, a hexacore, an octa-core, or more? Let's cut the jargon and understand what it all really means. Dual-Core vs. Quad-Core, Explained Here's everything you need to know There is always only one processor chip. That chip can have one, two, four, six, eight, ten, twelve, or even sixteen cores. So if you find a "single core" CPU, that means the processor chip has one core. And a dual-core processor has two cores, a quad-core has four, a hexa-core has six, an octa-core has eight, and so on. Currently, an 18-core processor is the best you can get in consumer PCs. I mean, you could buy a 64-core AMD Threadripper, which is available to consumers, but that's more processing power than most regular consumers could think of using. Each "core" is the part of the chip that does the processing work. Essentially, each core is a central processing unit CPU. This article deals with dual-core vs. quad-core processors for computers, not for smartphones. We have a separate post on understanding smartphone cores. The Difference Between Dual-Core and Quad-Core CPUs You might think more cores will make your processor faster overall, but that's not always the case. It's a little more complicated than that. More cores are faster only if a program can split its tasks between the cores. Not all programs are developed to split tasks between cores. More on this later. Each core's clock speed is also a crucial factor in speed, as is the architecture. A newer dual-core CPU with a higher clock speed will often outperform an older quad-core CPU with a lower clock speed. Power Consumption More cores also lead to higher power consumption by the processor. When the processor is switched on, it supplies power to all the cores, not just one at a time. Chip makers have been trying to reduce power consumption and make processors more energy efficient. But as a general rule of thumb, a quad-core processor will draw more power from your laptop and thus make it run out of battery faster. More Cores Equal More Heat More factors than the core affect the heat generated by a processor. But again, as a general rule, more cores lead to more heat. Due to this additional heat, manufacturers need to add better heat sinks or other cooling solutions. Are Quad-Core CPUs More Expensive Than Dual-Core? More cores isn't always a higher price. Like we said earlier, clock speed, architecture versions, and other considerations come into play. But if all other factors are the same, then more cores will fetch a higher price. Software Optimization for CPU Cores Here's the dirty little secret that chip manufacturers don't want you to know. It's not always about how many cores you are running; it's about what software you are running on them. Programs have to be specifically developed to take advantage of multiple processors. In the past, "multi-threaded software" wasn't as common, although as it's near-impossible to buy a single-core CPU these days, this issue isn't once what it was. However, it's important to note that even if it's a multi-threaded program, it's also about what it is used for. For example, the Google Chrome web browser supports multiple processes, as does video editing software Adobe Premiere Pro. Adobe Premiere Pro instructs different cores to work on different aspects of your edit. Considering the many layers involved in video editing, this makes sense, as each core can work on a separate task. Similarly, Google Chrome instructs different cores to work on different tabs. But herein lies the problem. Once you open a web page in a tab, it is usually static after that. There is no further processing work needed; the rest of the work is about storing the page in the RAM. This means even though the core can be used for a background tab, it is unnecessary. This Google Chrome example is an illustration of how even multi-threaded software might not give you much of a real-world performance boost. Double the Cores Is Not Double the Speed So let's say you have the right software and all your other hardware is the same. Would a quad-core processor then be twice as fast as a dual-core processor? Nope. Increasing cores does not address the software problem of scaling. Scaling to cores is the theoretical ability of any software to assign the right tasks to the right cores, so each core is computing at its optimal speed. That's not what happens in reality. In reality, tasks are split sequentially which most multi-threaded software does or randomly. For example, let's say you have a quad-core processor Core1, Core2, Core3, Core4. You need to accomplish three tasks T1, T2, T3 to finish an action, and you have five actions A1, A2, A3, A4, A5 like this. Here's how the software will divide tasks Core1 = A1T1 Core2 = A1T2 Core3 = A1T3 Core4 = A2T1 The software is not smart, though. If A1T3 is the hardest and longest task, the software should have split A1T3 between Core3 and Core4. But now, even after Core1 and Core2 finish their tasks, they have to wait for the slower Core3's task to complete the action. All of this is a roundabout way of saying that not all software is optimized to take full advantage of multiple cores. And doubling the cores does not always equal doubling the speeds. Where Do More Cores Really Help? Now that you know what cores do and their restrictions in boosting performance, you must be asking yourself, "Do I need more cores?" Well, it depends on what you plan to do with them. Dual-Core and Quad-Core in Gaming If you fancy yourself to be a gamer, then get more cores on a gaming PC. The vast majority of new AAA titles popular games from big studios support multi-threaded architecture. Video games are still largely dependent on the graphics card to look good, but a multi-core processor helps too. Editing Videos or Audio For any professional who works with video or audio programs, more cores will be beneficial. Most of the popular audio and video editing tools take advantage of multi-threaded processing. Photoshop and Design If you're a designer, a higher clock speed and more processor cache will increase speeds better than more cores. Even the most popular design software, Adobe Photoshop, largely supports single-threaded or lightly threaded processes. Multiple cores aren't going to be a significant boost with this. Should You Get More Cores? Overall, a quad-core processor is going to perform faster than a dual-core processor for general computing. Each program you open will work on its own core, so if the tasks are shared, the speeds are better. If you use a lot of programs simultaneously, switch between them often, and assign them their own tasks, then get a processor with more cores. Just know this overall system performance is one area where far too many factors come into play. Don't expect a magical boost by changing one component like the processor. Choose wisely and buy the right processor for your needs.

What types of CPU should you buy? There are a few different options out there and when you buy a central processing unit, it can be hard to know just what you really need in terms of speed, core, costs, brands, and more. It is complicated and it isn’t something we talk about all that often. Still, a CPU is known as the “brain of the computer,” which means that it is actually one of the most important things. A good CPU helps with multitasking, performance, and speed above all else, but it helps overall efficiency in a million little ways. In this guide, our experts will break down the different central processing unit types and help you understand where you should look, what you should look for, and how you can use each one. Keep reading for more. ContentsWhat Is a CPU?Different Types of CPU Explained– Single-Core CPU– Dual-Core CPU– Quad-Core CPU– Hexa-Core Processor– Octa-Core Processor– Deca-Core ProcessorAMD vs Intel Processors– AMD CPUs– Intel CPUs– ARM CPUsCan a Computer Function Without a CPU?In Conclusion What Is a CPU? CPU is the shortened and more commonly used form of central processing unit or processor. The “unit” is composed of two parts the central processor and the electronic circuitry that is located within the tower of your computer. The CPU is a multitasking device that feeds the computer information, performs logic and arithmetic for programs, and inputs and outputs operations. It is one of the core elements of the computer but up until recently, there hasn’t been much discussion on them amongst the general public. CPUs now have microprocessors that use integrated circuits that have a unit metal-oxide-semiconductor. This chip has the CPU as well as memory chips, microcontrollers, interfaces, and other systems. This chip takes up a single socket as a “CPU core.” Different Types of CPU Explained Your CPU is one of the most important elements of your computer, managing almost all of the commands and calculations that make it work properly. It controls components, peripherals, and important processes no matter what you do. A CPU needs to rapidly input and output information. The different components all need to be powerful enough to work together everything will perform to the capabilities of the slowest, weakest part. It is important to know that there are two leading manufacturers of CPU processors AMD and Intel. There are other manufacturers, but these are the most prolific. When we talk about the type of central processing unit, we need to think about not only the number of cores, but the brand, size, speed, and more. However, the most defining component is the number of cores, so that is how we classify the different types of CPUs. – Single-Core CPU The original type of CPU was a single-core CPU. It is available widely and used in most standard personal computers and business computers. These CPUs can only execute one command at a time, making them poor options for multitasking. If you are trying to do more than one thing at a time, it is possible, but you will notice a degradation in performance. If one operation starts, the next process will have to wait in a virtual queue of sorts until the first one finishes. The computer doesn’t like when these queues form and it could start to freeze and take a long time to perform operations that normally take just a few seconds. If possible, we don’t recommend this type of CPU at all unless someone just needs a computer for bare-bones activities like word processing or social media browsing. – Dual-Core CPU A dual core CPU consists of two cores that act like one CPU. This means that the CPU can multitask more effectively and allows two things to happen at once, or more. Once again, you can overload a dual-core CPU, but it is harder to do. To most effectively use a dual-core CPU, both the programs and the operating system need to have a unique code in them called a “simultaneous multi-threading technology” code. This is something found standard in most operating systems and programs today, but there are a few exceptions. Most computers today will have at least a dual-core CPU, even the ones you buy without customization. Even this number of cores is becoming outdated and limits future-proofing capabilities in your build. – Quad-Core CPU A quad-core CPU has four cores on a single CPU processor. It is a refined model that is used in the best computer builds today, especially in some of the best all-in-one computers and boxed computers. The CPU evenly divides the workload between the cores, making it the best option for multitasking. It doesn’t signify single operations, making it faster, lighter, and more efficient than the other cores. Just like with the dual-core CPU, quad-core CPUs use the SMT code to speed up the processes and make them seem instantaneous in many cases. For some people, a quad-core CPU will be overkill. However, gamers, programmers, and anyone who heavily uses the computer while streaming, playing music, editing, or using bulky programs would benefit from this CPU size. – Hexa-Core Processor Even bigger and faster than a quad-core CPU is the Hexa-core processor. This comes with six cores and can execute tasks faster than other models. This processor is limited and harder to find on personal computers than one would expect. Hexa-core processors are most commonly used in smartphones and tablets. Most smartphones including those from Android and Apple will use a hexacore processor. These processors make it possible to play games, listen to music, text, and get notifications all at the same time. – Octa-Core Processor Even rarer is the octa-core processor that has eight independent cores to go even faster. These processors are a bit more expensive and only necessary for people who need to work quickly for their jobs. Gamers can use an octa-core processor, but only professional gamers who play for money will really get the advantages out of it. There are core sets in this build that are typically tasked to do the repetitive, minimum powered activities that we do on a computer and then there are cores set aside for faster processing and action. With some software and builds, you can actually pick these programs, but that is a far more advanced level of computer building. – Deca-Core Processor A deca-core processor can come as a double core processor, four cores with quad cores, six cores, and more. Deca-core uses ten independent cores as well, though those are the most expensive and hardest to find options. These systems function just like the octa-core processors do, with some cores dedicated to mundane tasks while others perform the more advanced tasks. Newer smartphones and tablets are being manufactured with deca-core processors and modern manufacturing has made them lower in cost than other cores. For the foreseeable future at least, deca-cores are going to be future-proofed. Most new market items will have the deca-core processor as well, even budget or low-priced computers because of how much easier and cheaper the manufacturing process is. AMD vs Intel Processors When we talk about computer processors types, we talk about AMD and Intel for the most part. These manufacturers are both great, though they tend to be used in different situations. While they can be, and are, used in other builds, they tend to work best in these categories. – AMD CPUs AMD CPUs are most often used in servers and workstation computers for bigger corporations. They can be used in gaming computers as well, but that isn’t as common. The most common examples of CPU from AMD are K6-2 K6-III Athlon Duron Athlon XP Sempron Athlon 64 Mobile Athlon 64 Athlon XP-M Athlon 64 FX Turion 64 Athlon 64 X2 Turion 64 X2 Phenom FX Phenom X4 Phenom X3 Athlon 6-series Athlon 4-series Athlon X2 Phenom II Athlon II E2 series A4 series A6 series A8 series A10 series AMD doesn’t produce as many CPUs as Intel, but their CPUs tend to be the ones that push manufacturing forward. They use the latest technology in their builds. Their CPUs are generally more expensive but have incredible longevity. – Intel CPUs Intel CPUs are used most frequently in PC builds and smaller companies. The most common and well known Intel CPUs are 4004 8080 8086 8087 8088 80286 286 80386 386 80486 486 Pentium Pentium w/ MMX Pentium Pro Pentium II Celeron Pentium III Pentium M Celeron M Pentium 4 Mobile Pentium 4-M Pentium D Pentium Extreme Edition Core Duo Core 2 Duo Core i3 Core i5 Core i7 Core i9 For a long time, Intel was known as the “gold standard” for all CPUs, so it has a deeper base of CPUs. They have slowed down production in the last few years, however. Intel has created some great processors that have changed the game, but they have also had some clunkers. – ARM CPUs One manufacturer we don’t talk about all that often is ARM CPUs, even though they may make more CPUs than any other company. These CPUs are used in tablets, smartwatches, and smartphones because they are smaller and require less power. In turn, they are cheaper and generate less heat. Can a Computer Function Without a CPU? A computer cannot function without a CPU because it helps with the transmission of data. It can function with a bad CPU, but it is a difficult experience. You want to ensure that your CPU is compatible with everything else in your computer, in particular your motherboard. In Conclusion In general, the bigger your CPU is, the better it will be. By “bigger,” we mean that the more cores it has, the better it will perform and the faster it will be. If you are currently using a computer with a certain number of cores and you find that it freezes, slows down, or just performs strangely, that is a sign that you need more cores. In general, people need more cores and a better type of CPU if they do things like video editing, gaming, streaming, and more. There are budget-friendly options out there, so don’t always take money as the gauge for whether or not a CPU is a good match. If you aren’t experiencing any problems with your computer, or you don’t do any of the things listed above, you can buy a more basic CPU and spend your money elsewhere.

Contents What Is a CPU Core?What Do Cores Do in a CPU?How Do More Cores Affect Performance on Windows 10?So, More Is Better? The Central Processing Unit CPU of a computer’s most important component. It’s essentially the brain that makes calculations and decisions about how to run every task and operation on a PC. The CPU is integral to a PC. For example, you can still use the computer without a dedicated video card, a network card, or even a sound card. However, without the processor, you merely have an expensive piece of industrial brick. There are various ways to categorize the CPU—by manufacturer, generation, or clock speed among others. However, the most important method of classification is by how many cores they have. Using that yardstick, there are two main CPU types the single-core CPU and the multi-core CPU. Single-core processors are all but extinct at this time so we only have computers whose processors use between two and eight cores. However, does it matter how many cores a processor has and how many your CPU needs? This article answers these questions. We’ll explain each type of CPU and how your choice of processor correlates to performance. What Is a CPU Core? A CPU is a computer’s processor chip that executes instructions fed to it by a computer program. On a Windows 10 PC, that program is the operating system. The main component of a CPU is the processing unit or core. The core is responsible for reading and executing program instructions. If the processor is like the human brain, then the processing unit or core is like the cerebrum. It’s the part that carries out the primary functions of the CPU. Now, just like the human cerebrum is divided into right and left portions, a CPU can have more than one processing unit. The more cores there are, the faster the tasks are carried out. A computer with one processor core can carry out a single task at a time. Although it may perform the task very fast it must finish before it can do something else. On the other hand, multiple cores help speed up system operations because the computer treats each core as a different processor. It assigns tasks to each one simultaneously. With multiple tasks being done at the same time, both speed and performance are increased. In the early days of the computing system, processors only had one core because of the limits of technology at that time. Nowadays, a single-core CPU is a rare thing; every consumer PC comes with at least a two-core processor. What Do Cores Do in a CPU? When it’s time to purchase a new computer, many users are confused about labels like “dual-core”, “quad-core,” and so on. They might wonder what cores do exactly and why the number of cores matters. Strictly speaking, a core is equivalent to a CPU. Most modern computers have multiple cores on a processor chip. In effect, the system has more than one CPU to use at a time. The operating system distributes tasks among the cores to ensure the smooth running of computer programs. Depending on what you wish to do with your system, you probably need one with multiple cores. How Do More Cores Affect Performance on Windows 10? Sure, you might not mind splurging on the latest and greatest PC if you have the money. However, it might be better to tailor your purchase according to your needs. The kind of PC you buy should be designed for the kind of programs you want to run on it. Also, remember that performance is not only dependent on hardware but software as well. Too many junk files on the hard drive, corrupted memory, and even invalid registry keys can make a PC with adequate specs perform far less than the sum of its parts. A PC cleanup utility like Auslogics BoostSpeed will help you restore the performance to the normal level. For basic tasks like browsing, watching videos, playing music, and using basic productivity apps like Word and Excel, a computer with two or four cores might be sufficient for your needs. For gaming and video editing, you should choose a good computer that has between four and eight cores as the increased number of cores will be better able to handle the extensive operations that gaming and graphics editing involves. For complex workstations that require graphics rendering, you’re better off splurging on one of the specialized beasts out there with at least 12 cores. You can even find up to 64 cores for the most extreme resource-demanding tasks like 3D animation rendering and on-site network computing. These are the common types of CPU based on the number of cores Single-core CPU or processor with one core. Dual-core CPU or processor with 2 cores. Quad-core CPU or processor with 4 cores. Hexa-core CPU or processor with 6 cores. Octa-core CPU or processor with 8 cores. Deca-core CPU or processor with 10 cores. Duodeca-core CPU or processor with 12 cores. Let’s look at each one in turn. Single-Core CPU The age of microprocessors began with a one-core CPU. Even though it could only perform a single operation at a time, it was still an improvement over what came before. Nowadays, the only place to easily find a processor with one core is in a tech museum. Dual-Core CPU Processor chips with two cores can be found in most entry-level computers. Examples of two-core CPUs are the Intel Core Duo and the AMD X2. They use two processors on a single chip. Dual-core computers are very budget-friendly and allow you to do a few basic tasks at a time. You can play media files and perform simple browsing, type out documents and play old Super Mario games without overloading the CPU. Quad-Core CPU A computer with four cores is good enough for regular tasks like gaming, basic video editing, and multi-productivity work. The Intel 6th and 7th generation chips are mostly quad-core. Hexa-Core CPU You can find processors with six cores in many of the latest mid-range gaming and graphics editing laptops around. If you’re looking for a machine that can handily perform advanced video editing 3D rendering, and play AAA games comfortably, you can go for a hexa-core chip. However, the PC should also be paired with at least 8GB of RAM to take full advantage of the parallel processing. Octa-Core CPU This type of chip is found in high-performance computers used by engineers, architects, and specialized workers that do a lot of complex graphics rendering. If you’re a professional gamer or a programmer that uses software that needs a lot of resources, an 8-core PC may be the best tool for your trade. Deca-Core CPU Any computer with a 10-core chip should easily handle anything you throw at it, all other things being equal. The Intel Core i9-10850K is an example of a deca-core chip produced for gaming desktops. Playing the heaviest games at 4K, virtual reality, and advanced software mapping will be a breeze with this type of processor. Duodeca-Core CPU and Above In recent times, CPUs with more and more cores are being released for the most demanding operations a computer could ever do. Examples are the AMD Ryzen 9 5900X with 12 cores, Intel Core I9-9980XE Extreme Edition with 18 cores, and AMD Ryzen Threadripper 3960X with 24 cores. These are performance monsters for deep-pocketed users looking for a specific technology. So, More Is Better? There is a pretty straightforward correlation between the number of cores on a PC and its optimum performance. But not always. Other factors that determine how fast a computer is. Apart from the number of cores, you have to consider the number of threads as well. Threading is the ability to run multiple processes on a single chip at a time. Some chip makers added threading capability to their better chips to further boost performance. So, thanks to threading capability, a quad-core computer might be able to run 8 processes at once while a hexa-core computer is limited to just six processes. In that case, the 4-core PC with threading capability is the better choice as it allows for better multitasking and enhanced performance. For the best value when shopping for a new PC, you should be on the lookout for CPUs with multithreading capability. Intel calls theirs Hyper-Threading and AMD calls theirs Simultaneous Multithreading. The CPU’s clock speed is another factor to consider. Clock speed is the rate at which the processor operates, defined as the completion of one processing cycle and measured in gigahertz. A general rule of thumb with clock speeds higher is better. Of course, the storage and RAM affect the speed of the processor as well. For the best results, you should go for a computer that pairs a good CPU with a fast SSD and at least a DDR4 memory. We hope this article has increased your knowledge of computer processors. With this, you’ll go into your next PC purchase better informed. Given that PCs with 8 cores and above aren’t exactly cheap, you may need several rounds of saving to get what you want. In the meantime, you can use the Optimize Tool in Auslogics BoostSpeed to finetune your current PC for the best performance.

An octa core or a hexa core one considering that I don't want to upgrade cpu again for atleast 5-6 years Alpha3031 Apr 9, 2015 Form Please fill. Nov 27, 2013 2,902 0 13,460 2 Form Please fill. 3 I said "if" Sep 4, 2007 6,360 476 43,990 4 If it were me the minimum core count for an intel CPU would be 6 cores if your wanting 5+ years out of it, 8 would be better. I would also plan on overclocking to squeeze more performance from my CPU over time. Ex. I got a i7 3930k 3 years ago. i initially overclocked it to January made some new OC profiles stable up to maybe but it needs more testing still to be sure. It allows me to get more from my cpu over time. Yeah i could have cranked up the core speed from the get go but i would not have seen the benefits later as it would have already felt like the norm, plus when you OC you wear things out faster so there is that to consider in the parts longevity. Sep 30, 2012 1,269 1 11,960 5 You kinda answered your own question. You'll obviously want to buy the absolute best you can afford if you want maximum longevity, and right now with x99, the choice is even more clear-cut than with previous x79 setups since with the current lineup, the top-end i7 has more cores than the model down.

That said with consoles having 8 core CPU's and multi-core/ multi-thread CPUs in PC becoming common place. In the next few years 8 cores/threads+ could well be the new gold standard. The Op was wanting something for 5+ years so it's reasonable to think two more cores will be useful in that time frame instead of just six. 12 [quotemsg=15648418,0,1935761]This thread is under PC gaming category.

The 4790k is the best gaming CPU out right now. The extreme series Haswell-e is for enthusiast builders, video editors, servers.. etc not gamers. Go with the 4790k and you should be gold for about 4-5 years. Nov 27, 2013 2,902 0 13,460 13 I'd go 5820K and custom liquid cooling. Plenty of space for 3/4 GPU setups. you'll need a full tower case too. Though it does depend on what games you play. Some games still only use one or two cores.

In fact many Mobo manufacturers warn users of this in their Mobo website/users manuals online. That is exactly why there is a 5830k with 40 PCIe lanes to handle that kind of bandwidth. Not to say the 5820k is a bad CPU but one needs to be aware of it's strengths and weaknesses before making a choice. And yes i have seen all the charts showing the "minimal" loss in frames even when dropping a GPU to PCIe 4x but if your spending the kind of money one is spending on a Extreme Series MOBO and CPU it hardly makes sense to kneecap your gaming performance even if ever so slightly for the get go. Call me crazy. Oct 19, 2007 3,226 6 21,415 15 Wait till DX12 comes out. It "might" be a game changer in terms of number of cores in a cpu. Its a rather smart move to wait and see roudups in games and other software on dx12. Sep 4, 2007 6,360 476 43,990 16 [quotemsg=15649243,0,151198]Wait till DX12 comes out.

So you could wait and if you can it might be worth it but generally speaking i buy whats available and best today...not tomorrow. The future is always uncertain and computers change at break neck pace. Though it's slowing, if you ask me, on the CPU side...sandy bridge to ivy bridge to haswell....the gains are minimal performance wise and in some cases a back step though power efficiency is much better with the newer generations. Sadly efficiency seems to be the focus not pure performance anymore. 17 I was thinking about buying the best octa core processor by this fall in time for black froday sales along wuth a dual gpu probably 980Ti which would be launched by then. Can a mid tower cabinet with asus x99-a support that?

As for the NVlink i believe that come with pascal and there are no motherboards with that slot yet on the market. So its out of reach for now. 24 So should I go for cheaper 4790k and z97 extreme then? With 970 sli as I don't do anything else other than gaming. That should last me 4 or 5 years maybe. Jan 9, 2015 1,072 0 19,660 25 Honestly we have the 2 most exciting games in the last few years, coming next 2 month. This fact already worth to build a PC to play them on ultra. I think you shoudln'T worry about beeing future proof for 5-6 years, because it is impossible to do so. If you understand the Moore law in electronics, you'll already know why. Both Intel and nvidia's new architectures are in the gate. And actually if you own an expensive PC you can sell it whenever you want and rebuild from scratch. Especially with active warranty on the parts. The main decision you should make if you want to play in 4k or 1080p. - For 1080p a z97,i7 4790k and a single gtx 980 is the best choice. it maxes all games with 60fps+. Then when new architectures hit, you sell rebuild, simple as that. - For 4k gaming x99, i7 5930k, single or sli titan-x is the only smart choice. Note that people will tell things like 970 sli and 980 sli is good enough for 4k or 1440p, but they are wrong in both cases. The reason for this is the texture size that modern games use. the 970 is not even a choice for 1440p because of 3,5gb vram limitation. most of modern games are optimized to run on ultra on a 4gb card on 1080p resolution. With the titan-x and the 6core you would be a bit more future proof, but it's still not worth to wait the warranty to end, so you are in the same boat. For now, i'd advice to go 1080p and z97, single 980 with i7 4790 or 4790k, except if you have tons of disposable cash and you really want to go 4k now.

The smartphone market becomes more competitive each year with manufacturers attempting to outdo each other on power, speed and battery life. More and more phones have octa-core processors, but are they better than quad-core and dual-core phones? We explain what you need to know about smartphone processor arms race between AMD and Intel has been hotting up since the early 2000s with the releases of the Athlon 64 and Intel’s Core 2 Duo back in 2005 and 2006 the years have gone by we’ve seen progression in not only the speed of each core, but the amount of cores on each physical chip. The latest high-end consumer processors contain up to 8 cores, although they are still much more powerful than those found in vs quad-core vs dual-core Smartphone processorsIn smartphones we’ve seen a similar progression, with quite a few phones boasting octa-core chips. Smartphones have rapidly caught up to computer processors with their core count, but why has this happened so quickly?The answer, in short, is a demand for better battery phones use ARM processors, and while it is – relatively speaking – fairly easy to put a powerful quad-core processor in the latest phone, battery technology isn’t really up to the job of keeping that processor along with the screen, modem, GPS and other components fed with power all day also Qualcomm Snapdragon 845 specs and featuresSo ARM developed what is effectively a dual quad-core processor a single chip with two sets of four cores able to share the same cache memory. It calls this set of cores can deliver high performance when required at the expense of high power drain, and the other set delivers a lower level of performance but also requires much less battery power. Usually, only one set of cores is used at one time, so for all practical purposes it’s really a quad-core low power’ cores are used for most of the time, including for tasks such as reading and sending email, navigating around the operating system, and also browsing the web. But when more power is needed, such as for intensive games or editing photos or video, the chip dynamically switches to the faster quartet of far, the only octa-core processors we’ve seen have been in Android phones, from manufacturers including Qualcomm, Samsung, MediaTek and a long time, Apple stuck with dual-core processors in the iPhone, and it was only in the iPhone 7 that it made the move to quad-core. But as with octa-core processors, the A10 Fusion chip actually uses a pair of dual-core chips, one high-performance pair and one energy efficient approach doesn’t always mean there are equal numbers of high- and low-performance cores. Some phones have hexa-core processors, which typically employ a pair of powerful cores, and four power-efficient cores. There are even octa-core chips which have eight low-power cores, such as the Qualcomm Snapdragon vs quad-core vs dual-core PerformanceCompare benchmarks, as you can in our smartphone charts, and you’ll see that an octa-core processor is not twice as fast as a quad-core. And given what you now know about the design of the chips, you wouldn’t expect them to the same with the iPhone 7 it’s not twice as quick as the iPhone 6s. The fact it’s 40 percent or so quicker is impressive, but that’s mainly down to the improvements made in the high-performance pair of cores, not because there are twice as many of particularly impressive is the way that iPhones have beaten or matched the best Android phones with – often – half as many forget that the main processor isn’t responsible for graphics performance. To a large extent this is down to the GPU – graphics processing unit. This is the biggest factor in determining how well games run on a phone, but the screen resolution must also be taken into account. You can see in this diagram that the CPU is only one of many components on a modern smartphone processor, which is called a SoC main point here is that a phone with an octa-core processor isn’t necessarily going to be a better choice for playing games. It may not even be a better choice for CPU-intensive apps, and this is why it’s important to read reviews and look at benchmark results if this kind of performance is important to you when choosing a course, we’re talking about processors and performance at a very high level here. Overall performance includes many more factors such as the size and speed of the on-board cache, the amount and type of RAM and the software being used. The latter is especially important, since apps need to be written to use all the available processing cores. This is all beyond the scope of this article, however. Suffice to say that Android – and iOS – are optimised for multi-core processors as are modern vs quad-core vs dual-core which is best?So let’s get to the main question. Is it best to buy a phone with the most cores you can get? Not have tested the performance of many, many phones, and there is no evidence that more cores equals better performance. As we said above, the extra cores are often there for efficiency and simply knowing the number of cores tells you nothing about the architecture of the CPU and how many of those cores are high it doesn’t really make sense to buy a phone based on its core count, just as you wouldn’t buy a car purely because of the number of cylinders in its engine there’s far, far more to if you are looking for a phone upgrade, be sure to check our round-up of the best phones to buy.

The current processors in the market have 2 to 24 cores inside of them, each capable of handling an individual data thread. this enables the processor to perform a task Whether you use a modern computer or a smartphone, your device likely has a processor with multiple cores. The processor is the brain of the device which performs the tasks instructed by the various software. With evolving technology, tiny processors are becoming smaller in size and better in terms of performance. Not only that, but they now include more and more processing cores. The most modern processors now have up to 24 physical cores that are publically available, whereas according to rumors, AMD is currently working on processors having 256 cores each! If you are confused about the difference between a processor and a core, or having trouble selecting a processor for your new build and cannot decide how many cores it ought to have, then this is the article for you. Let us dig into the details of the different types of processor cores and their differences. Table of contents What is a Processor What is a Processor Core What is a Multi-Core Processor Hexadeca Core Processor Tetradeca Core Processor Dodeca Core Processor Deca Core Processor Octa Core Processor Hexa Core Processor Quad Core Processor Dual Core Processor Multi-Core Processor Considerations Type of Work Power Consumption Heat Dissipation Multitasking Costs Are More Processor Cores Good? Do You Need a Deca Core Processor? How to Check Number of Processor Cores Takeaway What is a Processor A processor A processor, also referred to as a Central Processing Unit CPU, is a computing engine inside a device. In layman’s terms, it is the brain of the computer. It provides the processing power for the tasks to achieve them. A processor is a miniature, logical circuit that performs the tasks delivered by different software. It is not necessary that a processor may have the same form factor as in the image above. For example, a mobile device’s processor may look something entirely different. Initially, a processor was only designed with a single “core.” Over time, additional technologies were developed to improve its performance, including the following Multiple Cores Processor manufacturers, such as Intel and AMD, started to include multiple cores into a single silicon chip a processor. This enabled each core to receive and perform individual tasks, simultaneously. Hyper-Threading Hyper-threading, a technological term by Intel, is a core’s ability to receive and process 2 individual tasks simultaneously, virtually splitting a single core into two. Clock Speed Each processor has a clock speed. This is the number at which a processor processes a stream of data. The greater the clock speed, the faster a processor will be, increasing the system’s performance. Clock speeds range from a few MegaHertz to several GigaHertz. Some advanced systems have multiple processors embedded in them, each of them having multiple cores as well. this is done to maximize productivity and performance. What is a Processor Core Multiple dual-core processors A processing core is a component that reads instructions and carries them out inside a processor. Most modern-day processors include multiple cores. The commonly-available processors today can have cores anywhere between 2 and 24. The more cores, the merrier. Each core can handle a different thread of data and process them at the same time. This results in faster loading times, less lag, and a greater overall user experience. A core functions on the following 4 principles, which is known as the “instruction cycle“ Fetch The processor core retrieves the awaiting instructions, typically from some type of memory. Decode Each component of the fetched data has a feature known as an “opcode” that instructs the processor core what to do with the data that follows it. The various parts of the processor core can then begin working once the core has worked everything out. Execute The processor now knows what needs to be done and actually performs the task at hand. Writeback At this stage, the core moves the processed data back to where it should go. All of this is done in one instruction cycle. Now imagine a ridiculously-fast core with extreme clock rates, and the processor has multiple cores to handle multiple threads at the same time. It would result in an absurd amount of data being processed in the blink of an eye. What is a Multi-Core Processor A quad-core processor “Multi” stands for more than one. A processor having more than one core will be considered a multi-core processor. When a processor has multiple cores integrated into the chipset, they are usually designed differently. For example, an octa-core processor may have 4 e-cores, which are the low-powered cores designed to handle less critical tasks, and the other 4 would be p-cores, which are performance cores, designed to handle power-intensive tasks.

Type of Work The first and most important consideration to make is what type of work you’ll be performing atop the processor. Will it be CPU-intensive, like graphic designing and image rendering, or will you only use it to edit your daily files or folders? If you plan on using it for day-to-day tasks, like editing an Excel sheet, then a dual or quad-core processor with a good clock speed may do the trick. However, if you are looking to play graphics-intensive games on the computer, then you may want to have an octa or deca-core processor. Power Consumption Another significant factor that should impact your decision is power consumption. Will be mostly on the go and not have frequent access to a power outlet, or do you plan on being always plugged in? If you want your laptop’s or phone’s battery to last longer, then you may want to choose a device with fewer cores, as the more cores there are, the faster your battery will drain. At this point, you may also want to glance at the core types. Are they all P-cores, or are their low-powered cores available on the chipset as well? Heat Dissipation The hat dissipation of a device is often overlooked. You need to make sure that your device will dissipate the heat as quickly as it generates it. More processing cores working in conjecture will mean more heat is produced. Therefore, you must be prepared to compensate for the extensive heat with cooling fans, liquid-cooled radiators, or other means. If you choose a dual or quad-core processor, then heat management would be easier and more cost-effective. Multitasking Do you plan on running 10 or more applications at the same time? If so, then you must go for the deca-core processors. The more cores there are, the more data threads your processor could handle simultaneously. This, in turn, will increase your system’s performance, and hence, your productivity. Of course, a decision cannot be made on multitasking alone. You must also consider the factors we have discussed above, like heat dissipation and power consumption. If you run maybe 5-6 apps at a time, then even a good quad-core processor might fulfill your needs. Costs Your budget is where it all comes to a halt. It will cost you more as you go higher up the ladder in terms of processor cores. Processors with a lower number of cores are relatively cheaper and abundantly available, whereas finding a processor with 10 or 12 cores might need some homework first. At this point, consider again what you will be doing with a processor if you choose one, and whether it is worth the price. Are More Processor Cores Good? It goes without saying; the more cores your processor has, the better performance it will give. Since it is then able to process more threads at the same time. However, we would like to add that you must also take into consideration the points that we have discussed above, like heat dissipation, costs, and power consumption. Do You Need a Deca Core Processor? Deca-core processors, or even octa-core ones, are sufficient for any vivid gamers, given that there isn’t another bottleneck on the system. You may also want a deca-core processor if you are a 3-D animator, or perform any sort of image and video rendering. However, if you have no dedicated goal of what you will do with your new PC or processor, then we recommend that you do not get a deca-core processor right now. Instead, go for a quad or a hexa-core, since those are sufficient to perform daily average tasks. How to Check Number of Processor Cores If you want to check how many physical and virtual cores your current processor has, here are the steps for Windows PC Open the Task Manager by pressing the CTRL + Shift + Esc hotkeys. Switch to the Performance tab and select “CPU.” View the “Cores” and the “Logical processors” in the details. View physical and virtual processor cores Takeaway The number of processor cores makes all the difference in your system’s performance. It is true that the more cores you have, the greater your computer or phone will perform, and the more responsive it will be. However, there are other things you must also consider before “going big.” In conclusion, you should get a device with a processor that meets your needs, with a little extra legroom to compensate for any unforeseen workloads that may befall you.

Um processador multinúcleo ou multi core, em inglês é aquele que tem dois dual ou mais núcleos quad, hexa, octa, deca-core… de processamento dentro de um chip. Isso quer dizer que os smartphones possuem dois ou mais núcleos responsáveis por dividir as tarefas. Em processadores de um só núcleo também é possível executar várias funções ao mesmo tempo. Porém, elas podem chegar ao limite da capacidade da CPU Unidade Central de Processamento com um desempenho que vai deixar a desejar. Como funciona um processador? Parece bem óbvio, mas os processadores processam um monte de dados solicitados pelos aplicativos que você usa. Para abrir navegadores, mensageiros e jogos, o processador precisa acessar o armazenamento interno e encontrar os dados referentes ao app, levá-los até a memória RAM e trabalhar nesta troca até exibir tudo na tela. É o processador que também vai receber as informações que você mesmo cria no teclado e enviá-las ao aplicativo, num vai e vem de dados. A memória RAM, como já falamos aqui antes, tem a missão de permitir que o processador tenha acesso imediato aos dados que deseja como um meio do caminho, contribuindo para uma maior rapidez e capacidade de resposta. Quando o processador precisa fazer alguma coisa de novo, consulta dados da memória RAM. O que significa core? Como você já pode imaginar, um processador dual-core trabalha com dois núcleos, um quad-core com quatro, um hexa com seis e assim por diante… Um bom processador oferece melhor desempenho ao smartphone para que consiga realizar suas tarefas sem comprometer a performance — evitando travamento, lentidão e outras intempéries. O sistema operacional do celular, no caso do Android, por exemplo, trata cada um desses núcleos como um processador diferente. Na maioria dos casos, cada unidade possui seu próprio cache. Contudo, os dois núcleos ou mais não se somam em capacidade de processamento, o que eles fazem é dividir as demandas, tornando-as mais fáceis e rápidas. Um processador dual-core com clock de GHz não equivale, por exemplo, a um processador single-core com clock de Ghz o dobro, e sim a dois núcleos GHz operando em paralelo. Quanto maior o clock calculado em GHz melhor será o seu desempenho para executar diversos programas simultaneamente sem engasgos. Como já deve ter notado, uma série de características influenciam no desempenho do processador. O que conhecemos como “velocidade” clock é o número seguido de GHz. O que é clock? Podemos definir o clock como o volume de ações escrever e ler dados ou executar comandos que o processador pode executar por segundo. Sendo os GHz um indicador imediato da “velocidade”. Quanto mais “pulsos de clock”, mais rápida a frequência. Isso tornou-se necessário para resfriar processadores single-core com frequências cada vez mais altas em GHz e que amontoavam uma concentração cada vez maior de transistores — com o passar do tempo cada vez menores — no mesmo circuito integrado. Fazendo uma analogia bem superficial, um núcleo é um motor. Então, é natural imaginar que um deca-core com dez núcleos é o melhor para um processador rápido e potente. Entretanto, um desempenho impecável depende do motor, depende do tipo de carga que precisa levar e depende também da sua rotina de uso e esforço do motor. Quanto mais núcleos, melhor o celular? Observar só o clock não basta. Há limites para quão rápido pode ser um processador que cabe dentro de um smartphone que cabe na sua mão sem que esquente demais. A solução encontrada pelas fabricantes foi fazer chips de processadores móveis com mais de um núcleo, que funcionam como se fosse um processador independente. Assim, o número total de ações que consegue realizar por “pulso de clock” é maior. 1 o fator software 👩🏾‍💻 Os fabricantes podem fazer com que processadores usem cada núcleo para determinadas tarefas e isso permite, por exemplo, ter uma melhor autonomia de energia usando os núcleos mais lentos para tarefas simples e os núcleos mais rápidos e poderoso para tarefas complexas. É o processador que vai organizar e definir quais processos serão executados em qual dos núcleos — é comum que haja uma combinação com velocidades diferentes. É possível, ainda, que o próprio aplicativo ofereça configurações para otimizar os processos. Sendo assim, ter um processador com muitos núcleos não implica ganho velocidade substancial, pois o sistema operacional ou aplicativos podem não usar recursos com maestria. 2 a memória de cache ⏳ Aliada à memória RAM, o processador tem ainda o que chamamos de memória de cache, um pequeno espaço de armazenamento de dados absurdamente rápido que fica no próprio chip para guardar dados que precisam ser acessados com muita frequência. A forma como essa pequena memória de cache é dividida entre os núcleos do processador varia bastante em cerca de três níveis L1, L2 e L3, sendo o L1 é o mais rápido e isso pode influenciar no resultado final do desempenho de um processador mesmo com muitos núcleos anunciados em propaganda, porém subutilizados. Como avaliar o processador de um smartphone? Certamente que você vai continuar observando a velocidade em GHz na ficha técnica dos celulares, mas deve levar em consideração que comparar processadores é muito mais do que avaliar “quem tem clock maior”. De acordo com a arquitetura adotada pela fabricante isto é, a maneira como o chip é construído, seu desempenho pode variar. E, lógico, como você não é um especialista nisso, não precisa se agarrar a quesitos tão técnicos ou se aprofundar na questão da memória de cache ou de como suas aplicações trabalham com os núcleos de um processador. É para isso que existem “benchmarks”. Como isso funciona? Análise técnicas simulam o desempenho de um ou mais chips em situações leves e severas. Ao final, cada um dos processadores recebe uma pontuação com base no seu desempenho. Se você estiver em dúvida entre dois smartphones com processadores de fabricantes diferentes, por exemplo, a melhor coisa é consultar pontuações em testes. O Tecnoblog costuma divulgar comparativos entre os melhores celulares e que usam processadores com arquiteturas completamente diferentes como a Apple e a Samsung. Um bom exemplo é o comparativo entre o A10 Fusion — o primeiro chip com CPU quad-core a equipar um iPhone — com o Snapdragon 845, um chip octa-core da Qualcomm. Conforme a pontuação do Geekbench, o processador do velho iPhone 7 e iPhone 7 Plus se sai melhor que o rival presente em Androids de Sony, Xiaomi, Samsung e LG, incluindo a linha Google Pixel 3. Para deixar um pouco mais complicado, você ainda tem processadores Exynos, da Samsung, em algumas versões de aparelhos. Outro exemplo de que total em núcleos não é documento é o A12 Bionic, da Apple, que é hexa-core. Comparado ao mesmo Snapdragon 845, da Qualcomm, o A12 tem reconhecidamente mais desempenho bruto, independente de otimizações de software. Um terceiro exemplo é o Exynos 9810, um octa-core de GHz, da Samsung em comparação com o Snapdragon 805, um quad-core de 2,65 GHz, da Qualcomm. Em tese, o modelo da Qualcomm tem maior velocidade em GHz, mas era um pesadelo para os usuários pois esquentava absurdamente, revelando desempenho insatisfatório e deixando o chip de oito núcleos da sul-coreana com menor frequência em vantagem. Vale notar que, em geral, as análises só levam em consideração o desempenho do processador sozinho e não o conjunto do smartphone por completo. Uma memória RAM lenta, uma memória flash lenta ou um software mal otimizado, podem botar tudo a perder mesmo em um celular equipado com processador de vários núcleos. Sendo assim, fica a dica veja comparativos técnicos, GHz não é tudo, há mais nisso aí.
