The Best CPUs for Gaming in 2021

best cpu for gaming

When building a perfect gaming rig, the focus usually goes to the graphics card, since the positive gaming experience depends largely on its performance and quality. CPU is secondary hardware in this puzzle, but should it really be like that?

Most people don’t use their gaming PCs strictly for gaming, but also for many other tasks, which is where the significance of CPU comes into the picture. This is the main reason why choosing the best CPU for gaming shouldn’t involve just a gaming component, but be observed from a broader perspective.

Maybe your gaming demands only for a Pentium processor, but what if you are also into casual rendering, or content creation, not to mention 4k video streaming or similar? Your CPU will simply be unable to complete all that.

Also, you must take into consideration the fact that the games’ system requirements are constantly rising. Therefore, when purchasing a new CPU, you should always be at least one step ahead and always get yourself something that will allow for decent gaming at least for a couple of years to come, without a need for hardware improvements.

How to Choose the Best CPU for Gaming

If you are not familiar with the important aspects of a CPU, or just need a quick refresher, here are the most important characteristics of processors you should pay your attention to.

Clock Speed/Operating Frequency

Clock speed is probably the most important CPU characteristic. The higher it is, the quicker your tasks will be finished. Therefore, always go for higher numbers, which includes both high base and boost clock speeds.


Cores are necessary for multitasking, but more cores don’t guarantee for fast performance. If you have a dual core with a speed of 3.6 GHz and a quad-core processor with a speed of 2 GHz, the dual core will be faster, and it will completely outperform the quad-core.

Don’t be fooled and drawn by the high number of cores, six or eight cores are the maximum you will need, while the majority of the users are perfectly good with just four. Only the heavy users will demand 16 or so cores. For that reason, first of all, look at the processor’s speed and only after that check number of cores that should, as mentioned, be at least four.


If you are building a brand new rig, you should purchase a CPU with the same socket as your motherboard. Keep that in mind whenever you are building your own PC: all the components need to be compatible and the same socket of your motherboard and the CPU is a necessity.

CPU Cache

More CPU cache means that the CPU will have more space to store the copies of the most frequently used data. In other words, the more CPU cache MBs, the quicker the data access and overall faster computing. Because of that, just as in the case of a clock speed, always go for higher values.

9 Best Gaming CPUs

Intel Core i9 10900K

A Perfect Gaming Tool

intel core i9 10900k
Intel Core i9 10900K presents the sheer top of the Comet Lake lineup and, due to its superb gaming and single-core performance, is undoubtedly among the best CPUs available.

This processor comes with 3.7GHz base speed and 5.3GHz maximum turbo speed, as well as 10 cores and 20 threads. In other words, when paired with some of the best gaming motherboards out there, the premium performance is guaranteed.

Its single-core performance is a bit better than the AMD’s flagship, Ryzen 9 5950X that offers better framerates only when paired with the PCIe 4.0 compatible GPUs (Intel Core i9 10900K supports only PCIe 3.0), such as GeForce RTX 3090, that turn the results into Ryzen’s favor. However, have in mind that this processor costs significantly more; therefore, if you are after top-shelf gaming performance, Intel Core i9 10900K is a better option.

On the other hand, what isn’t that great is its multi-thread performance, which isn’t bad, but it is worse than that of Ryzen 3000 and especially the new Ryzen 5000 processors, which leaves it far behind in the productivity area.

When talking about other aspects of this CPU, you should know that it comes with improved temperature values when compared to its predecessor and that its TDP is 125W; however, that is only the base power consumption and in reality, these values can rise even above the 300W mark, which is certainly a lot, even for a high-end processor.

Also, this CPU is fitted with a well-established Intel UHD Graphics 630; it supports two-channel DDR4 2933 MHz memories and comes with 20 MB of L3 cache. Moreover, it has 40 PCIe lanes, as well as a whole bunch of features such as Thermal Velocity Boost, Intel InTru 3D Technology, Intel Clear Video Technology, and many more that certainly add to its overall value.

Simply, Intel Core i9 10900K has a lot to offer, especially to enthusiasts and high-demanding gamers. However, the dominant times, in which many of the previous generation Intel CPUs have indulged and had supremacy over the AMD rivals, are behind us. Nevertheless, for now, the number one spot among the gaming processors, is still in Intel’s hands and their Intel Core i9 10900K.

  • It is excellent in single and multi-thread operations
  • Great gaming performance
  • Unlocked multiplier
  • Improved temperatures
