Best gaming CPU: what is the top CPU for gaming in 2020?

We've tested all the top AMD and Intel processors to help you make the right choice

Best CPU for gaming

It’s difficult to choose the best gaming CPU in 2020 – there are simply too many great options. Unlike a few years ago, four cores and eight threads is now pretty standard even at the low-end. You can get affordable CPUs that dish out great single-core gaming performance not only in less intensive games like CS:GO, but also in many triple-A games like Call of Duty: Warzone and CPU-intensive applications that utilise all cores. All of this has meant there are more options than ever for those looking to create content, stream, play games, and use CPU-intensive applications for a pretty low cost.

Since AMD has decided to take the fight to Intel in terms of core count, even six-core CPUs are becoming more and more common thanks to this Intel vs. AMD battle. But despite the dominance of multi-core CPUs in today’s gaming rigs, the difficulty in optimising games and applications for chips with multiple cores has meant we’re still not seeing many modern game engines taking full advantage of the powerful CPUs many of us now have in our machines.

Having the best graphics card for gaming is still the best way to make games run as smooth as butter on your gaming rig. But that doesn’t mean any old processor will do – you still need a quality chip to get the most out of your graphics card.

Here are the best gaming CPUs:

AMD Ryzen 5 3600

The best gaming CPU is the AMD Ryzen 5 3600.

The AMD Ryzen 5 3600 isn’t just a great gaming CPU with serious multi-threading chops, it’s also incredibly good value. The previous Ryzen 5 2600 remains a solid choice for the value-oriented PC builder while stocks last and prices are low, but the Zen 2 architecture adds more than enough value to justify the latest and greatest chip. And while the Ryzen 5 3600X has a slightly higher clock speed than its non-X little brother, in games this translates to only a minute increase in frame rates for a decent chunk more money.

With a 15% IPC increase over second-gen Ryzen and Zen+, the Ryzen 5 3600 brings even more affordable gaming power to the mainstream market. At this price point, it doesn’t just creep up close to Intel’s gaming lead, it outruns it – and does so without demanding a bucket of power or pennies. And its multi-core/threaded performance makes it a great performer in areas other than gaming, too. There’s a caveat to all this though, which is the following. If you’re comfortable with overclocking, and if you’re in it mainly for the gaming performance, then the Core i5 10600K below might be a better bet.

Ryzen 9 3900X

The best high-end CPU is the AMD Ryzen 9 3900X.

The AMD Ryzen 9 3900X currently rules the Zen 2 roost and the multithreaded market. With 12 cores split into 24 threads, it’s got the raw power to chomp through almost any creative or professional workload. And thanks to Zen 2’s unique design, the 3900X’s dual chiplets manage to clock up to an impressive 4.6GHz. That’s enough to drive impressive frame rates in games, too.

There’s also little need to splash out on the latest motherboard. With an AM4 socket package fit for most Ryzen motherboards in the market, the Ryzen 9 3900X is not only in a league of its own, but a terrific value proposition, too. And while Intel’s Core i9 9900K, Core i9 10900K, and AMD’s Ryzen 9 3950X are faster, the Ryzen 9 3900X can’t be beaten for value at the top end of the market.

Intel Core i9 10900K

The fastest CPU for gaming is the Intel Core i9 10900K.

Intel’s new Core i9 10900K is the world’s fastest gaming CPU, but its painfully high price tag and TDP efficiency (or lack thereof) means it doesn’t take the spot as the outright best CPU for gaming. But if money really isn’t a thing for you, and if you have a monster CPU cooler then the deca-core from Intel is the best processor to pair with your high-end graphics card.

When it comes to GPU-bound games, which are the majority of titles, even with one of the best graphics cards there isn’t a huge amount of difference between the in-game performance of Intel’s top chip and AMD’s cheaper high-end CPUs, especially at 4K. It is a great chip from a technical and performance point of view, but as a value proposition – especially in the face of fierce competition from AMD – it’s a bit of a tough one to recommend.

What we like
Tick The fastest gaming processor around
Tick Perfect CPU for RTX 2080 Ti
Tick Fantastic single core gaming performance

Intel Core i5 10600K

The best CPU for overclocking is the Intel Core i5 10600K.

Intel’s Core i5 10600K is a much better value proposition against the Ryzen 5 3600 and Ryzen 7 3700X than its predecessor – the Core i5 9600K – was. The 10600K is a genuinely great chip for the price, as it trounces over the 3600, 3700X, and often even the 3900X in games.

The Ryzen 5 3600 still just about takes the title as the best gaming CPU because it offers better multi-core performance in CPU intensive apps, and because it’s still a cheaper option, but the 10600K is justifiable if you have your eyes set on gaming alone. And if it’s overclocking you’re after, the 10600K is the best chip for it. It’s super easy to get a few hundred MHz out of this processor, and this translates directly into frame rates, putting it close even to the 10900K. If you’re in it purely for gaming and overclocking, the 10600K can’t be beaten. If you have to choose between the 10600K and the 3600, ask yourself: am I comfortable slapping a good cooler on and overclocking? If so, the 10600K is probably the best choice for gaming. If not, stick with the 3600.

AMD Ryzen 7 3700X

The best CPU for productivity is the AMD Ryzen 7 3700X.

If you’re after a mix of high-end multi-threaded computational chops, decent gaming performance, and great value then look no further than the Ryzen 7 3700X. It’s a well-priced Zen 2 CPU that drastically improves on the overall performance of its predecessor, the 2700X, and yet requires way less power. Importantly it’s also considerably cheaper than either Intel’s or eight-core 9700K or i9 10900K.

But it’s still got gaming performance that’s comparable with Intel’s top chips when you’re gaming at 1440p or 4K. That makes it a great chip in productivity terms and a CPU with gaming performance that is practically indistinguishable from the Intel competition in any GPU-bound game.

What we like
Tick Serious multi-threaded performance
Tick Great value for a 16-thread CPU
Tick Top gaming performance

AMD ryzen 3 3300x

The best budget CPU is the AMD Ryzen 3 3300X.

Previously, the spot for the best cheap gaming CPU was reserved for AMD’s Ryzen 5 2600, the predecessor to the current best CPU for gaming: the AMD Ryzen 5 3600. But AMD has just released the ‘cheap as chips’ Ryzen 3 3300X, and it’s looking too tasty to leave off the charts on the budget end.

This 3rd-gen Ryzen processor is a four-core, eight-thread machine capable of boosting up to 4.3GHz, all at a low power cost of 65W TDP. Not only that, but it supports PCIe 4.0., giving it longevity above and beyond many of the current best CPUs for gaming. While its multi-core performance may still be slightly behind the Ryzen 5 2600, its single-core performance is much better – and that’s what matters for gaming. Keep your eye on this space, though, because Intel’s new Core i3 10300 might end up being a better budget gaming choice once the dust has settled on the new Comet Lake generation of CPUs.

What we like
Tick PCIe 4.0 support
Tick Great longevity
Tick Fantastic gaming performance for the price

CPU buying guide

Where for most of our PC gaming lives we’ve been recommending whichever Intel processor suited your budget it’s no longer that simple. And that’s down to the engineering efforts AMD has put into creating its latest Ryzen lineup of CPUs.

AMD has made it very difficult to recommend an Intel processor as the overall best CPU for gaming, given the fact that you get so much more for your money with an AMD chip right now. That and the gaming performance delta between them is now so small as to be completely inconsequential.

At the mainstream end it’s the six-core, 12-thread Ryzen 5 3600 for the win. It’s a great-value, processing monster – enough so that the 3600X is almost irrelevant. The Intel Core i5 10600K is the best bet if you’re only going to be gaming, though, and rarely expect to use intensive multi-core applications. If you’re a dab hand at overclocking, the 10600K looks even better and should be considered even more favourably against the 3600.

The Intel i5 8400 comes close, but thanks to Intel’s 14nm production woes, its pricing continues to fluctuate, making it not worth the money when the Ryzen 5 3600 is on the table. And, if you’re doing serious PC work alongside your gaming hobby, its six-core, six-thread design sits behind the AMD chips in pure multithreaded computational terms.

At the high-end, the ten-core, 20-thread Intel Core i9 10900K has lost out to the Ryzen 9 3900X. The Intel chip is simply more expensive and only really offers a tangible performance difference in CPU-bound games. Of which there are few. But over time, as GPU power increases, that will change and the 10900K might really start to shine.

And on the budget end, the new Ryzen 3 3300X will deliver a great level of hyperthreaded CPU performance, superb single core performance for gaming, and great longevity thanks to PCIe 4.0 support, all for a pretty low cost. A bona fide bargain.
