For years, if you wanted the best gaming CPU then there was only one choice: Intel. But since AMD came out swinging with its stellar Ryzen line of CPUs, all that’s changed. There’s now a wealth of different options to find the best gaming CPU for you.
While this is awesome, it also means picking the right processor for your gaming PC is a complicated task. It isn’t a decision you want to get wrong, since it’s a long-term choice.
The processor decides how powerful your PC is overall and can make a big difference in frame rates when gaming, even if you have the best graphics card. In this group test, we’ve picked out a selection of options of various prices and from both AMD and Intel, so no matter your budget or requirements, we should have the right CPU for you.
We’ve done a quick summary of our list if you can’t be bothered scrolling down:
- Most powerful gaming CPU: Intel Core i9-9900K
- Best budget gaming CPU: AMD Ryzen 7 2700X
- Best value gaming CPU: Intel Core i7-8700K
- Most versatile gaming processor: AMD Ryzen 3900X
Of course, a processor is not the most important component for high-end gaming, as a graphics card will make a much greater impact. If you’re on a budget and want the best possible gaming performance you’re better off buying a budget CPU and spending the cash you save on a premium GPU.

1. Intel Core i9-9900K
Most powerful gaming CPU
- Ultimate performance for gaming
- Ultra speedy for video rendering
- Best clock speeds of all the consumer CPUs
- Price cut sees improved value
- Not a huge gaming upgrade from previous generation
- Requires powerful cooler to prevent overheating
- Not much room for overclocking
The Intel Core i9-9900K is the ultimate gaming processor currently available, flaunting the best performance out of any chips we’ve tested yet thanks to its 5GHz boosted clock speeds.
This is really only recommended for serious gamers though, with the Intel Core i7-8700K a better value proposition with only a slightly worse gaming performance, while the AMD Ryzen 3900X chip is a better option if you’re regularly dipping into multimedia editing tasks thanks to its superior core and thread count.
It’s also worth noting the Intel Core i9-9900K can run hot after prolonged gaming sessions, so you’ll want a powerful cooler to pair with it for optimum performance.
2. AMD Ryzen 7 2700X
Best budget gaming processor
- Ultra-affordable price
- Excellent all round performance
- Improved overclocking
- Slower clock speeds than Intel rivals
- Slower than Intel for gaming
- Higher TDP than 1800X
The AMD Ryzen 7 2700X is our top recommended gaming CPU for those on a budget. It may be the weakest chip in terms of gaming performance on this list, but it’s frame rate results are shockingly not too far away from Intel’s very best offerings.
With just as many cores as the Intel Core i9-9900K, this is also a very good CPU for multitasking, media work and playing complex strategy games such as Civilization and Total War titles.
At £299 (at the time of writing) this is seriously cheaper than the Intel Core i9-9900K, and while you will be losing out on a few frame rates here, it will still easily run AAA at a top-notch performance as long as it’s paired with a quality graphics card.
3. Intel Core i7-8700K
Best value gaming CPU
- Fantastic gaming performance
- Incredible value
- Highly overclockable
- Low multi-core performance
- Only six cores and 12 threads
The Intel Core i7-8700K hits the sweet spot for gaming, offering a very similar performance to the Intel Core i9-9900K but at a more affordable price.
If you’re playing the likes of shooters and adventure games, the Intel Core i7-8700K will offer one of the best frame rate performance in the business. The one area where this chip falls down on though, is multi-core performance, which could be a problem for large scale strategy games where AI processing times is crucial.
The biggest issue with the Intel Core i7-8700K however, is its lacklustre performance for creative tasks. It’s not the greatest chip for multitasking since it only has six cores and 12 threads. But if you’re using your computer exclusively for basic productivity tasks and shooter games, then this processor will serve you diligently.
4. AMD Ryzen 3900X
Most versatile gaming processor
- Top-class multi-core performance for strategy games
- PCIe Gen 4 support for faster SSD speeds
- Amazing versatility for creative tasks
- Intel i9-9900K has the edge for gaming at cheaper price
- Included cooler not powerful enough
It feels like a disservice to put the AMD Ryzen 3900X so low down our Best Gaming CPU ranking since it’s such a quality processor. That said, you’ll generally see a superior raw gaming performance from the Intel Core i9-9900K despite it being markedly cheaper.
Where the AMD Ryzen 3900X does excel however, is multi-core performance. If you’re playing a strategy game which is loading multiple sprites on the screen at once, or calculating complex AI decisions, then the AMD Ryzen 3900X looks to be one of the best suited CPUs available.
But it’s biggest strength is versatility. If you’re looking for a processor capable of blitzing through 4K video editing, animation and the like, while also running some of the most demanding AAA games around on your downtime, then the AMD Ryzen 3900X is the perfect choice. Just note the stock cooler isn’t powerful enough to squeeze out every drop of performance, so you’ll need to splash further money on a cooler to reap all of its benefits.
