Best gaming CPU 2024

We'll help you find the best gaming CPU for your system, with AMD Ryzen and Intel Core processors both offering unique performance advantages.

Best gaming CPU - Intel and AMD CPUs on a gradient background

The best gaming CPU plays a large part in determining the capabilities of your system. This bit of silicon can make all the difference in hitting your target average frame rates, particularly if you play on a high refresh rate display or enjoy gaming with ray tracing enabled. 

The two main players are AMD and Intel, and competition has never been more fierce, with the 14th Gen Core and Ryzen 7000 series each offering high performance levels. You’re spoiled for choice when it comes to picking the perfect processor for your PC, which is why we’re here to make your search easier.

The AMD Ryzen 7 7800X3D rules the roost according to our testing. However, the Intel Core i9 14900K can pull ahead in some benchmarks, providing you have a strong enough cooler and power supply to tame that particular beast.

When looking for a new CPU, we suggest options with at least six cores. Hexacore chips are now the standard among gamers, and a growing number of AAA PC games expect as much. There are great current generation options that fit this bill, like the AMD Ryzen 5 7600X, but don’t feel sheepish about opting for a 12th Gen Core or Ryzen 5000 series model, as they’ll be fine for years to come too.

Why you can trust our advice ✔ At PCGamesN, our experts spend hours testing hardware and reviewing games and VPNs. We share honest, unbiased opinions to help you buy the best. Find out how we test.

Intel Core i5 12400F

Best budget gaming CPU

Today’s best deals
Intel Core i5 12400F specifications:
Socket LGA 1700
Cores (P+E) 6 (6+0)
Threads 12
Base clock 2.5GHz
Boost clock 4.4GHz
L3 cache 18MB
TDP 65W
Reasons to buy
  • Six P-Cores
  • Amazing price
  • Solid gaming performance
Reasons to avoid
  • Clock speed could be higher
  • No E-Cores
  • No integrated GPU

If you’re looking to build a gaming PC on a very tight budget, the Intel Core i5 12400F is a bargain CPU. The price is amazing for the gaming performance on offer. Unlike newer budget CPUs, such as the Core i3 13100, the Core i5 12400F has six P-Cores under its heat spreader, rather than just four, giving it plenty of raw horsepower in games.

Don’t be fooled by the ‘12’ in this CPU’s model number either – the Alder Lake architecture used by this chip is very similar to the Raptor Lake architecture used in Intel’s latest 14th gen CPUs, and we’ve found it more than capable when it comes to gaming. Unlike AMD’s AM5 CPUs, you can run the Core i5 12400F with your old DDR4 memory if you have some in an existing system, and it will happily run an old motherboard with a B660 chipset.

With its TDP of just 65W, this CPU also doesn’t need a massive AIO cooler to keep it in check – a decent air cooler will do the job fine. There are a few catches. One is that this ‘F’ model has no integrated GPU, but that’s not an issue if you buy a separate graphics card for gaming. It also doesn’t have any of Intel’s E-Cores, which provide a boost in multi-threaded work, but these are largely irrelevant when it comes to performance in most games.

The peak clock speed of just 4.4GHz could also be higher, and this isn’t a K-series CPU either, so you can’t officially overclock it with the multiplier but you can’t have everything at this price. This is the best option if you want a decent gaming CPU for the cheapest price possible.

Intel Core i5 13400F

Best value gaming CPU

Today’s best deals
Intel Core i5 13400F specifications:
Socket LGA 1700
Cores (P+E) 10 (6+4)
Threads 16
Base clock 2.50GHz / 1.80GHz
Boost clock Up to 4.60GHz / 3.30GHz
L3 cache 18MB
TDP 65W
Reasons to buy
  • Generous price
  • Slightly higher clock speed than 12400F
  • Four E-Cores over 12400F
Reasons to avoid
  • No overclocking capabilities
  • Limited boost clock
  • No integrated GPU

If you want to get a decent gaming CPU on a tight budget, but also want a bit of a boost in multi-threaded work such as video encoding and rendering, the Core i5 13400F is a solid candidate. It features six of Intel’s latest Raptor Lake P-Cores and a 4.6GHz boost clock, making it a capable processor for gaming, but it also has an added bonus over the 12400F.

Unlike its predecessor, the 13400F also has four of Intel’s low-power E-Cores under its heat spreader, giving you a total of ten cores, which gives it a boost in multi-threaded software. It’s an ideal choice for anyone who does more than just game with their system but doesn’t have a huge amount of money to spend.

Like the 12400F, this chip doesn’t have a K in its model name, which means it can’t officially be overclocked by changing the multiplier, and the F means it doesn’t have an integrated GPU either. However, the latter enables you to save some money if you’re buying a dedicated graphics card anyway.

You won’t need an enormously powerful AIO cooler to keep this CPU in check either, and if you buy the retail version you’ll even get an adequate Intel stock air cooler included in the box.

Boost clock Up to 5.30GHz
L3 cache 32MB
TDP 105W
Reasons to buy
  • Lion’s share of Zen 4 performance
  • Outperforms last-generation flagship processors
Reasons to avoid
  • No included cooler
  • Runs hotter than non-X version

When we tested the AMD Ryzen 5 7600X, we found that the Zen 4 processor packs a potent performance punch that’s strong enough to run with the most powerful GPUs of today. This makes it a prime candidate for just about any build you could think of, regardless of size or power.

Despite sitting at the lower end of the Ryzen 7000 series stack, the 7600X handily outperforms previous generation flagships when it comes to gaming. Better still, you’re not missing out on many frames at all by opting for it versus its more expensive siblings.

It’s worth bearing in mind, however, that you’ll want to pair the 7600X with suitably strong cooling as it doesn’t come with a stock cooler. Don’t forget that you’ll need a new motherboard too, as well as some sticks of DDR5 RAM.

AMD Ryzen 5 8600G

Best gaming CPU with integrated graphics

Today’s best deals
AMD Ryzen 5 8600G specifications:
Socket AM5
Cores (P+E) 6
Threads 12
Base clock 4.3GHz
Boost clock 5GHz
L3 cache 16MB
TDP 65W
Reasons to buy
  • Best value iGPU on the market
  • Included air cooler
  • Good CPU performance in games
Reasons to avoid
  • 6,000MHz+ RAM is a must for iGPU
  • So-so value versus cheap graphics card
  • Doesn’t have 16x PCIe 4.0 lanes

For those needing a single chip that can handle CPU and GPU duties, perhaps for building a small system, or if you’re just on a tight budget, look no further than the Ryzen 5 8600G. With six Zen 4 cores and a Radeon 760M integrated GPU, it’s a perky performer as a processor and stand-in graphics card.

The 8600G shines brightest in less demanding games, but it’s still capable of playing the likes of Cyberpunk 2077 at 30fps if you’re comfortable with playing at 1080p using low settings. It’s compatible with FidelityFX Super Resolution too, which can help boost frame rates further through upscaling and frame generation.

You’ll need to pair the 8600G with DDR5 RAM clocked at 6,000MHz or above to get the most performance out of its integrated graphics. While this does add to the total cost of putting together a system, you can use the same RAM if you upgrade your CPU in the future.

If you plan to pair the 8600G with a dedicated graphics card, it only supports a limited number of PCIe 4.0 lanes. This is less of a problem with current generation pixel pushers (Radeon RX 7000 and GeForce RTX 40 series), but it will limit the bandwidth of future graphics cards that use the PCIe 5.0 interface.

Socket AM5
Cores (P+E) 16
Threads 32
Base clock 4.50GHz
Boost clock Up to 5.70GHz
L3 cache 64MB
TDP 170W
Reasons to buy
  • Great power efficiency
  • So much multi-core power
  • Eco mode works great
Reasons to avoid
  • Gets hot in multi-threaded workloads
  • Specs benefit production workloads more than gaming
  • High price

You’ll find the AMD Ryzen 9 7950X at the top of Team Red’s latest processor series. In this chip lies the very best that Zen 4 has to offer, with the flagship hiding some surprising tricks up its sleeve.

While this chip doesn’t boast a higher core or thread count compared to previous generation offerings, they are clocked much higher. This not only translates into higher frames per second but also greatly improves performance in just about every application that can make use of multiple CPU cores.

Its greatest trick, however, is its ‘Eco Mode’, which can force the processor to draw a maximum of 65W. Even with such low power consumption, it can still trade blows with top-tier processors. Naturally, you’ll get the most out of the chip while running at its standard 170W TDP, but it makes the prospect of a small form factor build featuring the 7950X more possibility than a dream.

Best CPU for gaming FAQ

How we tested the best gaming CPUs

There are a lot of gaming CPUs on the market, and it can be hard to know which processors are genuinely worth your money. To help you decide which CPU is right for your system and budget, we evaluate each chip’s gaming capabilities paired with the most powerful graphics cards, including the AMD Radeon RX 7900 XTX and Nvidia GeForce RTX 4090.

When we test gaming CPUs, our benchmarks include our usual suite of PC games with a few extra additions, including 3DMark, Civilization VI, and Cinebench 2024. We also observe what temperatures the processor hits under load, noting how long it can maintain its advertised boost clock speeds.

How do I choose a CPU for gaming?

Once you’ve figured out your budget, choosing the right CPU for your system comes down to what you plan to use it for. Do you play games at 60fps, 120fps, or higher? Do you play competitive shooters and RTS games or lean more toward action-adventure games or RPGs? All of these variables should impact your purchase decision.

Core i5 and Ryzen 5 chips pack plenty of processing power to sate most people’s needs. If you’re looking for more CPU performance you should opt for Core i7 and Ryzen 7 options. While Ryzen 9 and Core i9 options offer more power still, they’re best suited for production workloads. Ryzen 3 and Core i3 are still solid options for budget builders, but opting for a more expensive chip is ideal.

Can I upgrade my CPU?

To upgrade the CPU in your gaming PC, you’ll need to physically swap it out for one of the more powerful processors in this list. It’s more straightforward than you’d think, provided you have a compatible chip, an adequate cooling solution, and the right tools.

Check that a new CPU is compatible with your motherboard before upgrading. Intel’s compatibility tool lets you look up any Intel processor and view all compatible motherboards, while AMD’s search tool does a similar thing.

When you’re ready, our 7-step CPU upgrade guide has plenty of advice on installing a new processor.

When to upgrade CPU for gaming

There isn’t a set amount of time that a CPU will last you, but there are several ways to determine the best time to replace your CPU. Either you’ll find that your current system has slowed and is no longer meeting your needs, you have a fast processing speed and want to keep it that way, or you want to futureproof yourself with the latest processor.

If you’re unsure whether the CPU is the weak link in your gaming machine, there are tools to help you figure it out. CapFrameX and Rivatuner Statistics Server can display CPU and GPU loads when you boot a game with it running in the background. If your GPU hovers around 90-100%, upgrading to the best graphics card you can will be better than a CPU upgrade.

What should CPU usage be when gaming?

In a balanced system (i.e. a PC with a CPU and GPU of similar caliber, think RX 7700 XT and Ryzen 5 7600 or RTX 4090 and Core i9 14900K) your CPU usage will largely depend on the types of games you’re playing.

Certain genres, such as RTS games, will lean more heavily on the CPU as more computational performance is required to manage things like artificial intelligence. That said, more often than not, your GPU usage will be at 100% long before your processor is but higher frame rates (120+) will put more strain on it.
