The Radeon RX 7800 XT is one of the best cards in the RX 7000 series, bringing the full power of AMD’s latest RDNA 3 architecture, and from the get-go, it packs a punch in 1440p gaming. If you are considering building a new gaming PC and are on the hunt for the best CPU for the RX 7800 XT, you have a few choices ahead of you. No matter if you are here for the best performance or seek a budget-friendly CPU, there is a processor here for you.

If you’re stuck on time and don’t want to read the full article, we have chosen the AMD Ryzen 7 7800X3D as our best CPU for the 7800 XT. This 8-core 16-tread offers more than enough processing power to support the RX 7800 XT in any endeavor, whether that be gaming, simulation, or data science workloads.

Plus, it’s always nice to have an all-one brand ecosystem, if you can help it. AMD rewards you for this with later generations by granting you access to SAM, which can offer a small performance increase in certain situations. Who doesn’t love free FPS?

Do you need a high-end CPU for the RX 7800 XT?

As a mid-range GPU, it will run comfortably with a range of processors from AMD and Intel. In an ideal scenario, the namesake 7800X3D would be a great choice and offer some headroom for an upgrade too.

If you’re planning on upgrading to a full 4K setup eventually, then a 13900K or 7900X will work, however, we feel the Ryzen 7 / Intel Core I7 is the best course of action for this GPU. You may also want to grab the best thermal paste to ensure you get the absolute best performance from your new CPU.

We’ve only calculated a bottleneck of around 18% in 1440p, which sounds like a lot but it isn’t, besides, this GPU was made for 4k gaming (with a little help from FSR)

  • 3D V-Cache design
  • Extraordinary gaming performance
  • Solid productivity performance
  • Reasonable power draw
  • Locked multiplier

As always, AMD’s new 3D V-Cache Cpus have been top picks for beefy GPUs, and the 7800 XT is no exception to this rule. This CPU provides incredible single-core performance in every game out there. 

Based on the new Zen 4 architecture, the 7800X3D boasts a whopping 8 cores and 16 threads that boost their way up to 5.0 GHz. And the incredible amount of L3 Cache just takes the cake. It doesn’t take much to cool this CPU. Due to its newer Zen 4 architecture, the 7800X3D tops off at 120 watts, which puts it in a decent spot in the market. 

But there’s one downside if we talk about it. This CPU can’t be overclocked as was the case with previous X3D processors. However, you can use PBO and Curve Optimizer to tweak things a bit. All-in-all, this CPU shines when it comes to a value proposition, giving you the best performance compared to its Intel counterpart.

  • Superb single-threaded performance
  • High overclocking headroom
  • Excellent productivity performance
  • Relatively high power draw

Intel substantially changed things up with its newer Alder Lake lineup, particularly when it comes to IPC and performance-per-watt metrics. And keeping this all in mind, it’s a strong pair with the 7800 XT. 

But let’s talk about the CPU for now. With the i7 13700K, you get a respectable 16 cores which feature 8 E-cores and 8 P-cores. But when it comes to threads, you get a whopping 24 threads in total. It excels in both gaming and productivity tasks and has a solid boost clock, topping off at 5.4 GHz. But due to its aggressive nature and turbo specs, the Intel Core i7 13700K does tend to get a bit toasty. 

It utilizes all of its 125W TDP on a full load. In comparison with the locked multiplier of the 7800X3D, the 13700K comes in with an unlocked multiplier, allowing users to fiddle around with their clock speeds to attain unmatched performance.

  • Great overall gaming performance for the price
  • Overclockable
  • Solid value
  • Less powerful than the above

The AMD Ryzen 5 7600X is a strong value option when it comes to marrying it with the 7800XT. It gives you the absolute bang for your buck without compromising much on performance. With this CPU, you get a decent number of 6 cores and 13 threads.

The CPU boosts to 5.3 GHz and comes with some incredible single-core performance in its price bracket. And there are a few key benefits when it comes to performance per watt and IPC as a whole. This CPU comes in with a TDP of 105W and manages to stay relatively cool under tight loads.

And the best part is that you get an unlocked multiplier to tinker around with your clock speeds and find your sweet spot for gaming.

While Intel had been struggling when it came to its midrange lineup for the past couple of years, they managed to pull off a 180 with their new mid-range budget-friendly king. Cue in the Intel Core i5 13600K represents a sweet spot when it comes to both performance and budget. Despite its lower price point, you get exceptional single-core performance with the 13600K. 

It packs a punch with a combined 14 cores and 20 threads. This makes it perfect for both gaming and daily productivity tasks if you’re not all that heavy on gaming. And as for cooling, things are pretty much mainstream with its 125W TDP. 

And like most K processors, the Core i5 13600K is an unlocked processor that allows you to tinker around with your clock speeds. With a decent CPU cooler, you can manage to pull off a stable 5.6GHz on its P-cores.


Will the 7800 XT play games in 4k?

Yes, the 7800 XT will play most games in 4k at a reasonable frame rate. More intensive AAA titles may have to be turned down a touch in the settings department, or you might have to deploy FSR to help you.

Does socket matter when choosing a CPU for a GPU?

Yes, the socket does matter, although you’d never really choose a specific socket for a GPU, you’d choose a CPU for the GPU, that then has a certain socket.

AM5 is pretty new, so you know your least AMD graphics card will likely be supported, however, if you’re looking to pair this GPU with an older generation Intel CPU, you might miss out on an updated PCIe generation.

Chipsets are more relevant to the question than sockets are, chipsets are sort of subdivisions of a motherboard set belonging to a socket. Take AM5 for example, the X670 chipset is the higher number and offers more connectivity, better power delivery, and the latest PCIe storage and GPU technology.

In Summary

That pretty much wraps up our best CPU picks for the 7800 XT. This GPU, along with the RX 7700 XT challenges the new and old-gen mid-range champions, also giving its Nvidia counterpart a run for its money, the Nvidia RTX 4070 a run for its money.

We have chosen the 7800X3D as the best CPU for the 7800XT. Its exceptional performance in gaming, thanks to that fantastic 3D-stacked cache, is almost unrivaled by Intel at this price point, and it offers plenty of processing power to back up the 7800 XT in almost any workload you can throw at it. The Ryzen 7 7800X3D will certainly make a great pairing with the 7800 XT for 1440p and 4k gaming scenarios.
