What CPU will bottleneck RX 7800 XT?

The RX 7800 TX is a high-end graphics card, so it will need a powerful CPU to avoid bottlenecks. The specific CPU that will bottleneck a RX 7800 TX will depend on the resolution and settings that you are using. However, some CPUs that are likely to bottleneck a RX 7800 TX include:

  • Intel Core i5-12400F
  • AMD Ryzen 5 5600X
  • Intel Core i7-11700K
  • AMD Ryzen 7 5800X

These CPUs will cause a bottleneck of more than 10% at 1080p resolution and ultra settings.
Intel Core i3 or low-end Core i5 CPUs (9th gen or older) – The 4 cores and low clock speeds of these older Intel CPUs will likely limit the performance of the powerful 7800 XT GPU in many games, especially at 1080p resolution.
AMD Ryzen 3 or Ryzen 5 CPUs (1st/2nd gen) – Early Ryzen chips like the Ryzen 5 1600 have relatively low per-core performance which could hamper the 7800 XT at lower resolutions when games need faster single threaded speeds.

How to Choose A Good CPU for Radeon RX 7800 XT

Here are some tips on choosing a good CPU to pair with the AMD Radeon RX 7800 XT GPU:

  • Look at 6 or 8 core CPUs – The 7800 XT can take advantage of the extra cores and threads in modern CPUs. Quad core CPUs will likely bottleneck it.
  • Prioritize per-core performance – High GHz boost clocks and strong single threaded speed are crucial, as many games rely heavily on 1-2 thread performance.
  • AMD Ryzen 5000 or newer recommended – Ryzen 5000 series and newer have excellent single thread and multi-core performance perfect for high-end GPUs.
  • Intel 12th/13th Gen Core i5 or i7 – Intel’s 12th and 13th gen Core processors compete well against Ryzen in gaming with high clock speeds.
  • Ensure the CPU has PCIe 4.0 support – This allows the 7800 XT to communicate at full bandwidth with a compatible motherboard.
  • Overclocking potential is a plus – Unlocked CPUs allow you to tune for even higher frequencies if desired.
  • Look at reviews and benchmarks – Check reviews and gaming FPS comparisons using the CPUs you’re considering with flagship GPUs.
  • Budget accordingly – Faster CPUs provide diminishing returns. Find the sweet spot between performance and price for your needs.

Following these tips will help identify the right CPU that avoids bottlenecking the 7800 XT at common resolutions, while making sense for your budget. The goal is balance between CPU and GPU.


For most gamers looking to get the most out of the powerful RX 7800 XT graphics card, the AMD Ryzen 7 7700X represents the best overall value. With its combination of high clock speeds, excellent single-threaded performance, and a healthy core count, the Ryzen 7 7700X avoids bottlenecking the 7800 XT while costing far less than top-end options.

The Intel Core i5-13600K is also a solid budget-friendly alternative for high FPS gaming with the 7800 XT, trading some multi-core performance for great single-threaded speed. 

Gamers focused entirely on pushing ultra high frame rates may want to consider the Intel Core i9-13900K or AMD Ryzen 9 7950X, but these provide diminishing returns considering their much higher costs.

Ultimately, the Ryzen 7 7700X hits the sweet spot of affordability and performance for smoothly powering the 7800 XT even in the most demanding games. Unless money is no object, the 7700X represents the best bang-for-buck CPU to pair with and get the most from an AMD Radeon RX 7800 XT GPU.
