Best CPU for RX 7900XT

What is the best CPU for the new AMD GPUs?

Updated December 5, 2022 3:02 p.m

AMD has been on the rise in recent years, releasing CPUs that offer the best multi-core performance and GPUs that offer the best bang for the buck. And it seems we’ve reached that point again, with the 7000 series in the rearview mirror we’re fast approaching the launch of the 7900XT. But what is the best CPU for the RX 7900XT?

The 7900XT is the second best of the two GPUs launching this December, but that doesn’t mean it’s bad! The 7900XT brings a wealth of improvements to the table over the 6000 series GPUs.

RX 7900XT improvements

Before we dive into the best CPU for the RX 7900XT, let’s first think about why the GPU itself is so good and what improvements it offers.

The 7900XT should work approximately 1.4 to 1.6 times better than the 6950XT. With 10752FP32 cores and built on it 5 nm RDNA3 architecture. The 7900 XT is clocked at a Base clock of 1.5 GHz and 2.4 GHz boost. All this during the offer 20GB GDDR6 memory, to save costs. This Navi 31 XT GPU will boost AMD GPU performance. This is especially true for software help from the likes of FSR and SAM.

What is SAM? and how does it affect what CPU I get for the RX 7900XT?

SAM is an AMD technology called “Smart Access Memory”. It was first introduced with AMD’s 6000 series GPUs, allowing AMD CPUs and GPUs to work together more efficiently.

This efficiency has been increased by giving the AMD CPU access to the entire GPU VRAM at once, as opposed to a limited section. This allows the AMD CPU to access GPU memory from anywhere, meaning access speeds are faster. This equates to slightly faster GPU performance.

Although SAM will be introduced in 2020, it’s not a new technology, SAM is just AMD’s implementation of Resizable BAR.

Currently SAM only works with Ryzen 3000 CPUs and higher, with RDNA2 GPUs and higher.
