03Best budget Intel CPU for AMD Radeon RX 7900 XTX & XT
The RX 7900 XTX & RX 7900 XT are AMD Radeon’s latest flagship graphics card releases. Alongside all the new hardware you might pick up for your new gaming rig – choosing the best CPU for RX 7900 XTX & XT might be the most important choice for you to make.
The RTX 4090 & RTX 4080 both demanded new CPUs due to their reliance on PCIe 5.0. Lovelace architecture in the RTX 40-series GPUs allows for double the data transfer between the GPU and processor due to PCIe 5.0’s higher bandwidth versus PCIe 4.0. The innovation doesn’t stop there either. Now that AMD Ryzen 9 7900X3D release date has been confirmed, a 3D cache CPU is not far away.

So, with the release of the RDNA 3 in late 2022, and sales displaying healthy demand, an obvious question is do you need a new CPU for the RX 7900 XTX or RX 7900 XT?
It’s likely that if you’re looking for the latest CPU for the RX 7900 XTX or RX 7900 XT, you’re going to be on the lookout for the best new CPUs like the Ryzen 9 7900, Ryzen 9 7900x or Intel 13th Gen CPU. That being said, unlike the RTX 40-series, the RDNA 3 graphics cards should be fully compatible with older CPUs. This process of selection has gotten even harder now that Ryzen has announced their new ‘Non-X’ versions of their 7000 range.
There is a chance that older processors with lower clock speeds and cache might throttle your new GPU slightly. Alongside that, something often overlooked in PC builds is the motherboard, of which we have suggested the best motherboard options here.
To cover all bases, we’re going to be offering a selection of processors that don’t compromise on quality and price throughout each processor generation, whilst also offering high-end performance options for your gaming pc at various price points.

Frequently Asked Questions
Are the RX 7900 XTX & RX 7900 XT compatible with all CPUs?
Most CPUs dating as far back to the early 2010s will likely be compatible with the RX 7900 XTX & XT, however we don’t recommend using CPUs dated before the Ryzen 3000 series or Intel 10th Gen as they may not be up to the task of working alongside such a powerful GPU.
Do the RX 7900 XTX or XT need an AMD CPU?
This is a common misconception, though if you’re building your own PC with the latest graphics card you don’t have to worry about pairing and Intel CPU with and AMD graphics card. They are designed for cross architecture support.
Can you use an AMD GPU with an Intel CPU?
Yes – Intel’s chips are designed to be compatible with all the most popular GPUs, this means they are compatible with all of AMD’s cards.
What features should I look out for in a CPU?
Make sure that your CPU matches your graphics card power and performance. You’ll need a high cache memory and the ability for your CPU to achieve high clock speeds. Though it’s tempting to go for the highest-performing CPU, you should check that your GPU won’t bottleneck first.
How much better is the RX 7900 XT than the 6950 XT?
The RX 7900 XT should perform about 1.4 – 1.6X better than the 6950 XT. It boasts 10752 FP32 cores and is helped by 5nm RDNA3 architecture. The 7900 XT GPU has a base clock of 1.5GHz and 2.4GHz boost. This is all while offering 20GB of GDDR6 memory, to help cut costs.
