The Best GPU for Budget PCs: CPU/GPU Scaling Tested
If you're looking to upgrade the graphics card in a budget or older PC, buying a faster GPU doesn't necessarily mean you'll get better gaming performance. In fact, our testing shows that a Radeon RX 9060 XT can actually outperform the more powerful GeForce RTX 5070 when paired with a slower processor. It sounds counterintuitive, but there's a good reason for it.
Recently, we revisited Nvidia's CPU driver overhead issue and found that it can still be a problem for GeForce RTX 50 series GPUs. In that test, we compared the RTX 5070 Ti and Radeon RX 9070 XT using the Ryzen 5 5600, which admittedly is quite a slow CPU to pair with such expensive modern graphics cards.
However, as we've found in previous testing, this is an architectural issue that can affect GeForce GPUs beyondthe RTX 5070 Ti. Logically, then, we should see similar behavior with...
