Best CPU for NVIDIA GeForce RTX 3080 in 2023
Pair your ray-traced gaming with some processing power.
The best processor (CPU) for NVIDIA's GeForce RTX 3080 won't bottleneck the absolutely monstrous power coming from the card. In this case, AMD Ryzen 5000 Series CPUs are a great match, but Intel is also up there with its 12th Gen "Alder Lake" Core chips. We've rounded up the best CPUs if you have an RTX 3080 that needs a partner.
