If you want the absolute best Ryzen processor for the ASUS ROG X570 Crosshair VIII Extreme, look no further than the AMD Ryzen 9 5950X. It's the top-ranking desktop processor from AMD for the AM4 socket. This monster has 16 cores and 32 threads and is a perfect match for such a motherboard.
Sporting 12 cores and 24 threads, this is one impressive processor. It may be the entry-level Ryzen 9, but you've got more performance here than you'll likely need. You'll be able to overclock it using the ASUS UEFI BIOS to get even more out of the CPU for a killer enthusiast machine.
We wouldn't recommend using anything that isn't an AMD Ryzen 9 processor with this motherboard from ASUS, as it has many great features that this range of top-end CPUs would be able to truly utilize. Still, if you simply cannot afford one and don't want to go with a previous-gen chip, there's always the excellent mid-range Ryzen 7 5800X with eight cores and 16 threads.

The AMD Ryzen 9 5950X is the best CPU for consumers before entering Threadripper territory. It has an impressive 16 cores and 32 threads with a clock speed of 3.4GHz. You can even overclock this thing to extract yet more performance from the power-hungry CPU.
