Actually, on Monero the highest-hashrate stuff is still high-end CPUs like the AMD Epyc, Threadripper, and some of the top-end Intel many-core server CPUs.
The only GPU that can get into the 1000 hash/sec range is the Vega, per ONE report from ONE person - everything else that manages over 1000 hash/sec is a CPU - and the highest single-CPU report I've seen to date was an Epyc pulling over 3000 hash/sec vs the Vega at 1800.
Actually Vega is widely known to do 1800h/s minimum with registry mods. I didn't mod them and my vega64s do 1500h/s at 160W. CPUs with a ton of L3 cache does very well with monero, but GPUs are better price to perf wise.
CPU only coins are also vulnerable to botnet mining.
