From what I've seen, most of the suggestions are for AMD CPUs. Any suggestions for Intel CPUs?
I'm planning to mine Monero, what hashrates should I expect from say a 7700k or a 9900k with the new CryptonightR algorithm?
Just suggest you get how much speculation for hash power that will you get from 7700k and 9900k series through the benchmark site of monero
https://monerobenchmarks.info/that benchmark is always getting updated.
It has already listed the new processor too. i hope that you help you a lot.
