Claymore's CPU miner have a highest hs
So far, Claymore hashrate on v8 is zero. I benched it for v7 on Ryzen and always found it was the worst CPU miner among xmrig, stak and cpuminer-opt. Overall, i started to make my own miners when Claymore gave up making good CN ones. Claymore GPU 9.7 was a piece of art, then things when worse and worse.About the temperature, i don't say it's wrong, i didn't went as far as benching the temperature on CPU
I aim at absolute performance on a well configured rig, not coolest temp.
I got some mixed results on Intel, but on big AMD the consensus is that i'm the fastest on v7 (v8 is too recent). Maybe take time to configure it well.
One bonus point for Claymore: he also gave up his fees, which is very fair.
