It's interesting but it was 5 GHz, not very practical. My i9-9940x slows from 4.3 GHz (all cores) to 3.5 when running AVX512.
I've been trying to vectorize verthash and AVX512 is slower than AVX2. I presume the significantly lower clock rate
slows down data file access, negating any gains from code optimization.
I also presume eth would have the same issues with the DAG.
I'm also not aware of any usable CPU miners for Eth.
the 11900K runs hot with AVX512 under constant load.. i was getting 100C steady with a 360mm AIO system (corsair h150i).
I had to stop running avx512 for the time being.
I've got a cooler master sub-zero system (thermoelectric cooling system) from newegg showing up in a few days... will put that in the system and try avx512 again.
