Does anyone know if the frequency throttling caused by AVX512 can be circumvented with high-performance CPU cooling?
It would at a first glance appear the throttling is not caused by temperature spikes but rather just executing the instructions at all.
I wonder how much more FP performance one could extract out of an AVX512 CPU with extreme cooling.
- pstrateman 6y agoOn Intel CPUs AVX512 instructions always block boost clocks, regardless of actual power budget or cooling capacity. Indeed the boost clocks are on a hard timer in general and cannot run continuously.
- anticensor 6y agoNot unless you want erroneous results.
- TinkersW 6y agoThe throttling will surely be reduced when Intel gets its process issues resolved(7nm), which is probably around when they finally ship AVX512 on desktop.
