The AVX-512 Performance Advantage With AMD EPYC Bergamo

Like with AMD EPYC Genoa(X), AVX-512 on Bergamo was proving beneficial in HPC and other workloads optimized for AVX-512.

While Sierra Forest will offer up to 144 E cores, Bergamo only goes up to 128 cores but with AVX-512 and other Zen 4C features it may prove more than capable of competing, assuming AVX10 isn't making it to Sierra Forest.

Cpuminer-opt did observe higher power consumption of the EPYC 9754 when using AVX-512, but the increase in power was easily justified by the performance boost.

As we are used to seeing, AVX-512 absolutely pays off for TensorFlow.

There was a big increase in CPU power consumption for TensorFlow when using AVX-512 to yield these big speed-ups.
