Performance and Power of the Low-Cost EPYC 4005 vs. Original EPYC 7601 Zen 1

The first couple workloads didn't surprise me at all that the 4005 trounced, because it seemed obvious the avx512 was gonna help a lot.

But I thought the 2x core count and 8 channels 2666MHz (vs dual channel 5600MHz) would have some significant wins on application workloads like nginx! But man, the the EPYC 4585PX flagship smoked it in every way!

Power consumption was a lot closer than I expected. I thought for sure the 4005 was gonna be significantly lower power but overall not a huge difference.

Very fun & surprising to me comparison.
