AMD 4th Gen EPYC 9654 "Genoa" AVX-512 Performance Analysis

Phoronix - Mon, 12/19/2022 - 23:00
With the great AMD 4th Gen EPYC Linux performance showing significant generational uplift and dominating against the current Xeon Scalable "Ice Lake" competition, it's a combination of the twelve channels of DDR5 system memory support, up to 96 cores per socket, introduction of AVX-512, and other Zen 4 micro-architectural improvements. As follow-up testing articles to all of the Genoa data delivered thus far, over the weeks ahead I have additional benchmark results to share looking more closely at these different areas of improvement for AMD 4th Gen EPYC. In today's article is a look at the EPYC 9654 2P performance with AVX-512 on/off while also looking at the CPU power consumption impact and the affect on CPU clock frequencies and thermals.
