Patched Linux 5.11 Continues Looking Great For AMD Ryzen/EPYC Performance

Continuing to pound on various AMD Zen 2 / Zen 3 systems with this patched Linux 5.11 kernel continues to show the frequency invariance regression taken care of while also seeing many workloads with Linux 5.11 Schedutil performing better than Linux 5.10.

Linux 5.11 patched on this AMD EPYC 7F72 2P server is faster overall than Linux 5.10 with the more than one hundred benchmarks.

The monitoring of the CPU power consumption data for this 2P server does show Linux 5.11 with frequency invariance consuming around 10 Watts more on average than Linux 5.10 with Schedutil (+3.7%) as well as higher peaks in energy consumption. But at the same time during the moments of idling this AMD frequency invariance with Schedutil allowed for moments of much lower minimum power consumption (~60 Watts versus ~120 Watts on Linux 5.10).

More of the EPYC 7F72 2P benchmark data can be found via this OpenBenchmarking.org result file.

I am running more benchmarks still of the patched Linux 5.11 kernel but so far things are looking up for this patch that will hopefully be mainlined in the coming days to formally take care of this month old AMD Linux kernel regression.
