AMD EPYC 7003 Series Performance Across Autumn 2021 Linux Distributions
From OpenBenchmarking.org you can see 65 different tests in total for these distributions on this AMD EPYC 75F3 2P server.
Coming in first place 66% of the time was Intel's Clear Linux followed by Ubuntu 21.10 and CentOS Stream being tied in second place for wins 10% of the time.
Coming most often in last place was Ubuntu 21.10 where it was in last 30% of the time, even with all of the performance strides made from Ubuntu 21.04 to 21.10. AlmaLinux 8.4 with its aging RHEL8 base was in last place second most often behind Ubuntu.
When taking the geometric mean of all the benchmarks that successfully ran on all five Linux distributions, Clear Linux had a sizable first place lead followed by Fedora Server 35 having a measurable lead over the rest. The remaining three distributions -- CentOS Stream, Alma Linux 8.4, and Ubuntu 21.10 -- were aligned close to each-other. Fedora Server 35 was running about 5% faster than the slowest three while Clear Linux was around 16% faster than those three distributions.
