Written by Michael Larabel in Computers on 3 January 2022. Page 5 of 5. 8 Comments

188 different tests were run on Pop!_OS 20.04 vs. 21.10 for this System76 Thelio Major. When looking at the tests with a statistically significant difference between the operating systems:

The most dramatic changes in performance were with the Radeon Vulkan/OpenGL tests where the current open-source AMD Linux graphics stack for the Navi hardware is much faster than where it was in early 2020. Aside from the strong graphics driver improvements, the CPU performance for this Zen 2 Threadripper evolved nicely with a number of wins there and only a few cases of lower performance running this latest Linux operating system release.

If taking the geometric mean of all 188 tests incorporating tests across all the subsystems, this workstation is roughly 12% faster than where it was on Linux at launch two years ago.

Dig through all the benchmark results in full via this result file but long story short this Threadripper 3990X + Radeon powered Thelio Major workstation (review unit provided by System76) has matured very nicely over the past two years on Linux and is still running great.
