Ubuntu 25.04 Boosting AMD EPYC 9005 Performance Even Higher: ~14% Faster Than Ubuntu 24.04 LTS

Phoronix - 7. Duben 2025 - 16:19
At the end of March with the Ubuntu 25.04 beta release I began running Ubuntu 25.04 benchmarks on desktop hardware and finding some nice performance improvements thanks to the fresh Linux 6.14 kernel and other new software updates found in this next Ubuntu release.

As the first of a lot more Ubuntu 25.04 server benchmarks to come, today is a first look at the Ubuntu 25.04 beta performance on AMD EPYC 9005 compared to Ubuntu 24.10 and the Ubuntu 24.04 LTS releases.
