There still are several months to go until the official Ubuntu 26.04 LTS release — including one month until the feature freeze and the future Linux 6.20~7.0 kernel is expected to land too before the latter kernel freeze in early April. But for those curious how Ubuntu 26.04 is looking so far for servers, here are some very early benchmarks of it on AMD EPYC 9005 “Turin” in its present development state. The main motivation here for this early look was stemming from the recent rolling-release CachyOS benchmarks on AMD EPYC and wanting to see how it goes up against the current development state of Ubuntu Linux.
Following the recent benchmarks of CachyOS and its upstream Arch Linux tests on an AMD EPYC 9655P 96-core Supermicro server, I turned to seeing how Ubuntu 26.04 is looking in its current — still early — development state. Plus there are the Ubuntu 24.04.3 LTS and Ubuntu 25.10 benchmarks on this same server for reference as well.
At this point in time Ubuntu 26.04 is running on a Linux 6.18 kernel compared to Linux 6.17 in Ubuntu 25.10 or Linux 6.14 right now in Ubuntu 24.04.3 LTS with the HWE stack. Ubuntu 26.04 is using GCC 15.2 like Ubuntu 25.10 and that will stay that way for this release — it’s not until the Ubuntu xx.10 releases where Canonical moves to the next compiler version with GCC 16.1 not debuting until March~April. There have been other package updates to land in the Ubuntu 26.04 archive since October while of course more package updates are expected over the coming weeks.
When Ubuntu 26.04 LTS is in its near final state for the April debut, there will be plenty more benchmarks to come on Phoronix on different desktop / laptop / server platforms. For now the main intent is just an early look relative to Ubuntu 24.04.3 / 25.10 and then the recent comparison against CachyOS.
