As noted at the end of March, System76's Pop!_OS Linux distribution has upgraded to the Linux 6.8 kernel as a stable release update for this Ubuntu-derived distribution. That Linux 6.6 to 6.8 leap on Pop!_OS yielded some nice kernel performance improvements for the AMD Ryzen Threadripper 7980X available with their newest System76 Thelio Major workstations. But tests I've carried out of the Pop!_OS upgrade on a years older System76 Thelio is showing off some nice advantages too.

With the recently released Ubuntu 24.04 LTS I've shown various benchmarks how it can deliver nice performance gains over both Ubuntu 23.10 and the existing Ubuntu 22.04 LTS on different platforms. Those benchmarks have tended to focus on the latest-generation processors/platforms given that's where the excitement is these days. But for those on older platforms like AMD 3rd Gen EPYC "Milan" servers, here are some benchmarks looking at the performance impact of an Ubuntu 24.04 LTS upgrade...

Merged back in 2021 with Linux 5.13 was an NZXT Kraken hardware monitoring "HWMON" driver to support sensor monitoring of these all-in-one liquid cooling products from NZXT.

Some that crave the absolute best possible performance sometimes build their software with the "-Ofast" optimization level that is a step above "-O3" but comes with the risk of potentially unsafe math.

Intel motherboard manufacturers have begun rolling out BIOS updates containing an "Intel Baseline Profile" option to apply stock power limits to modern Intel processors. This is being driven by instability claims for 13th Gen and 14th Gen Intel Core processors having stability issues for some Windows gamers that is being attributed to multi-core enhancement (MCE) and other power options commonly set on enthusiast desktop motherboards. As the first of several ongoing tests I'm working on at Phoronix, here are some preliminary findings for using the Intel Baseline Profile option on an ASUS motherboard with the Core i9 14900K under Ubuntu Linux.
