Latest Linux Hardware Reviews, Open-Source News & Benchmarks

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. Over time more NZXT Kraken AIO coolers have been supported by the Linux kernel and with the upcoming Linux 6.10 kernel the latest NZXT Kraken CPU coolers will be supported.

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. LLVM developers are now weighing whether to deprecate -Ofast to either remove it or have it just be an alias for the -O3 optimizations.

Intel engineers have been reworking Intel CPU model handling for Linux after using "Family 6" since the mid-90's with the P6 micro-architecture and continuing to rev the model ID only with new micro-architectural generations. It's an end of the era for Family 6 coming up and thus there's a lot of Linux patches being worked on to address assumptions within the kernel code that was only checking for an Intel CPU's model ID and not for any family ID differences.
