Arch Linux vs. CachyOS vs. Omarchy 4.5 Performance Benchmarks
With CachyOS recently having rolled out its Linux 7.3 based kernel and various other improvements plus with Omarchy 4.5 having been released this week, this article provides a look at how CachyOS and Omarchy are competing on the performance front relative to upstream Arch Linux.
In a recent comparison, three Linux distributions—Arch Linux, CachyOS, and Omarchy 4.5—were benchmarked on the same Framework Desktop computer. This system featured an AMD Ryzen AI Max+ 395 Strix Halo with 64GB of RAM, integrated Radeon 8060S Graphics, and a 2TB WD_BLACK SN7100 NVMe SSD. All three distributions were installed on a Framework Desktop computer for a fair comparison.
Arch Linux was installed using a generic archinstall setup paired with the KDE Plasma desktop environment. CachyOS, on the other hand, was installed with default settings and subsequently updated. Omarchy 4.5 also followed a stock installation process.
CachyOS operates on Linux 7.3, while both CachyOS and Arch Linux upstream were still on Linux 7.2 at the time of testing. Furthermore, all three systems ran GCC 16.2. Notably, Omarchy defaults to the performance profile out-of-the-box, while both Arch Linux and CachyOS initially defaulted to a balanced performance setting on this particular laptop.
CachyOS stands out by incorporating an array of out-of-the-box optimizations derived from Zen 4+ optimized packages and additional tuning. This marks the first detailed analysis of how Omarchy measures up against Arch Linux and CachyOS in terms of performance.
