CachyOS vs. Fedora 45 vs. Ubuntu 26.10 Performance On AMD Ryzen 9
With the recently released Ubuntu 26.10 and the nearly-released Fedora Workstation 45, Phoronix readers have begun inquiring about fresh benchmarks looking at how they stack up against the performance-optimized, Arch Linux based CachyOS. Up today are our first CachyOS vs. Fedora 45 vs. Ubuntu 26.10 benchmarks on an AMD Ryzen 9 9900X3D2 desktop system.
In a recent performance comparison of Ubuntu 26.10, Fedora Workstation 45, and CachyOS on an AMD Ryzen 9 9900X3D2 desktop system, several key findings emerged. Both Ubuntu 26.10 and CachyOS were running on the Linux 7.3 kernel, whereas Fedora 45 was still on Linux 7.2 but had plans to update to Linux 7.3. The testing utilized Mesa 26.2 graphics drivers across all systems, while Fedora 45 and CachyOS utilized GCC 16.2, while Ubuntu 26.10 was on GCC 15.
The AMD Ryzen 9 9900X3D2 system, equipped with an ASRock X870E Taichi motherboard, 2 x 16GB DDR5-6000 memory, and a WD_BLACK SN8100 NVMe SSD, underwent numerous CPU and system benchmarks to evaluate the competition among the three operating systems.
One challenge faced during the Ubuntu 26.10 test was the Radeon RX 9070 GRE graphics card falling back to using LLVMpipe upon booting, which caused display issues. To resolve this, the 'nomodeset' kernel parameter was implemented to ensure the display would light up. The performance of these operating systems on the system provides valuable insight into their relative strengths and weaknesses in terms of out-of-the-box optimizations.
