AMD Watch posted an update
Phoronix is comparing CachyOS, Fedora 45 and Ubuntu 26.10 on an AMD Ryzen 9 9900X3D2. Its test highlights a practical snag for Ubuntu users on this particular setup: the Radeon RX 9070 GRE’s driver stopped the display working at boot, so Phoronix used a workaround to run Ubuntu 26.10.
Why it mattersThat meant graphics tests were left out, so this comparison cannot tell readers which distro performed best in games or other graphics workloads. The reported driver problem is specific to this test system, not evidence of a general Ubuntu failure. A useful reminder that OS benchmarks depend on working drivers as much as headline hardware.
Discuss: Would you trust a distro comparison that omits graphics tests, or is that too large a blind spot?
