Notes: AMD officially lists Windows 11 (64-bit), Windows 10 (64-bit), RHEL x86 64-bit and Ubuntu x86 64-bit. The Ryzen 9000 series is on Microsoft's Windows 11 24H2 and 25H2 supported-processor lists; 26H2 keeps the 25H2 requirements. Windows 11 24H2 includes branch-prediction optimizations that benefit Zen 5. Other mainstream x86-64 distributions such as Fedora and Arch run without special support.
