Ryzen 9000 performance benchmarks anomaly explained

Automated test suites run with Super Admin privileges for legit reasons and AMD overlooked how this would affect performance due to some branch prediction optimization options not yet supported in normal operations. Fix will come with a upcoming Windows patch later this year.

Nice. Glad it’s “just” a software (Windows patch) fix.

PC users will be able to tap into those performance improvements when Windows 11’s annual feature update, dubbed “24H2” for now, starts to roll out later this year – its branch prediction optimizations mimic the Super Admin changes AMD tested with. (The always-excellent Wendell of Level1Techs already has a nice and nerdy analysis video about the patch, which is available to Windows 11 Insider preview testers.)

Update: Hardware Unboxed tested the Ryzen 7 9700X across 40 games with Windows 11 24H2 preview installed and found truly massive gaming gains — an average of 10 percent over the performance of the current Windows build, with several games running 20 percent faster and a handful hitting blistering 30 percent performance improvements. It’s a truly wild, jaw-dropping performance improvement for an operating system upgrade.
