Microsoft backports AMD branch prediction improvement to Windows 11 23H2

Microsoft has backported branch prediction optimizations for AMD processors to Windows 11 23H2, allowing users to experience performance improvements without waiting for the upcoming 24H2 update. The update, identified as KB5041587, is available under the optional updates section in Windows Update. AMD has indicated that the performance uplift from this update will be comparable to that expected from the 24H2 update. While some users have reported performance gains in various games, others have noted regressions in specific titles. The optimizations primarily benefit AMD's Zen 3, Zen 4, and Zen 5 CPUs, with particular attention on the Ryzen 9000 series, which has faced criticism for underwhelming performance in gaming compared to competitors. The branch prediction improvements are expected to enhance gaming and productivity workloads for these processors. AMD has described the optimizations as "AMD-specific," raising questions about whether similar enhancements will be available for Intel processors in the future.
