Maybe there are some "Branch Prediction Optimization": https://wccftech.com/amd-branch-prediction-optimization-ryzen-9000-7000-cpus-available-windows-11-23h2/ https://wccftech.com/amd-ryzen-9000-gaming-performance-update-revised-testing-parity-intel-14th-gen-cpus-optimized-branch-prediction-boost/

I took some time today to resolve the compilation issues in Visual Studio 2022. After running some tests, I found that the results for 2200 and 1400 were not significantly different(with Windows KB5041587 update). btw, Which tests overflow the uop-cache?

Thanks for your reply. I download the version 2200, but I don't know how to build it. I have try nmake -f CPP/Build.mak, but get error: nmake -f build.mak Microsoft (R) Program Maintenance Utility Version 14.40.33813.0 Copyright (C) Microsoft Corporation.
