AMD said its processors may experience performance degradation in Windows 11, up to a maximum of 15%

AMD said that when a processor that meets the requirements of Windows 11 is in use, performance may be reduced in some applications. In some e-sports games, there is even an extreme decrease of 10%-15%. Under normal circumstances, the impact is about 3%-5%. AMD is currently working with Microsoft to resolve these issues, and it is expected that the update and optimization of both parties will be launched within the month.

AMD made a relevant explanation for this performance degradation. The problem is mainly due to two aspects. One type is that the latency of L3 may increase three times, causing some applications that are sensitive to memory and cache to be affected. Games are one of them. The other category is the “Preferred Core” function, which means that threads are allocated to the two fastest cores, but it may not work as planned in Windows 11. This performance degradation is most pronounced in processors with 8 or more cores and a TDP of 65W or higher.

AMD recommends that users who are more affected “continue to use Windows 10” and wait for AMD and Microsoft to investigate specific issues and resolve them through software updates. This means that it may not be a wise choice to upgrade the AMD platform to Windows 11 before solving the problem. These issues are separate from the performance issues of the VBS and HVCI security settings recommended by Microsoft before, and these issues have caused dissatisfaction among some users.
