Microsoft fixed an AMD Ryzen L3 caching issue on Windows 11
After Microsoft officially pushed Windows 11, AMD issued an announcement that when its processors that meet the requirements of Windows 11 are 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 said that it is 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.
Recently, Microsoft announced that it will release Microsoft Windows 11 Build 22000.282 to Windows Insider members of the Beta and Release Preview channels. This version involves a number of improvements, including fixing the latency issue of the L3 cache on AMD Ryzen series processors. However, this does not mean that the problems encountered by the Ryzen series processors on Windows 11 have been solved. The L3 cache delay problem is only one of them, and there is also the problem of the “preferred core” function.
The “preferred core” function means that in AMD Ryzen series processors, threads are allocated to the two fastest cores, but in Windows 11 it may not work as planned. In this case, the performance degradation is most obvious in processors with 8 or more cores and a TDP of 65W or higher. AMD has stated that it will release a separate update at the end of October to resolve.
