Patches Planned for AMD Processor Slowdown in Windows 11

Both AMD and Microsoft plan to roll out fixes for the issue later this month

Some AMD processors have started performing sub-optimally with Windows 11 installed, but both AMD and Microsoft are working on fixing the problem.

AMD has released a report stating that some of its processors have been experiencing performance issues with Windows 11. Specifically, running certain (unspecified) applications can see processor speeds drop up to 5%—or up to 15% in some games. This is caused by either the processor's cache suddenly taking up to three times as long to access or some tasks being mistakenly handed off to a slower processor core.

The report goes on to state that any of its Windows 11-compatible processors could be affected. These performance dips only happen when certain programs and games are being used, so some users may never experience any issues.

It might be tricky for some users to avoid, however, as AMD points out that "games commonly used for eSports" could experience processor slowdown.

If you're using both Windows 11 and an AMD processor, and you experience performance drops with some software, your best bet, for now, is to just not open that software.

If you have an AMD processor and haven't upgraded to Windows 11 yet, AMD suggests holding off for the time being and using Windows 10 instead.

Both AMD and Microsoft already are working together to patch the problems. AMD's fixes for both the cache latency and task preference issues should start rolling out later this month.
