AMD has published an advisory warning early Windows 11 adopters that they may see performance degradation in various applications with select, compatible AMD processors.

One of the biggest impacts relates to gaming; AMD says that certain eSports titles may see reduced performance of up to 15 percent. Performance impacts of 3 to 5 percent have also been noted for select applications.

The performance variation in Windows 11 when running compatible AMD Processors is owed to potential increases in L3 cache latency, which may increase by up 3x. AMD hasn’t elaborated on the reason for this but has promised that it is working with Microsoft on a fix that is scheduled for release this month.

Per AMD:

AMD and Microsoft are actively investigating these known issues for resolution via software updates. This knowledge base article will be updated to include version numbers and delivery vehicle(s) when they are available. In the interim, customers using compatible AMD processors affected by these issues may continue to use a supported version of Windows 10.

AMD’s table also warns of an issue in which threads may not be scheduled properly, resulting in reduced performance in select applications. The degradation is more likely to be detected in processors with more than 8 cores and TDP of over 65 watts.
