Company says updates to address the whole thing are coming

Windows 11 is now available for everybody, but if you installed the new operating system on an AMD system and noticed a substantial slowdown in performance, then it’s worth knowing the company itself is aware of the whole thing and fixes are coming.

AMD says in a tech support document that some of the computers equipped with compatible AMD processors could end up experiencing reduced performance in certain applications when running Windows 11 due to two different problems.

First of all, AMD says, the measured and functional L3 cache latency could increase by approximately three times, AMD says.

“Applications sensitive to memory subsystem access time may be impacted. Expected performance impact of 3-5% in affected applications, 10-15% outliers possible in games commonly used for eSports,” the company explains.

The good news is a fix is already on its way, and it should be released to users as part of a Windows update going live this month.

The second glitch concerns UEFI CPPC2, which may not preferentially schedule threads on a processor’s fastest core.

“Applications sensitive to the performance of one or a few CPU threads may exhibit reduced performance. Performance impact may be more detectable in >8-core processors above 65W TDP,” AMD says.

A software update to resolve the whole thing is also coming for users this month, though in this case, it won’t be included in the Windows rollout.

Keep in mind Windows 11 is currently rolling out to devices out there, so in case something goes wrong, there’s a chance Microsoft suspends the release for your configuration. These are called safeguard holds, and Microsoft users them specifically to prevent a certain bug from hitting a larger number of devices.

At this point, however, only three such issues have already been acknowledged.
