Windows 11 began rolling out this week after just over three months of public testing with Windows Insiders. Although the operating system launched with a few known issues, it looks like one of them may have gone unnoticed. AMD has confirmed that its processors are adversely affected by the upgrade from Windows 11, resulting in reduced performance in some situations. Fortunately, the resolutions are already underway.
AMD reports two separate issues with its processors and Windows 11. The first is related to the L3 cache latency on its processors, which can be up to three times higher on Windows 11. This will particularly affect the performance of applications which may depend access time to the memory subsystem, including some fast esports titles. AMD states that performance can be as high as 15% in very specific games, but generally the performance impact ranges between 3% and 5%.
For this one, AMD says a fix will arrive in the Windows 11 update later this month, likely with next week’s Patch Tuesday updates. This will be the first cumulative update for Windows 11 since its general availability, so we should see plenty of bugfixes rolling out alongside this one.
The other issue is the “preferred core” feature in UEFI systems which does not schedule tasks for the fastest core available in a given scenario. This could affect the performance of applications that rely primarily on single or a few cores, as multithreaded tasks would use all available cores anyway. As such, the performance impact may be greatest in processors with a high number of cores and threads, especially those with a TDP of 65W or more. AMD doesn’t explicitly say how big the performance impact can be.
Anyway, a fix is also in progress for this issue. AMD says it will arrive via a “software update”, not a Windows update, so it may come as a new driver version for Windows 11. This patch is also expected this month .
Windows 11 is rolling out gradually, and it’s likely that many users haven’t upgraded yet, so that shouldn’t be a big deal. It’s not uncommon for issues to arise after major new updates like this, and at least one fix is coming relatively quickly. We’ve also heard of an issue with virtualization-based security potentially affecting gaming performance, which is currently under investigation by Microsoft. If you haven’t already, read your Windows 11 review to see why we recommend the upgrade for anyone using Windows 10.
