14 DAY TRIAL // The rollout of Windows 11 has come with several important performance problems, including one hitting AMD Ryzen processors and apparently experiencing a noticeable slowdown overall.
Needless to say, this was quite a major shortcoming for some, especially since some AMD Ryzen CPUs should be able to run Windows 11 just flawlessly. And this is the reason Microsoft has been working around the clock on dealing with the whole thing, and a fix is already being available in the latest patch.
Windows 11 update KB5006746, shipped as build 22000.282 to Windows insiders in the Beta and Release Preview channels come with a dedicated fix aimed at Ryzen processors, with Microsoft explaining the following in the official release notes:
“We fixed an L3 caching issue that might affect performance in some applications on devices that have AMD Ryzen processors after upgrading to Windows 11 (original release).”
The fix does its job
The early benchmarks have indeed revealed an important performance increase for Ryzen-powered devices, and now AIDA64 confirms this is really the case, as the performance problems of AMD’s processors on Windows 11 are gone.
“We've installed and tested the upcoming @Windows patch (KB5006746) and it seems that it fixes the L3 speed issue that affected the @AMD Ryzen processors on the initial release of Windows 11,” AIDA64 tweeted earlier this week.
Screenshots included in the tweet also show a noticeable increase in the L3 cache, indicating that the issue is indeed fixed for Ryzen processors.
The Windows 11 rollout is currently under way, and bugs like this one are the living proof that using a release in stages is the right approach for Microsoft in the short term. This release model allows the company to find new bugs in an early stage before more computers are impacted, giving everybody more time to act accordingly and even suspend the rollout for the impacted configurations.
