the way is finally clear for AMD Ryzen users!

Windows and AMD have finally rolled out the necessary fixes to resolve compatibility issues between the new OS and Ryzen CPUs.

Since the beginning of October, we have already told you several times about the performance concerns encountered by some users of Ryzen processors under Windows 11. Microsoft and AMD have finally rolled up their sleeves to tackle the bugs, which should normally be resolved.

As a reminder, there were two main ones. The first concerned the latency of the L3 cache, which had more or less tripled for no apparent reason. The second concerned a problem with the distribution of the load on the different cores of the processor. Put together, these two bugs could significantly slow down the new operating system; the various benchmarks spoke of performance 3 to 15% lower.

AMD has issued a press release reporting several updates. These should normally resolve these compatibility concerns. To begin with, Microsoft took charge of the cache part in a software update available since yesterday. In the update documentation KB5006746 (build 22000.282), we can read that she “Resolves an issue with the L3 cache that could affect performance on devices with AMD Ryzen processors after upgrading to Windows 11”.

For the load distribution side, AMD took care of it with a patch of its driver. The latest version of its Amd Ryzen Chipset Driver (3.10.08.506) should therefore finish resolving these compatibility issues. On the official patchnote, we can read that she “restores the expected function and behavior of UEFI CPPC2 (“preffered core”) in Windows 11 build 22000.189 or newer”.

Users with AMD Ryzen processors will finally be able to taste the new OS without sacrificing performance.

How to install these fixes?

To benefit from these fixes, it’s very simple. First, you just need to check the updates to your machine; you should have access to new Windows build, which will solve the distribution problem. For cache latency, you can download the driver from AMD’s patchnote, or directly here. The process is very simple, but if you have any doubts, everything is explained step by step on this page.

Note, however, that there are still some older Ryzen CPUs that are not supported under Windows 11. This particularly concerns the first generation of Ryzen, including the Threadrippers. The full list is available on the patchnote. But all in all, there is finally something to smile about for users with AMD processors. This means that it’s finally possible to upgrade to Windows 11 without having to compromise on performance. Not too soon !
