Microsoft and AMD have solved Ryzen performance issues under Windows 11

We recently learnedthat Microsoft and AMD are preparing fixes for the correct running of Ryzens under Windows 11, which were to address both snail latency L3 cache, which caused a particularly slower running of games and then malfunctioning CPPC2 for selecting preferred kernels, ie for assigning single-threaded load to those kernels that are able to reach the highest beats. –

As we also learned, the patches released during the last Patch Tuesday even worsened the latency of the L3 cache, but it was almost ready for the fix that Microsoft came up with, as it is a patch for Windows 11.

The difference shows a comparison of performance in AIDA64, where we can already see the latency of the L3 cache below 10 ns and also much higher performance with regard to writing, reading and copying data.

In other words, problems with the L3 cache will be solved by a patch, so we just need to use the Windows Update function and download the latest update, which we can also do it manually. There is no need to worry that this update is marked as Update Preview, but it is not a beta version, but simply that it is marked as an update offered before the due date of Patch Tuesday. And there is really nothing to wait for, as tests of the new Alder Lake-S are being prepared, which will take place mainly in Windows 11 due to the support of the hybrid architecture of these processors, so this system needs to work as well as possible on competing Ryzens. –

As for the choice of preferred cores, there is a new one AMD Chipset Driver Software 3.10.08.506which comes with Windows 10 and 11 support on boards for older and new Ryzens and Threadrips. However, when it comes to the combination of, for example, 1st generation Ryzen and Windows 11, then of course it is no longer offered just because these processors are not officially supported in Windows 11.
