complain to hardware vendors as they responsible for optimizing this in driver/firmware for OS vendors too lazy or just want to sell new hardware and not fix or optimize older hardware too much
let's never again downplaying other people's issues (with reproducible proofs!), as if acknowledging it would make your hardware bad or something I'm so glad it's acknowledged fairly quickly and microsoft will offer a fix as early as this month edit: extra dandruff removed
Except the L3 cache issue is a Windows kernel issue it seems, not driver or AGESA issue. The CPPC issue might be partially an AMD issue though based on the wording in AMDs advisory, although that also seems improved in the dev builds from what I hear. In short, Microsoft deserves the blame on this one.
yeah on engadget amd is working on a fix for windows 11 as they see performance hits and don't want their name/reputation tied to anything performance related on a negative so if is amd specifically for this L3 then not my cup of tea as I have always worked with intel based laptops/desktops; but then again is a driver/bios/firmware issue as amd fix will be just that just like intel has many updates/fixes for their hardware; Microsoft makes products that take advantage of certain things over time but never leading/bleeding edge for the most part as that is on the hardware makers themselves to optimize if their users want to make use of or experiment with just like overclocking and bypassing thresh holds based on not harming the hardware lifespan with extreme usage short term
L3 has been fixed since early last month on Dev builds. The issue is purely Microsoft's fault. They know the fix, but decided not to have it in Release/RTM.
Not sure if m$ decided to go ahead and left out the fix due to shorten time frame left to test before releasing win11. They could push back the win11 release but high chance is they don't really perceive it as a deal breaker for AMD users.
Win11 is already released, so, kinda too late for pushing back release. They will probably block upgrades for Ryzen machines until the fix is available.
Yeah likely the upgrade for Ryzen machine could be after the patch have been release, then there will be a refresh win11 iso.
I would cancel Windows 11 and do a clean install of 10 if I didn't already know there's supposed to be a fix for it this month. Since my performance isn't noticeably suffering I'm going to just wait.
As far as I know, the current 22000 scheduler has problems with Ryzen CPUs. So, if you had any load on your CPU while you did the second test, maybe AIDA showed better scores. I have seen benchmarks running in a W11 VM under Windows 11 showing normal results, while the host showed those awful low results. But this all does not matter, a fix is in the works. So just be patient. I have no apps where I see a significant impact of a low L3 cache performance.
