AMD processors hit by performance issues on Windows 11, patch on the way

AMD has said that its CPUs are taking a performance hit on Windows 11 systems and that it has teams working on the issues. Patches should be released later this month through Windows.

AMD: Windows 11 May Cause Performance Dips Of Up To 15% On Ryzen CPUs

AMD reported issues that their Windows 11 compatible AMD Ryze CPUs were having with performance while running certain applications.
wccftech.com wccftech.com

The issue mentioned in the opening paragraph is caused by functional L3 cache latency which has increased by around three times on affected hardware. The programs that will suffer include those sensitive to memory subsystem access times. AMD noted another problem too, explaining that UEFI CPPC2 may not schedule threads on the processor’s fastest core preferentially.


Regarding the latter issue, applications sensitive to the performance of one or a few CPU threads will see a performance hit. The issue will be more noticeable on greater than 8-core processors that operate at over 65W. This issue should also be fixed this month.

hmmmm, whose fault is it this time? It screw up the future hardware review if true? what about Intel side?

Hmm, I'm generally opposed to most conspiracy theories, but.... I would be shocked if this issue is fully resolved by the time Alder Lake is released and hardware sites run their benchmarks and put out their stories... It's going to be a one sentence explainer or a footnote at the bottom of pages at best, and we'll probably see UserBenchmark just run wild with this one...

You have to think that MS and their testers have had representative AMD products on their desks for months by now and this hasn't come up before?!?!

Who would use Win11 RTM as their sole review testing platform? You'd have to disclaim everything as being a potential artefact of Win11's lack of maturity. It would be like reviewing gaming graphics cards but only with one game that was released yesterday.

It would make some sense to have a dual platform (in terms of OS versions) setup, but this scenario works best for MS to show off Win11's improvements.

This is Microsoft fault, but why AMD didnt realised this sooner? everyone has access to the insider builds.

On one hand I can understand AMD thinking, "pre-release product, let's wait till they have something closer to release", on the other hand I'm surprised that they haven't been working with MS prior to RTM.

I dunno dude. This entire OS seems like a rushed release. Heck, the updated paint doesn't even have a dark mode. Let me repeat that. Their own app doesn't support the theme in their own OS. Just crazy.

It's the best to stay away from this garbage for 6-12 months.

It's not even close to being ready if they are finding obvious showstopper bugs 3 days after release...

Clearly, there is no testing / QA done by Microsoft. They just send it out for users to test their code.

Just to joke about Bethesda games and took to calling them Bugsoft as they always released games where their users had to fix all the issues. Just was well TES (and later Fallout) modding took off; and didn't Microsoft recently buy Bethesda?

Maybe Microsoft are going to release a Creators Kit for Windows so users can fix their QA issues?

You should definitely upgrade now if you're cool with a beta OS and don't need your computer for any critical tasks.

It can't be that beta of an OS. It's just Windows 10 with some UI tweaks and a new name so OEMs can push buying new.

I bet they've known about it for awhile, they are just making it public now because of the release. Not sure if this is an AMD specific security hole they are patching or an Intel conspiracy.

Where do you get that this is a security hole? No one said that.

Security hole does not manifest itself typically with a 15% slowdown.

Yep

I really question why you need to release it now? Holiday release / CES 2022 new hardware release?

Bad press will hurt Windows 11 more than 3 months of sales.

Do you really have to ask?

It's not just for today either. The sooner you get it out there, the sooner corps running Skylake and Kaby Lake who don't have a formal refresh process will be compelled to buy new.

"It runs bad on AMD" isn't going to hurt Intel laptop sales.
