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

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?

dows W11 do anything IRL better than W10 ?

It will definitely annoy people better than Windows 10 with its UI changes. Microsoft missed the chance to design an attractive guided tour introducing the new features and changes to existing users. That would have prevented the swearing that will surely ensue as people try to adapt to the new way of doing things.

 

[jpiniero]

.. and some won't.

I imagine any W10 Home machine that is supported in W11 will get force upgraded. Which you would think would include any recent laptop that didn't turn secure boot off.

 

[Thibsie]

Well my W10 PC shows only one update possible, awaiting for me accepting licensing terms : Win11 of course.
Not that I was asked if I had any interest, of course.

Windows 11 Home requires an online account to work. Not sure if a forced upgrade with local account would force the user to create an online account to use Windows 11 Home.

How to Install Windows 11 Home With a Local Account - ExtremeTech

Neowin forum member warwagon has created a video illustrating how Windows 11 Home users can still create a local account at startup without being forced to use a Microsoft email. When you see the “Let’s connect you to a network” screen, hit Shift-F10, type “taskmgr” in the command prompt window, and kill the process called “Network connection flow.” According to the video, this will allow the OS to install normally after you insert a user login and password. You can also kill the application directly from the command line if you like, using the command “taskkill /F /IM oobenetworkconnectionflow.exe”

That's annoying.

Windows 11 is really nothing more than a feature release of Windows 10. Consumers are going to be forced upgraded eventually anyway.

I have been reading a guide about how to disable tpm 2.0 in bios
Currently set to tpm 1.2 so Windows update don't think my hardware support win11 until I'm ready to make the swap myself.

Clever, unless Windows Update checks for supported CPU model only and presents the Windows 11 update.

It is annoying, but it literally takes 1-2 mins and is super easy to do. I never use an online account with my installs. At least there is still a way to avoid it.

 

[LikeLinus]

It is about Windows 10, because it is the baseline. If you can't even get to the baseline, then you don't ship.

That's ridiculous and doesn't even make sense. Ever OS release is going to have bugs or things that don't function correctly. You can have something as a baseline, but then you edit millions of lines of code, while support tens of thousands of pieces of hardware, and you think everything should be 100% or not released at all? Buddy, news for you, you would never have new software.

 

[DigDog]

just to be clear .. in case i wasn't suuuuper clear earlier - i do not approve of, or condone, Microsoft's behaviour in the last (basically always) years.

I do however also blame ourselves, because - as it was made clear to you all previously - this state of affairs is a direct consequence of making computers "user friendly" and removing the need to be an informed user and a critical thinker, that happened throughout the late 90s ... mostly due to Apple, but also due to M$ following in their tracks of replacing "users" with "consumers".

The problem is that M$ does this **** and there is zero uproar from the userbase. Cortana stealing data ? Nobody cares. W10 mandatory upgrades? Nobody cares.
Yeah ok so maybe the occasional article in semi-pro publications, but nothing at roots level, no mass boycott, no retaliation.

The user world used to be very different in the 80s and 90s.

So, i will not be affected by this, but other people will. There *will* be stories of School Locked Out Of Own Systems By Upgrade, or Hospital Loses Records Due To Disk Security, or some BS like that, and the longer this goes on, the more we lose our user rights - the right to owership of a purchased product.

All fixed up. Stock 5950x. Numbers may be a bit off due to stuff running in background and crap RAM.

I am on the Windows 11 Release Preview channel.

Any idea what happens if the machine doesn't have recognised network hardware yet? e.g. Win11 doesn't have a driver for the network hardware?

Windows 11 is really nothing more than a feature release of Windows 10. Consumers are going to be forced upgraded eventually anyway.

From what we know about Windows 11, it would be insane to install it now for a work computer. But in 6-12 months, it should be ok.

Going on the limb with majority of machines on Windows 11 seems like an unnecessary risk for Dell...

Most of the Windows 11 is Windows 10 (and all the way back to Windows XP etc).

Pretty simple way to deal with the few features that don't work.

Hold back the new feature or hold back the release date of the of the OS.

Microsoft set itself up for failure by agreeing to an impossible schedule, and predictably Windows 11 is seen as a fail. It could have been a success if Microsoft gave it a more customary development + alpha + beta times.

LOL. It's a failure? It's been out for a week and half and a free upgrade. Not to mention this only affects AMD CPUs (the scheduler, the UEF
I driver is their fault) which is around 20-30% of the overall market. Its effects are really only noticed by people who are enthusiast; an even smaller segment of the market. That's why you only see this being reported on by tech web sites. Joe Public doesn't know about this or care about it.

Plus, what agreement did MS make to a schedule? Link? I haven't read anything that says Microsoft was doing this to some agreed schedule. Most likely they were trying to get this in the hands of OEMs in time for the holidays and release of their new line of Surface products. A fix is already rolling out and this isn't really a big deal.

If you don't like MS or Windows, use Mac or Linux. I use both Mac and Windows. All OSs have some issues when initially launched. This is from 2 weeks ago when the Big Sur update came out.

"Some Mac users are noticing a big difference after moving their computer up from the previous version of macOS Big Sur, macOS Big Sur 11.5.2.

On the flip side, some Mac users have run into bugs and performance issues. Some of these issues have carried over from macOS Big Sur 11.5.2, others are brand new."

"The macOS Big Sur update is also bricking some older MacBook models. The problems appear fairly widespread and they’re mostly impacting owners of 2013 MacBook Pro and mid-2014 MacBook Pro models."

Would you rather Win 11 be bricking your laptop? Point is, this is common and you apparently must be new to the computer world.

heh. I guess it'll skip that step like WIn10 does, and I hate being right about Windows going in a direction that I predicted (requiring MS accounts for sign-in) it would and didn't want it to (hence I run Linux since Win7 EOS), it still surprises me a bit though because I would have thought that MS's Win10 strategy of being a pain in the ass to people not running with an MS account would have worked well enough.

 

[DrMrLordX]

Debatable. If I knew I had a fix in the pipeline (MS does; it's worked its way into the beta and release preview channels), then I might launch anyway and just let the AMD fans stew for a bit; that being said, annoying "20-30% of the market", a percentage of the market that enjoys (and on Win10, continues to enjoy) a performance lead over the competition, seems like a bad PR move. The Win11 release window has been pretty odd all around. Win8 and Win10 were not handled in this manner. Win10 certainly wasn't.

The point still stand and LikeLinus is glancing right over it. "only 20-30% of the market" ... so that makes it right? The whole Microsoft Enterprise didn't have $500 for purchasing an AMD CPU during the development of Windows IE (Intel Edition of course)? Are you living in a cave or what, @LikeLinus ?

Today no one can force a "well-informed user" to do any Windows upgrade or update.

In Windows 10 There is no option to turn off Windows Updates. Windows Update Blocker is a tool that helps you to completely disable or enable Automatic Updates.

It doesn't work like that, ZEN 3 has a multiple layers of cache and a cache controller, if any of that uses AMD IP then MS can't just use it even if it is easy for them to figure it out they don't have the legal right to do so.
Look at all of this, it's all over the place and each of that could have something under copyright making it impossible for MS to do anything without AMD.

Rocket lake just has one simple cache per core, there is nothing to do wrong there.

Fixes for AMD Ryzen performance, other Windows 11 issues rolling out to testers now | Ars Technica

Other bugs addressed in the Windows 11 update include one that prevented some upgraders from seeing the new Taskbar or using the Start menu, a PowerShell bug that can fill up a storage volume with "an infinite number of child directories" when you try to move a directory into its own child directory, and a number of problems that could cause freezes, crashes, and slowdowns.

I'm glad that I didn't have to worry about that!

From the comments:

It took an awful long time to install though, it waited for 45 minutes before i just rebooted it, then the desktop came back without explorer.exe running and no taskbar. Another reboot seemed to have sobered up Windows 11 again though.

Ugghh. Likely rushed through QC testing.

By the way, some of the bug descriptions make me think that they have interns coding for them.
