News AMD: Windows 11 Slows CPUs Up To 15%, Patch Coming

[eye4bear]

Windows 11 has been in beta testing for many months, with 10s of thousands of insider users which I am sure is a mix of both AMD and Intel chips. How was this not a known issue during the insider testing?

to the whole its a minor issue.

most use cases wont get a meaning issue. So they can fix it post launch.

not really but will wait and see, up to 15% is so big that some will buy a 5% faster processor for more than 100$ extra, with the coming lunch of Alder Lake this could mislead people about the value of ZEN and Alder Lake, and even ZEN 3 may look slower than intel 10th & 11th, sure you mean minor for anyone running a ZEN system and could wait but for someone want to buy a new platform if they not a ware of the problem they will not consider ZEN as a good option, I'm only talking if this was the truth so I'm waiting on a review to deeply compare windows 10 & 11 performance on AMD and intel on every generation supported by windows 11, if AMD telling the truth then it's so much worse than you think, yes I know and I will wait and so do you.. but not everyone, it's already spread around the internet how alder lake is "much" faster than ZEN 3, which is deferent than winning a good fight, if the fix came after Alder lake review then it's an event to remember

Either:

• The scheduler was one of the last things that got pushed out before RTM
• People thought "well it's in beta, so it's probably not a problem"

it's already spread around the internet how alder lake is "much" faster than ZEN 3,

as it should......zen 3 was rival to 11th gen.

zen 4 will be rival to 12th gen. (and given how upcoming zen3 updated chips can net you large performance increase theres no reason to doubt zen4 wont be a great chip line)

if AMD telling the truth then it's so much worse than you think

doubtful.
WIN11 is changing way stuff is done and likely just a conflict somewhere and within month prolly be fixed. (most new WIN versions have issues with performance somewhere such is early adopters risk)

 

[jkflipflop98]

They don't need to speed up Win 11. Much easier to slow down Win 10 in the next update. Oh, the joys of monopoly!
The only solution is to split up Microsoft, Apple, Facebook, Amazon, and all other companies, including those from cosmetics, energy, health sectors, having a disproportionate share in any market.

Can't tell if serious or braindead?

The windows 11 team doesn't even know what a functional GUI looks like, which is crazy considering they have a half-dozen (well, more like 3) decent versions of Windows to use as a reference.
Can you really expect them to be able to code a scheduler when they still can't even figure out button placement, menu layout, or why Windows 8 was unusable?
At this point, they've been actively trying to remove the control panel for over 5 years... but they haven't even successfully copied that basic feature into a semi-functional settings menu. You would think that, at some point, they would have realized that the control panel is fine, and also that Windows doesn't need to compete with iOS.

You are misquoting me, it should does not mean it will, intel core 11th was "it should" but did not, AMD FX was "it should" but was never, if you think false information can go away after correction then you don't know what the internet is,

What I said is ( it's already spread around the internet how alder lake is "much" faster than ZEN 3, which is deferent than winning a good fight)

Yes the truth is I predict a win in ST for Alder Lake and loss in "most" but not all MT benchmarks to every ZEN 3 that have the same core count, this is just a guess but not every reader will take a full review with grain of salt and wait for the fix to reread, and how many will be ready for a rereview, it will be too late for some so windows 11 should wait and a patch should be out before Alder lake lunch, if not then it's going to be a mess

doubtful.

I know that, the problem is the conflict with Alder lake launch, and on that argument, in the past, the newer architecture is the one to have that problem but now it is not, I know it's maybe due MS work with intel on intel thread director, never the less because of the lunch of Alder Lake, older processors should not look too bad "unfairly" for the costumers and the competitor good, for any one else everything is good.

The L3 cache issue has been known since early in the public beta process. Here is a link to users reporting the problem back in July.

For some reason, neither AMD or MS have acknowledged the issue until now. They've known about this for a while as it is already patched in developers builds of Win11.

And I'm wondering why that patch still not coming to this final version yet, if it exists.

Issues this low level on a system this complex take time to make sure that you aren't going to play whack-a-mole with bugs.

The bug is present and solved, but not on official version. Doesn't make any sense to me.
Just my 2 cents.

Here's an analogy. Say an airliner found a crack in the body of a plane. It's fixable so they go ahead and patch it. Would you feel comfortable if they didn't do a series of tests to make sure the patch actually holds and put the plane back into service right away?

Granted lives aren't at stake here, but again, when you have something this low level in a system as complex as Windows, you kinda want to make sure the "fix" is actually a fix.

Because Control Panel is horribly outdated. Stuff like the Network and Sharing Center still looks and feels like its from Win95.

I would rather not fly with that crack, because we are flying with it. What an analogy......

Then let me add: The crack was found during a routine inspection, which implies the plane was flying with it before.

But I mean, if you want to throw out a fix in software without thoroughly testing what it might affect, by all means, be that software developer. I'm sure everything will be fine. 😉

I think they don’t understand how software gets tested before it gets released

In this case the crack was found even before the flight and that's the problem. The dev release that i'm talking about, was release before the original release and it doesn't have the bug.

I don't know if you are talking to me, but if you are, you're wrong 😉
How can MS launch a oficial release with a known bug that was solved in the DEV release launched before the official release? To me, it makes no sense. But that's my opinion, and I'm not the lord of the true

 

[Deleted member 14196]

It was left out of the official release for reasons you may not understand

You do? If so, please let me know, I would like to get my knowledge richer.

 

[Sleepy_Hollowed]

Well, it’s not like if I’m touching this OS at least until 2024.

The current release has serious UEFI issues on my machines which has zero issues on first boot, but then fails on subsequent reboots, it just says there’s a problem with a windows install.
I can make it boot one time with third party tools fixing boot parameters or manually doing so with the install disk, but that’s not something I want to do every boot.

 

[mdd1963]

Epyc owners also affected?

I'd honestly wonder just how many Epyc owners were running a Win11 installation....!

I've got a laptop with an AMD 3020e and since the last updates that it getting slower and slower, do you guys notice the same thing?
