New Windows 11 Patch Worsens Ryzen L3 Cache Latency, AMD Announces Fix Dates

AMD's "customers" include huge organizations who use Threadripper or EPYC workstations to conduct mission-critical workloads.

I'm pretty sure huge organisations that run critical processes on their systems don't jump onto fresh-out-of-the-oven OS versions. Maybe they will start switching to Win11 a full year from now, at the earliest.

Yes! The company that I'm working in with 10k+ employers, ended windows 7 laptops this year. Now everyone has windows 10. (about f...ing time 😛 )

Exactly. And a lot of them probably use LTSC.

I have to say I'm surprised this is taking so long.

It's probably already fixed, they just don't want to cause yet another regression.

mackintosh:

I don't think there's enough data to conclude who is at fault here. Nevertheless, it lends credence to AMD detractors who profess that unlike Intel, there are always compatibility issues with their chips.

Sure there is. How is this AMD's fault? AMD isn't the one who screwed with the kernel and scheduler without testing. Clearly, AMD wasn't consulted about any such changes, because the last thing they need is to give Intel an advantage.

Microsoft really needs to reorganize the Windows team, and get the quality testers back. They can't continue to release broken update, after broken update, and expect users to be the beta testers.

Why not? It´s not like their customers are fleeing to other OSes like Linux or MacOS. That´s the problem with monopolies, they can do all sorts of crap that their customers won´t do anything because of the lack of choices... Another example is Android...

Whelp. Just set Win 11 not to install any updates for 14 days. Glad I turn off automatic updating as one of the first thinks I do when I install a fresh OS. Microsoft will eventually get their Sh*t straight. Guess I will call my friend at AMD and get a copy of the current lab drivers with the current fixes. May just revert back to Win 10 if Microsoft does not fix it in a reasonable time frame. Do not have much time for gaming right now so my main gaming rig with Win 11 on it is not a priority. Intel is having its own set of issues with Win 11 too.

LOL and one of my friend with a 5900x upgraded to win 11 after I told him about the issue with Ryzen. I'm on 5800x and will stick to windows 10 in the mean time.

Honestly we all should be on Windows 10 for another 6 months to a year. Its obviously in early beta. Let the uninformed beta test it.

And miss out on the sweetness that is Auto HDR? No, I will deal with the minor issues to get the features, thanks, and leave my work machine on the safe path. The bleeding edge always cuts a little bit.

Our company (6000+ employees) is considered by MS to be a "premier partner", and it took us over 2 years before we started rolling out Win10. We only a couple months ago started mandating new servers be built on Server 2019 (although we have had a few around for over a year that wanted to give it a go), and Server 2022 is about to launch. The enterprise world moves very slowly and cautiously with this stuff. On the other side, we are on the fastest path possible for Teams rollouts. We usually have the features you read about in the news a month or so after they report on it, which if you think about the above is kinda terrifying. I mean, we have spent the last month doing meetings about rolling out a firmware update from 2 years ago for our servers that fixes a bug we have actually been impacted by and has caused downtime to make sure it's properly tested, but we have Teams running the latest build pretty much as soon as it hits Azure. The difference? The CEO and CTO use Teams and want the new hotness.

Agreed. There are some other things, too--also the L3 slowdown will be remedied by Microsoft's CPU drivers soon, as already mentioned. Main thing is the slow-down doesn't come close to "hobbling" my games...;) Anyway--the takeaway for me is that Win11 is where the OS R&D will be spent while Win10, which I have enjoyed, now takes a backseat. Plus...I'm on 22471.1000, too, which is several builds in advance of the current Win11 builds (22000.xxxx) released to the masses, and some of the fixes I'm seeing haven't yet trickled down to the 22000 builds as of yet. Yes, Win11 is not for the delicate and fainthearted...;)...but also it is nothing at all like the jump from Win7 to Win8...which was horrific, imo...! Win11 runs and feels just like it's built right on top of Win10 build 21390...the last and best build of Win10, imo--but unfortunately, the 21370-90 Win10 beta builds will not make it into the supported Win10 versions now--Microsoft put all of those advances (including AutoHDR) into Win11.

Agreed as well. People don't get what a big deal AutoHDR really is - when was the last time an update came along that seamlessly and noticeably improves the graphics quality on pretty much every game you play? Let alone one that does so with no perceptible performance hit. It moves an HDR monitor up the list from "things you might want" to "things you really should have", and if you have one already is definitely worth the pains of running Win11 (and there most definitely are pains) to get it. Once DirectStorage starts being implemented, it's going to dramatically change PC gaming as well, but that one is still a bit down the road as games are written to take advantage of it - so it's time to start saving up for that big PCIe 4.0 NVMe drive.

Question is, will he even notice the max fps difference? I don't really notice any performance regression in games, web surfing, DAW recording or other tasks that I use my PC for, so the issue might be a bit overblown when it comes to regular usage.

discovered shortly after release : Says it all.... things like that have to be discovered before you release. Anything else is all just wordgames from idiot marketeers. I just did a bench on my old i7-3770. It appears to be the fastest i7-3770 at stock speeds with the fastest vega 64 xt at stock speeds .... in the world , at this time. Still getting above the 50% of all benchmarks that futuremark has. so there is absolutly no need to upgrade anything yet. And i sure don't have problems like AMD now has with windows 11, just a matter of avoiden all the manipulations, they did that in the past with the old systems and now they quit that and do it on the new ones, it's a matter of giving people false ideas they need new hardware, when it's all created bugs and pestering for profits. And yeah that is easy to do and hard to prove for anyone, so you can be damn sure they do it. And windows 11 is just a crappy windows 10. same engine, lots of stuff to configure you can't find anymore, and ofcourse the dinkytoy (Apple) user interface again.

Sounds like someone spends a lot of time justifying their out of date hardware. Look, I'll help - it's OK to have an old PC, as long as it does what you want it to do. If playing games at 720p on medium settings is enough for you, then you don't need to worry about it.

Microsoft was well aware of this issue before it was even called windows 11, they just didn't care.

People seem to forget in what kinda state windows 10 was released back in the day.

People seem to have a really short memory.

No windows version has ever been released without major issues. Hell, the final release of WinXP was less stable than Beta 2..... Actually took a service pack to fix most of it's bugs. However, people still ramble endlessly about how great XP was. For a lot of us that were on the beta team, the launch of XP was actually a disappointment, seeing how unstable it was. Hell, XP launched with bugs still present that had been reported during Beta 1....

insp1re2600:

Pretty obvious that he hasn't been around long.... At one time, people had to actually apply for the Windows Beta team. The insider program was supposed to improve quality, but MS still refuses to read and address bug reports adequately. I actually miss the days of the Windows Beta teams.... I got a free copy of OfficeXP from that.....

After the past few years on Windows insiders builds I've moved back to Linux (Ubuntu-Budgie) as my main OS… funny, I don't even have a windows install on my desktop at the moment. Insiders channel was completely broken for me, was ahead of the release version, v11 want great when it did work. WSLg want enough to keep me. I may put Windows 10 on a different drive if I need it, but would rather get stuff done for now, and windows no longer gives me that.

This. Microsoft's new OS releases usually need some big patches to get them up to scratch. Win 98 2nd ed, XP sp1 patch and so forth
