Bad news, AMD fans: This week's Windows 11 update didn't fix your performance woes (they may be worse)

It wasn't the news AMD fangirls and fanboys were hoping for. After [1]AMD noted performance issues with Microsoft's latest operating system, a fix had been expected to drop during October. Alas, that fix didn't turn up in this week's first Cumulative Update for the GA code. In fact, according to hardware site [2]TechPowerUp , things might have even deteriorated.
TechPowerUp noted that the L3 cache latency of a Ryzen 7 2700X CPU, normally 10ns (but 17ns in Windows 11) jumped to 31.9ns after the update was applied. There's no avoiding the fact that that is a huge jump, and one that could leave power users gnashing their teeth in distress.

The site also pointed to [4]industry talk that a further patch to fix the L3 latency woes is scheduled to land on 19 October via Windows Update.
[5]
The Register asked Microsoft to confirm this and will update if the software giant responds.
However, talk of a fix were not the only mutterings on Reddit concerning the patch and AMD kit. [6]One Redditor noted that latency already tended to swing quite wildly depending on workload: "Nothing changed pre or post patch yesterday." The poster also highlighted latency under Windows 10 hovered between 9.4 and 10.1ns while Windows 11 was anywhere from 12 to 34ns.
[7]
So we'd have to say the jury is somewhat out over whether this week's cumulative patch really made things worse or not. Our advice would remain the same. If AMD power use is your thing, it's probably best to hang fire on Windows 11 for a bit, just until things settle down.

As another Reddit poster [14]put it : "I learned my lesson a very very long time ago with windows ME (yeah I'm old), don't upgrade your Windows OS for at least 6 months after first release. A year is probably better." ®

Being a millennial apparently makes you old now.
AMD V-Cache
Since this is an issue with L3 cache in AMD CPUs, wonder if the upcoming AMD CPUs with the V-Cache will also have a similar problem initially.
mmmm im the opposite
Not sure this is all AMD chips! Since my upgrade (fresh install) my performance has gotten way better, boot time has been slahsed by 50% and the general speed and performance is much better!
Looks like that was a BIG brown envelope
So not only do we have "must run on latest Intel Silicon" ("oops, forgot Surface!", it was that rushed out.) but it also has an oh-so-accidental borkage of AMD chips, so that Intel are now top for desktop performance again!
Am I the only one detecting the aroma of fish?
Re: Looks like that was a BIG brown envelope
Some sort of [1]deal between Intel and Microsoft to screw over AMD? inconceivable !

are we getting the picture yet?
It's a HOG. It's stealing everything you have, and taking over the computer you shelled out for, but don't really own, and nobody wants back. We have a problem good people, we need a third choice, in a very bad way. We are currently Slaves to technology. Do you want the red pill, or the blue? They both end in annihilation, "choose your destroyer."
Re: are we getting the picture yet?
Linux. How hard is this to understand?
We have the third choice.
Re: are we getting the picture yet?
>We have the third choice.
VMS ?
Although I'm hearing so many stories about people being anti-VAX
Re: are we getting the picture yet?
which one? and will it run my apps? and will it give me back my computer? I have no idea lol.
Re: are we getting the picture yet?
I mean, I'm certainly not going to do an hour of research before i do trial and error to do simple tasks. I'm trying to spend LESS time with technology.
And it begins... again
Bwhahahaahahahahaahaha

Some people are such barstewards ...
