HUB testing showed quite nice gaming performance gains for both Ryzen 4 and 5. Wonder if it's gonna do anything for my 5900. Will benchmark a couple of games.

Already tested my 5900X, didn’t see any performance gains in settings that I normally use in my games. Nothingburger for Zen 3 it seems.

I'm getting the same uplift on a 5800X3D that people are reporting on Zen 4 and 5. So either you don't have the update, or just your settings/what you tested didn't benefit. But that's on 24H2, I already updated to that before these changes were supposedly added to 23H2.

Updated to KB5041587.

Dunno what to tell you. Updated as soon as it went live, tested my usual gameplay in Cyberpunk, RDR2, Forbidden West and the Wukong benchmark, so all the games where significant gains were reported and got exactly zero uplift. Perhaps if I ran at low settings there would have been something there, but that's of no use for me in a real-world scenario 🙂
I guess we'll see when others report in.

I need to test the update. But need to disable admin mode first. As that gave me tangible boost. I wonder if 24H2 has some extra apart from the branch prediction.
Tho the games you mentioned I doubt I would get any boost even if there was some with my 6800 XT.
mackintosh
Maybe 24H2 does something different indeed. I simply installed the update that was released by MS yesterday. Didn't make any other changes to my system. It's also entirely possible that it's something on my end. This is my main rig, it's full of stuff running in the background all the time. This is why I keep hoping the usual suspects will eventually do a proper, comprehensive retest across the board.

for me a massive uplift in performance, got from 6600 in 3dmark cpu test to 6900, with stock settings, before i had to rise mem speeds and do curve optm. for the same results, ca. 6900, now it runs without any tweaks the same points. nice ! will test with tweaks later on.

To those seeing no performance change, you might be graphics card limited

I discovered today that if a game features the NVidia low latency button and that it is enabled that all the setting may not transfer over enabled when switching to the administrator account even though they show that they are enabled.
Got that. 😛
So when testing games on the administrator account disable the low latency button in game.
Just to be safe reset the game setting you want and re-run the game.
Other than that my games run the same form user to admin account no real difference for me worth talking about. 🙂

Updated to KB5041587 on Windows 11. Didn’t see any performance gains on games that I tested (Cyberpunk 2077, Wukong, Shadow of the Tomb Rider, TimeSpy Extreme, AC Mirage, Warhammer III). Ryzen 7 7800 X3D, 4090 FE, 32 GB ram 6000 mhz.

In Remnant 2, I went from around 90 fps, to around 100 fps, in the home hub.
I'm using 24H2.

KB5041587 Probably not working as intended. No perf gains.

Don't we need a new Chipset driver too? AMD said so.
Undying
Tried some Spiderman MM game is really cpu heavy but didnt notice that much difference but i didnt do a full benchmark just some testing of swinging around the city.

Uplift will vary from game to game. Some games will se NO uplift at all. Other games will see from 2 to 10% and some will see way above 10% up to 30% uplift.
An old benchmark like Valley gets ~10% uplift on my 5900X (soon 9950X).
EDIT
Just be happy this came out as fast as it did. I'm sure ZEN5 will se further improvements (albeit small) with newer chipset drivers and AGESA updates.

Perhaps your security settings are different -- maybe if you already have virtualization/core isolation (etc) off the uplift is not present. I'm just speculating for why you might see a difference. I always had that stuff off personally as I get paranoid about these exact sorts of problems 😉 I acknowledge I am at greater risk as a result, but I've not had a problem yet and I basically only use programs I trust.

Mine wasn't an option, it was in the normal update section.
BlindBison
I'm not faulting your choice by any means, I don't want to miscommunicate -- the uplift from 12/24 to 16/32 and the new generation is meaningful, but I am curious to your rationale for upgrading to the 9950X right now.
The 5900X is quite a capable CPU I think and, for me, if I'm upgrading an entire platform (AM4 -> AM5, new RAM, etc) I would want to do so following a tremendous architectural leap. For my workloads at least Zen 5 doesn't seem to be that -- it's an upgrade of basically 1 "good" generation where the bulk of the performance came from Zen 4 + new RAM speeds/platform more or less.
If you're willing to wait a bit it's possible Arrow Lake from Intel would be better ("maybe" lol) or if you were willing to hold onto that 5900X for a bit more life Zen 6 or the X3D variants might also work out nicely. But time is money and all that -- if you use workloads where the extra cores can come into play and don't want to wait or use specific workloads like AVX512 then I do understand. It's a beast of a processor even with me being a little disappointed by it 🙂 Congrats on your upgrade!
BlindBison
I think I'm misunderstanding what you mean perhaps -- do you mean the reflex option/control panel ULLM mode aren't saved if you swap to Admin account?
I would definitely expect somewhat different CPU bound results since CPU prerendering should in theory help the CPU out a bit with keeping the GPU fed as I understand it. One would certainly want to test like-for-like before and after new patch.
