I would say at best they were illegally attained. "If it looks to good to be true...".

The results seem to suggest that 24H2 has a newer kernel or something coz the backported patch goodness isn't as good as the 24H2 goodness.Computerbase has some preliminary benchmarking data with the new updates:

Look at the results for F1 24 and Outcast. There could be other games like these.What are you seeing that I'm not?

Dang it. Now Microsoft is keeping good stuff away from regular users while those with the latest Ryzen AI laptops get it first. I don't want to subscribe to some dang insider channel to get the good stuff.
Nice, detailed setup. I wish they mentioned the BIOS settings by name too. I also hope for 9950x/9900x they will provide information if core parking was used or not. One could wish that such detailed setups would be a norm going forward, I mean every review containing detailed BIOS + Windows settings listing in addition to drivers used + version of monitoring tools used + versions of game / software that was tested. That at time would allow to avoid some internet drama over differing results...Computerbase has some preliminary benchmarking data with the new updates:

So how does Windows 10 fit into all this? I cannot access the core isolation function in my system, says unavailable. Is Win10 by default at the top of this list, or the bottom?
Run win10 in super admin mode, I guess !?So how does Windows 10 fit into all this? I cannot access the core isolation function in my system, says unavailable. Is Win10 by default at the top of this list, or the bottom?
presumably slower than win11 with the patch.So how does Windows 10 fit into all this? I cannot access the core isolation function in my system, says unavailable. Is Win10 by default at the top of this list, or the bottom?
Thats not at all a given. See video from August 15 below.presumably slower than win11 with the patch.
Definately a scam. Better to report now.This guy from Canada keeps selling 9900Xs for under $400 US. I was tempted, but looks sus as hell. What do yall think?

The difference to previous gen is still small after all all those updates, 5-6%. That's equivalent to like, 230 MHz clock increase on some 5.5 GHz part. Worth something like 30-40 extra dollars, but not much more. Currenly 9700X is 80 dollars more expensive than 7700X.The AMD Zen 5 Gaming postmortem: Larger generational gains than many reported, game-boosting Windows Update tested, Ryzen 5 7600X3D gaming benchmarks, too
Objects in mirror are larger than they appear.www.tomshardware.com
Yes, as Tom's says, the performance is better than what we initially thought, after all that was done to "fix" it, but the performance is still lower than what AMD promised, isn't it?
IMO the disappointment remains.
Pretty good test from Toms this time 👍Another mega test of the 24H2 update impact:
Additionally, many say that the Windows update boosts AMD’s performance not only because of branch prediction optimizations but also because of a correction that reduces the overhead of Meltdown mitigations for a security vulnerability. We asked AMD, and the company refused to comment, which should tell you all you need to know — they could have simply denied it but didn’t. Technically, an ‘improvement to the branch prediction unit’ would completely align with reduced overhead from a mitigation because Meltdown attacks speculative execution functions. That means that larger gains could be seen when testing with the performance-sapping virtualization-based security (VBS) feature turned on.
However, because Microsoft has posted instructions on how to disable the feature if you prize gaming performance more than security, we always conduct all testing with VBS off to extract the full performance potential of the chips. So, you could see a few more percentage points of performance gains based on your configuration.
We wrap up here with only the results using the new version of Windows. Note that due to time constraints, the Intel chips are tested here at true stock memory settings, whereas the AMD chips have Expo memory overclocking enabled, so Intel will perform better with tuned memory. I’ll add the overclocked memory results for Intel in an update to this article. We also have the as-yet-unreviewed Ryzen 5 7600X3D, a Microcenter exclusive, in the test pool, but this chip is only tested with Expo memory settings.
The Ryzen 5 7600X3D with Expo overclocked memory settings delivers about the performance we expect, beating out the $530 Intel Core i9-14900K flagship with stock memory by a small amount. That’s impressive for a $300 chip, but it does come with drawbacks in application performance. We’ll post a review in the coming days to suss out the true differences, but this is a great first showing for the chip.
The Ryzen 7 7800X3D continues to dominate our gaming benchmarks easily, while the Ryzen 7 7700X with Expo enabled beats the 14600K but still lags behind the bare stock 14900K config (remember, this is a proxy for the 14700K as well, which would be about 2% slower than the 14900K). The Ryzen 5 9600X has pulled into parity with the 14600K, but the latter would take the lead with tuned memory.
Even after the Windows update and with Expo memory overclocking removing Zen 5’s memory speed advantage, we still see decent generational gains for Zen 5 over Zen 4. Measuring across our entire test suite, the Zen 5 Ryen 5 9600X is 9% faster than the prior-gen Ryzen 5 7600X, while the Ryzen 7 9700X is 7% faster than the prior-gen Ryzen 7 7700X.
The big takeaway here is that, regardless of memory speeds, the type of benchmarks used, or whether the Windows patch has been applied, the generational gains for Zen 5 gaming are larger than we’ve seen in many reports. Whether or not that justifies purchasing one of these chips over the Intel comparables is a different matter, but we’ll update our reviews with updated buying advice over the coming days.
Hardware Unboxed is also testing with disabled VBSPretty good test from Toms this time 👍
Performance increase from the windows update (do note lower than other outlets since they tested with VBS disabed from the get-go)
That at least shows consistent messaging as both rumors and official communication suggested Intel should see nothing as the issue was, if we believe rumors, with Zen/Zen2 mitigations being applied to all Zen cpus.Sadly there is no benefit for Intel with the new windows update

This patch is really cryptic. Z5 is 4 wide or 8 wide decode?
It currently is 4 wide x2, so there are some chips that are really 8 wide? Is there some issue with the current stepping that they deactivate the chicken bits?
