It looks like AMD found the missing gaming performance.

I seen this video and it looks like it had to do with branch prediction and also they got double digit peromance gains for gaming and this update also helps with all Zen CPU's,they didn't say anything about workload stuff in their retesting which I was hoping they would because I know a few reviewers said they didn't see the performance gains that AMD claimed they would in Handbrake.

I hope this also help's with workload stuff as well.

 
I'm not sure if he did or not,I know that he said the update gave all Zen CPU's an uplift.

The only thing that really sucks about that video is that there is not word mentioned of workload performance uplift's and if there are any at all,I can see that they were to busy to do them and hopefully they retest or Steve at Gamers Nexus restest's that as well.

I know that Steve at GN when he first reviewed the 9900X he said that was surprised to see that the numbers he got running Handbrake weren't even close to what AMD said they would be.
 
To my understanding performance gains are expected for all of Zen 5, Zen 4 and Zen 3, as well as Intel, in Windows 24H2. I look forward to it! (preferably not from anyone called Steve).

I didn't get to watch the video al the way to the end. Didn't he test Intel CPUs also with 24H2? If so how did they do?

He tested only a few games so far with Intel. Gears 5 showed a large improvement (not as much as Zen 5) but others did not. AMD said the reason for the improvement is because MS was still applying Spectre/Meltdown software mitigations to Zen 3 - Zen 5, even though they have hardware mitigations in place. So the software mitigations were unnecessarily reducing performance. This has been fixed in the new Windows 11 build. Intel CPUs don't seem to have the same issue (software mitigations are not being applied to Intel CPUs with hardware mitigations in place). Gears 5 is the outlier so far as Intel gets a large boost there as well, so probably more than just the software mitigations issue going on.

I put together a chart showing the RPL game tests that HWUB has so far (note that the x-axis starts at 140). They said that more testing is underway.

Edit: To add, there are 4 interesting questions remaining. First, can any other reviewers verify these results? Second, over a larger selection of games, does Intel show more uplift or is Gears 5 an anomaly? Third, do the X3D chips also see significant uplift? Fourth, do other apps show significant improvement as well?

We'll get answers to all 4 questions in time but if everything breaks AMD's way with this, Intel's going to have a steep mountain to climb trying to catch back up to AMD. Alternatively, this could be a screw-up in HWUB's testing and there's not much to actually be gained. I'm guessing that the truth will fall somewhere in the middle, as it usually does.

I did the upgrade via ISO last night.. guess ill see if i can notice anything on my 7600X tonight (im not holding my breath) , Just hope it doesn't have any negative issues like Stability etc.

AMD confirms Branch Prediction Optimizations are now available for Windows 11 23H2, boosting gaming performance - VideoCardz.com

Branch Prediction Optimizations were backported to Windows 11 23H2, 24H2 update not necessary AMD confirms that the optimizations are also available for older version of the operating system. As reviews have shown, the upcoming Windows 11 24H2 update, which features Branch Prediction...

Optional update is available through Windows Update if you want the changes in Win11 23H2.

I'm going to skip it for now as new game content just dropped and I'd like to get some before/after test results, which will take away from my gaming time in short term.

And from what I was reading on the reddit thread discussing that patch some people's performance went up and some went down. Would wait for verification.
 
@Janus67 I'm wondering if the people tat said their performance went down if they did clean install's of Windows,I think it was hardware unboxed but I'm not 100% certain but in a video I seen by a credible reviewer said that he noticed that after running test's one time with the same CPU and video card in the same system hold get different result's.

I'm pretty certain he also said that even doing many install's of Windows he didn't get consistent result's sometimes the performance would be more or less.

I think if it were me I would download the insider ISO and do a clean install of Windows incase when the branch prediction doesn't apply right or well with an update.

I'm going to wait before singing any praise's either but this is look good.
 
I've got deja vu....feel like we knew all of this?

Oh good... this may save some time rebuilding the review OS and retesting....

That's a fair point, although I think that for 99.9% of people they would be going in expecting to see a reported boost in fps whether or not they did a fresh install.

I can fully imagine a fresh not yet bloated other than required apps install of Windows will perform better than ones with who knows how many updates, drivers, etc all over the place.

So far, 3 reviewers have published test results on this and all 3 found significant increases. Some games don't improve at all while others have large improvements (30%) and everything inbetween. Looks like on average, it's a 10 - 15% increase in gaming performance.


HWUB avg performance uplift = 11% with a 9700X
Hardwareluxx avg performance uplift = 12.8% with a 9700X and 13.8% with a 9600X
Donanim avg performance uplift = 10.4% with a 9600X

Hardwareluxx also had results that showed Zen 3 and Zen 4 also benefit, including the X3D chips. Zen 3 benefits the most (~17%) and Zen 4 the least (~5%). HWUB had Zen 4 benefiting only slightly less than Zen 5.

What the guy at hardware unboxed was saying and I didn't make it really clear in my first post is that he did testing with a fresh install of Windows and then went back again a few weeks later and retested with the same rig and set up and a fresh install of Windows again and got different result's every time.

You see what he's talking about in this video at the 9:24 point.
