Isnt 10 - 15 % an expected margin for a new cpu release?
our workstation or synthetic benchmarks such as Cinebench, Blender, V-Ray, Corona, Handbrake or even 7-Zip and Geekbench do not benefit from the optimizations.
Testing like this bothers me. 720p testing is only relevant at 720p (which 0.23% use). It's results are supposed to isolate the cpu in this case, and it does, but it doesn't scale with higher resolutions. So.... what good is that value for everyone else if that's all they report? For example, it's reported there is a 10% increase at 720p, but at 1080p it's 3% (and potentially even less higher). I just don't see the value of the isolation of that number without sharing the rest of the resolutions.the rest were at 720p

From https://www.mersenneforum.org/node/22559#post1052498Spoke to several of the senior chip designers at Hot Chips. They're quite pissed at Microsoft for screwing this up.
They also told me more about some of the various regressions and other peculiarities that I wrote about in my blog. Some of their more junior chip architects also showed up which I managed to catch.
I can't go into detail since some of these discussions were understood to be under my NDA. But in short:
- They know what's going on with games, but wouldn't comment further or tell me what the issue was.
- The core-to-core latency test is hitting a "weird situation". Based on what I learned, I told the Chips and Cheese guy who wrote the benchmark to rewrite it a different way to see if it changes anything without actually saying what the issue is. I can't comment further though.
- The 2-cycle SIMD latency regression was a calculated decision. My AMD contact implied months ago that I caught the chip architects surprise by "finding" the 2 cycle latency. I now have the full context on this story after hearing it from their side. It will not be fixed in future Zen5 chips since it's a design issue. (we all knew that already) I can't comment on whether it will be fixed/changed in Zen6 - though I have a feeling that the discussion may influence their decision on what the future (Zen6) will be.
- My "guesses" at the structure of the 512-bit store behavior is only half correct. I spoke to the guy who did the RTL for Zen5's store unit and he basically explained to me exactly how it all worked. (It was funny because he wouldn't say anything unless one of the lead Zen5 architects were there to authorize it.) Of course I can't say anything publicly. Though my confidence of Zen6 having 2 x 512-bit store has decreased from when I wrote the blog.
- They told me why only Granite Ridge has the 2c FADD while Strix Point does not. Can't comment further though.
- They said their FPU guys loved my section on the VP2INTERSECT and got a good laugh out of it. But no comment on whether they will keep that instruction going forward.
- One of the lead architects "thinks" he knows why it's so hard to get more then 4-wide decode on a single thread. But made no further comment.
- The load store guy said "he'll look into" why some of my load/store tests didn't reach full throughput.

Above post from writer of Y-cruncher, who has done the best technical look at Zen 5 that I'm aware of so far.
I do wonder what behind the scenes stuff is going on between AMD and MS. Was MS expected to have put the update into general release before Zen 5's original launch date?

The ASUS ROG SRIX is supposed to be out Sept 30th and there's no word on when the rest come out which is really stupid if you ask me,they should released 1/3 to 1/2 on the same day and some gaming and some Workload mobo's.When can we expect x870e available on Amazon n Newegg?
I understand the purpose.So there's a practical viewpoint (nobody games at that low of resolution) and the more academic viewpoint (want to entirely sure the GPU is out of the equation to compare CPUs, even if it's unrealistic).
It's marketing/for clicks... flavor of the week. The week before....psssssssssh!It feels weird to see the market pushing 4K and at the same time trying to prove that something is so much better showing 720p/1080p results.
I can not over state how much work went into tweaking around apps n performance to get native 4k/24hz video playback on a Windows OS .It feels weird to see the market pushing 4K and at the same time trying to prove that something is so much better showing 720p/1080p results.
The Strix has les PCIe slots then the ProArt and I need at least 2 for sure to run the stuff I want to run.Most models are expected no earlier than mid-September. I assume the distribution already has many of them, but because of internal agreements, they can't sell them yet. Some stores may sell them earlier.
I don't expect anything exceptional from these motherboards. The main difference is USB4, which higher 600 series motherboards already have.
I guess we will see more new things from the new Intel series. I was counting on various changes in the new AMD, but we have to wait some more for something really new.
@wade7575
Why do you want the ProArt series? It looks pretty good, but I assume it's more like TUF with different covers, so it's a nice looking mid shelf that won't have as good support (BIOS etc.) as Strix or higher series. I can be wrong, but this is how ASUS has worked for years. On the other hand, there are so few changes that I doubt these motherboards will need many BIOS updates, and I don't think we will see any higher RAM too as all mobos are specified to be about the same as X/B 600 series. If I'm right, AMD also won't support CUDIMM (at least not at the start).
