Info 64MB V-Cache on 5XXX Zen3 Average +15% in Games

[Kedas]

Well we know now how they will bridge the long wait to Zen4 on AM5 Q4 2022.
Production start for V-cache is end this year so too early for Zen4 so this is certainly coming to AM4.
+15% Lisa said is "like an entire architectural generation"

The fact that a 5900x is outperformed by a 2700x in average frame rates and a 3600x outright tells me there are some major issues to work out on the AMD CPU side.

A single threaded tech demo in 2022? That seems unlikely to be the future of anything.

I think I read that Zen 3 actually only gets the minimum latency out of the L3 with a set size of 8 MB or less since it overflows the TLB at that size. If they enhance the TLB (very likely), then average L3 latency could go down significantly, even with no L3 size increase.

Great point. This is what the TLB penalty looks like in AT's Zen 3 deep dive (by Andrei Frumusanu):

There's actually no Matrix demo for PC (yet?). The only thing that exists is project data of the city than can be compiled (which obviously wouldn't be optimized beyond anything UE5 offers at stock).

Those numbers do look weird but it also also be Single CCD vs dual CCD at least with the Zen 3 parts.

There are sometimes when the 5600X and 5800X will out perform the 5900X and 5950X due to the latency in single vs Dual CCD aslong as your workload is not bottlenecked by core count.

The CCX/CCD penalty in a 2700x is way worse than on a 5900X. There really shouldn't be any workload where a 2700x outperforms a 5900x and this holds especially true for gaming. There is a major issue going on on the AMD CPU side. It looks like have multiple CCDs is making it worse, but there is a bigger underlying issue here.

How do you trust a picture of a Russian (??) benchmark ? Its not a link to somewhere on the web, so it may not be real ?? I am not accusing, just saying what if .

The CitySample part is the same thing as what you get on the consoles. You just don't get the chase scene.

They obviously didn't optimize it that much. It's just meant to be an example for developers.

That is why I specifically said in the Zen 3 line and didn't reference the 2700X. And this is still an optimized PC tech demo so I wouldn't take those results as gospel.

I think you mean un-optimized, which I agree with. I would say it's more than just not optimized though and needs a bug fix pass for AMD CPUs. Either way, I think we agree that this shouldn't be used as a measuring stick for CPU performance which is what the poster I originally responded to was doing.

Nor anything involving any Matrix characters.

What else can we do? Not like you are gonna use your 3080 Ti with your farm of CPUs to bench this tech demo

So due to Covid the Anand Tech Review of 5800X3D was postponed.

"Unfortunately we're not going to have a Ryzen 7 5800X3D review out for today. Despite herculean efforts from @gavbon86 to get the necessary testing done in time, COVID has won this round. We'll have something next week."

Looks like an issue with the dual chiplet CPUs. The 5600X does better than all of them.

I'm pleasantly surprised there even is a forthcoming review... Anandtech isn't what it used to be these days.

Milan-X Delidded

https://www.tomshardware.com/news/epyc-amd-milan-x-delidding-reveals-a-surprising-lack-of-separate-silicon-shims

So they Cut and killed a $10,000 CPU just for Science.





We need volunteer so we can get an IR shot of Milan-X/5800X3D from
OC_Burner AKA Fritzchenz Fritz Pronto..





Don't you love when High$ and Super Expensive CPUs are destroyed just for Science? I mean, Yes thank you, because I can't afford it any ways.

 

[nicalandia]

My Guess from the Milan-X Delid is that they were expecting three separate structures on top of the CCD die, but only found and single structure or what it looks like one since it's not a IR or other wave length camera.

According to the source they believe AMD is placing another silicon support on top of the 3D V-Cache/Support structures. This to me seem rather unlikely due to the Hight issues, the CCD does not seem to be any thicker than a regular CCD(AMD has said that both the L3 die and structures are thinned down) so what I think it's happening here is that after both the L3$ die and Support are placed on top of the CCDs they are sand down making it appear to be a single support instead of being three structures.







Edit.

Never Mind. It is a Single Support Silicon on top of a Thinned Down CCD

Plenty of good reviews already.

Plenty of good reviews already.

I can't wait for AnandTech SPEC06/2017 numbers that are not done at ISO speed.

The ONLY time AnandTech Review team did a test with SPEC at ISO Speed(as to compare IPC) was when they were testing Skylake 14nm with Skylake on 10nm... The rest of the time they run SPEC at stock speeds

 

[Schmide]

I wandered out and picked up an x3d. There were 6 left at MC and some aussy said they were selling out down there so I went.

Ironically my clucker is going from a 5800x.

It all gets traded down...

What was the increase in L3 cycles over the regular 5800X? 3 some cycles?

AMD’s Ryzen 5800X3D is too flawed for consumer use

Today AMD releases their long awaited consumer 3D V-Cache CPU called the Ryzen 5800X3D and it is not as good as expected.

semiaccurate.com

On the latency front the L3 cache on the -3D is about 4 cycles slower than the non-3D parts, something AMD went to very tortured lengths to try and minimize in the briefings.

He seems annoyed that AMD released this as a product.

hmm he seems to write very much like the person behind userbenchmark

"The 3D V-Cache is a really good idea for number of server markets but the flaws mean it has no real market on the consumer side. Sure it can put up a few good numbers but the 5800X3D is so ill-suited for the task at had it makes us question why AMD bothered. Oh yeah marketing. "-SA article above

"AMD’s marketers continue to show more interest in this year’s bonuses than the longevity of the brand. Instead of focussing on real-world performance, they attempt to dupe consumers with benchmark busting headlines. " -UB 5800x3d bio

Maybe its more of a niche chip than I realize but I don't see where this sentiment comes from.

Jayz2cents is similarly pi**ed. I won't even give him the benefit of linking to his whingy video about AM5, which is full of baseless speculation at best, and flat out lies for the rest. The video came out within a day of the X3D reviews, none of which are on Jayz channel.

 

[Dave3000]

Does anyone know how a Ryzen 5800X3D performs in X-Plane 11 compared to a 5800X or a 5600X, especially in Vulkan mode?
