oh it's definitely RDNA 2.0. You dont hit 2.23 ghz on a rdna 1.0 GPU. The CUs also have RT hardware so it's RDNA 2.0, but the PS5 doesnt support mesh shaders or vrs, and hopefully this diagram will let us figure out just how big these CUs are compared to the xsx and PC rdna 2.0 gpus.

Cerny did talk about RDNA2 CUs specifically so I would imagine they would be in the PS5. But let's assume he did lie about that. There would definitely be a lawsuit for false marketing if that happened. Cerny didn't promise VRS, SFS or Mesh Shaders during his presentation but he did push RDNA2 CUs pretty hard with it. I don't see how Sony could win a lawsuit after that presentation.
I'm going with that they are RDNA2 CUs. However reading through some comments here there still seems to be some doubt on that.

What matters is the actual delivered result, but still, always nice to also have better specs to brag...
EDIT: it's important to remember that Sony and Cerny told is practically NOTHING about the details. All the "missing" features and specs were just wishful thinking and rumors created but "tech channels" to make a profit with the thirst of fanboys to have the best toy. All those tech channels and leakers that people in these forums love to link and quote, where are they? Don't forget to go ask for explanations about their "leaks" and "exclusive insights".

Well, if this is the case and the Forecasted Photo Unit in ps5 is half the size of SeriesX, then that explains the superior performance on photo mode in Control, and don't expect different results in the upcoming games. If you're a ps fan i would avoid the future Digital Foundry photo mode performance analysis.

Does anyone here know what features RDNA 3.0 introduces?

Why are you thinking that? Basing on this tweet?
Very rough sketch :
What is in the middle of GPU? ACEs, L caches???

He's never claimed to be an insider. He speculated it possibly could have 4mb of L3 cache. He didn't say it did. He made that clear.
He also never said there were any RDNA3 features in PS5. He said if Sony had a customisation like the GE that could make it to future AMD GPU tech. Sometimes Collaborations are beneficial to both parties. I don't know how that can be interpreted as PS5 having RDNA3 features
just "Robert Downey Gunior" do ahahah ))

The Boxes dieshot for this post clearly shows the original Zen 2 FPU missing on the PS5. Even people that don't know shit about this can compare with the annotated PS5 dieshot and notice the difference.
PS5 Die Shot has been revealed
Can someone please explain to me what is going on, by using worlds like when talking to a preschooler? None of us understand what we are seeing but we're speculating based on our bias would be a quick way to explain.
About the CUs, on that annotated PS5 dieshot I can count 40 CUS.
2 are generally for yields, leaving us with 38CUs. Remove 2 Dual CU for the Tempest Engine and we have the 36CUs for the graphics.
The rest is all there somewhere. All those custom accelerators are really tiny things.

As far as I know (please correct me if I am wrong) mesh shaders and VRS are not features within the CU, but further down the rendering pipeline. In fact every one is pointing at the GE to cull pretty much everything before rendering. Sony can do it because the PS5 is a stand alone system.
Cerny did talk about RDNA2 CUs specifically so I would imagine they would be in the PS5. But let's assume he did lie about that. There would definitely be a lawsuit for false marketing if that happened. Cerny didn't promise VRS, SFS or Mesh Shaders during his presentation but he did push RDNA2 CUs pretty hard with it.

There is no "if". I am not going to debate an improbable scenario. When there will be a court case on the issue, if ever, I'll go and debate about it, but until then Cerny's and Lu's words are to be taken as official on the matter.
It's actually 40 CUs. 4 are shut down for yield reasons.Very rough sketch :

Tempest Engine is a CU unit outside the 40 for GPU... so actually PS5 has 41 CUs if you count Tempest Engine as one... 40 for GPU (4 disabled for yields) and 1 modified for Tempest Engine.The Boxes dieshot for this post clearly shows the original Zen 2 FPU missing on the PS5. Even people that don't know shit about this can compare with the annotated PS5 dieshot and notice the difference.

Bro, The Pro came out earlier weaker and cheaper the X came out later stronger and more expensive... the Pro was beaten doesn't matter how you word it.

But these results come from the potential the hardware offers. Having a FPU of the same gen as the PS4 will hurt this potential in the long run.
The FPU yes, but the RDNA CUs are impossible to know by eye.
Comparing the dieshots, the PS5's CUs are IDENTICAL to the ones we can see in the SeX. Is the SeX using RDNA1 too?
"We" where expecting 32MB, would make sense for 36CUs and lack of space.
But this expectation was more in the field of "if we could have one dream come true". What was reasonable to expect was the unified L3 cache. Clients of AMD Semi Custom division must be able to peak into the company's near future, it was very well possible that both Sony and Microsoft could request AMD to unified the cache like in Zen 3. This is an guaranteed improvement with guaranteed benefits for gaming and would stress the transistor budget.

That guy is a beast for doing the PS5 layout so good.

Edit: He forgot to mention the Cache Scrubbers.
Also, I think you can't find the Tempest Audio Engine that easily, as it's just a CU's being utilized for Audio.
Could be any CU. Which ever one that would have been disable for yields.

Isn't there a reason why it's called "DUAL"? It may be "1 Custom/Reserved CU" for TE, but this "1" count was "2CU", physically, no?

So why haven't we seen the damage yet?
As fAr as I remember yes Series X uses RDNA1 CUs.

If the PS5 is "under specced" I am just fine with that personally. The games out for it that are exclusive, such as Demon's Souls, looks amazing, and Bluepoint has stated they aren't even close to maxing out the system.
Ratchet looks like a real time CG movie.
The games are going to look amazing, regardless.
And if the Xbox X has "much better" tech, then bring it on. I want to see them shut and deliver on that promise. That just means their first party stuff should be even more impressive, so it's time to start demanding that kind of execution and performance from the Xbox. I personally would LOVE to see that. Bring out some quality creative games that showcase what the SX can do MS!
You guys are bickering over die shots while the rest of us are actually having fun with the new games.
Of course I wouldn't be surprised whatsoever if all this armchair analysis is totally wrong. We've already heard from devs that call PS5 a "masterpiece of system design." And we saw the UE5 realtime demo on PS5. It looked revolutionary.
Everyone stop worrying and go enjoy the consoles you like. They are all completely capable of delivering great experiences.

Old engines ? Ported engines .. higher clocks compensating, tales from the ass? Who knows . What I know is , that both Nvidia and AMD are designing engines with VRS , mesh shading and SF.

absolutly not - since it was clear that Sonys price goal was 399 - wich imposes restrictions of course. Cerny would have something more powerfull developed if 499 was realistic . MS on the other hand was loosing hard in sales and at that point they could have released a 1000Dollar console - What they did , and as a note - they did it good , was to achieve a victory in the mindgames.
But now we have a new start of gen on our hands and for sure Cerny will not just emergency overclock PS5s APU to closer the Gap between PS5 and XBox X.
A gap that is not even there even if the paper suggests that there must be one. Cerny delivered the much more sophisticated silicon along side a much more balanced and foward thinking Console.

This has to be satire. I could swap ps5 for sx and it still be true on the outlier experience. Zero problems with my ps5 console or accessories. Just like most people haven't had a problem with their sx/a, there are always going to be a minority with problems. It's the same for both green and blue. Take off your tinfoil hat.

It's called sarcasm
No, it isn't, just like PS5 isn't RDNA1 based.
They are both (you might call it) "hybrids" based on an in development RDNA2 design, developed in the same timeframe with RDNA2 but customized.
btw, that video is from the same guy who have annotated the die-shots in this thread. He is purely technical and not some fanboy like some other "experts" in this forum.
Btw, now we know those "insiders" who just spread FUD (well... again).

I’m not sure about that Cerny says they copied 1 CU and customized it to works as Tempest Engine.

Honestly looking at the GPUs side by side they look the same to me. Apparently now the discussion is whether or not the FPUs will hurt the PS5 in the long run.
At the moment I'm not seeing anything that would indicate that but a lot of the negativity around the PS5 seems like things that haven't happened yet and maybe they never will.

What is it then?
Edit: the GPU layout reminds me of how their desktop cards are laid out.

Will be interesting to see how the PS5 SoC compares to the upcoming AMD Navi22 GPU (6700 XT) that also has 40 CUs.
RDNA1 and RDNA2 GPUs seem fairly similar besides the addition of RT hardware and the infinity cache.
Also, it seems like the PS5 SoC and XSX SoC are fairly similar, just arranged differently and have diff CU counts and clocks.

I find it really interesting how the GE is smack dab in the middle of all those CUs while with the SX that isn't the case.
No idea if that means anything.

Not really. PS5's set up is closer to the 6x00 (without IC of course), while XSX is closer to the old GCN setup.

I guess the question is why they did that?
So far it doesn't have a serious impact on the systems performance but who knows if it ever will.
Seems like the PS5s design defies logic but then again we haven't had a console like this.

RDNA CU’s are clustered in pairs called DCU’s as Dual Compute Units.
