Sony Principal Graphics Engineer confirms PS5 has custom architecture that is based on RDNA2. (Update: Read OP)

Rosario Leonardi, Principal Graphics Engineer at Sony Interactive Entertainment Europe, had this interesting tweet... He also confirmed there is no machine learning... You are confusing actual info with some bullshit. There is a full GCN support for hw BC. That's why it's "RDNA1".

The same engineer who "confirmed sub-RDNA2" further ellaborated and actually clarified that it is heavily customized and actually based on RDNA2, minus a feature (probably VRS didn't make the cut after all).

PS5, l'architettura non è RDNA 2? L'ingegnere Sony chiarisce le sue dichiarazioni

L'architettura di PS5 non è RDNA 2 pura? Sono state trafugate alcune dichiarazioni di un ingegnere di Sony, che ha poi fornito ulteriori chiarimenti sulla questione.

Inevitably ended in the midst of a fierce controversy, the engineer clarified his statements to make people understand exactly how things are. His new messages, which are also private and unfortunately shared on social media, are very interesting:

"RDNA 2 is a commercial theme to simplify the market, otherwise GPUs with completely random features would come out and it would be difficult for the average user to choose," wrote Leonardi.

"For example, support for ray tracing is not present in any AMD GPU currently on the market. (...) The PlayStation 5 GPU is unique, it cannot be classified as RDNA 1, 2, 3 or 4."

"It is based on RDNA 2, but it has more features and, it seems to me, one less. That message turned out badly, I was tired and I shouldn't have written the things I wrote", continued the engineer, complaining that he received insults for his statements.

[Sir Vilhelm]

Going to monitor this thread and see how gaf explains how this is a good thing

 

[jaytyla]

Oh shit.....

 

[Craig of War]

So no machine learning and between RDNA 1 and RDNA 2 so even the architecture is of variable frequency lol

 

[rob305]

 

[VCL]

wow that sucks

 

[jigglet]

Now watch people discredit him as just some lowly employee. There will be plenty of creative ways to downplay his job title.

What's the Xbox Series X?

 

[jigglet]

What's the Xbox Series X?

RDNA2

 

[godhandiscen]

For decades of experience console warring, I doubt we'll notice the difference. Microsoft would have made a bigger deal out of this if they could, or perhaps I missed the memo.

 

[Sir Vilhelm]

RDNA2

Doesn't it also have machine learning?

 

[Jack Peterson]

That's gonna be a yikes from me

 

[Thugnificient]

Principal graphics engineer. What the fuck does that guy even know? I have Cerny on speed-dial, thank you.

 

[Potato Chip PRO]

Someone from YouTube said that the PS5 had RDNA 3 features............. He was full of shit apparently.

 

[JLMC469]

Now watch people discredit him as just some lowly employee. There will be plenty of creative ways to downplay his job title.

They are already doing it.

 

[jigglet]

They are already doing it.

I’ll get the ball rolling: “He’s a graphics engineer not a processor one!”

RDNA2

So we could end up with a situation where we have one console with 10.2 RNDA1.5 tflop (variable) vs one console with 12.2 RDNA2.0 tflop (sustained)?

Perhaps the gap is bigger than the 17% people talk about.

OR its the same for Xbox Series X - it also use RDNA1.5?

 

[ANIMAL1975]

Mind-blowing, it's a custom chip they could choose whatever they want from what AMD had to offer. For instance geometry engine is in RDNA1 _ hardware support to geometry in the gpu _ Sony took it and customized it, see road to ps5 again about geometry engine and primitive shaders, it's all there...

 

[Andodalf]

Doesn't it also have machine learning?

RDNA 2 has some built in LM capabilities, and SX has support for 4 and 8 bit precision on top of that

 

[Mobilemofo]

I heard he was chief engineer on massage my balls, the ps2 classic.

 

[SplunkyMunkey]

Im having a hard time on who to believe this guy saying inbetween RDNA1 AND RDNA 2 then cerny at hes road show based on RDNA 2 and even lisa su from amd also said both consoles are RDNA 2 and theres rumoured rdna features not found on series x so who do u believe?

Not how it works. No such thing as RDNA2 or RDNA1 FLOPs.

 

[Gamerguy84]

Hey OP console wars make you look stupid.

 

[OverHeat]

Can’t be true...Sony drop the ball if it’s correct

 

[Thugnificient]

There are NAVI-based versions with dedicated dot product processing.

AMD sells those cards specifically for ML work loads.

The guy is ignorant.

Took longer than expected.

 

[BluRayHiDef]

Who cares? All that will matter is the quality of the image that the PS5 will convey to TV screens, and based on Sony's track record, I'm sure that it will be great. No one will care about how the quality will be achieved.

 

[lastmessiah]

I've known the PS5 isn't RDNA2 ever since the first reveal. But some people just can't handle this information.

The only thing i can think of is rdna 1 features and rdna 2 core since the core on RDNA 1 wont able to overclock to an inpressive 2.23

Mark Cerny actually said that the PS5 GPU is "a custom AMD GPU based on their RDNA 2 technology." Cerny never said that it was RDNA 2, but rather based on that architecture. Cerny customized the PS5 GPU to his vision to make the PS5 run more efficiently, better, and faster by getting rid of all the various bottlenecks and a blazingly fast SSD. I trust Cerny's vision, and for him to deliver an awesome product. The PS5 is highly customized, and doesn't use the traditional PC parts, and it's better for it.

 

[DESTROYA]

Yeah I believe what Cerny and Lisa Su says before a guy I’ve never heard of before.

 

[OverHeat]

Someone post this on the other site for major meltdown!

 

[Dr.brain64]

No ML?





heck yes

 

[JLMC469]

before a guy I’ve never heard of before.

Use Linkedin...

But he didnt actually mentioned RDNA 1 otherwise he would of mentioned custom RDNA 1 to me and to everyone its based in RDNA 2 modified

 

[DESTROYA]

No thanks, why just not list his resume or whatever

 

[Thugnificient]

If this is indeed accurate, it seems to br RDNA2 with cut features, effectively making it not full RDNA2, hence "between RDNA and RDNA 2".

 

[JLMC469]

faking dm is astonishingly simple (there are websites dedicated) and it's amazing how some people eat everything they read on the web without questioning.

More like RDNA PS5.

 

[BluRayHiDef]

By the way, this information doesn't contradict what has been revealed previously about the PS5's GPU; we've known for quite some time now that it doesn't have all of the features of RDNA2 but only the features that Sony determined to be truly beneficial to a console (rather than a PC) and that these features have been combined with proprietary technology exclusive to PS5.

 

[Barakov]

I can't wait for these consoles to come out so the usual suspects can knock it off with this fucking shit.

 

[Thugnificient]

Does the XSX have ML?

Twitter is a shithole that a never I click on or is my go to place for info , such a vile disgusting toxic site.
