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.

 

[MasterCornholio]

This. RDNA 2 cu's should be legit unless Cerny told a massive lie. He was specific about this.

The tweet is intriguing tho.

What's FPU?

No idea but maybe the PS5 doesn't need it?

I know they tend to cut out things they don't need in consoles. Maybe they did that here?

 

[MonarchJT]

well I'll trust Locuza whatever he find out on twitter. He never wrong

Some one posted a picture of PS5's SOC and a lot of people who think they are engineers are discussing that picture. Xbox fanboys are hoping it proves xboxs superiority, ps5 fanboys are hoping for secret Cerny sauce.

 

[Epic Sax CEO]

Link this tweet too:

My interpretation of the floor plan PS5 floor plan:
1. Bomba surprise that Sony likely cut down the 256-Bit FP pipes to just 128-Bit.
2. No Infinity Cache/L3$, also not on the Xbox Series.
3. Might have the old Render Backend design, need higher res to say for sure.
4. The WGPs are arranged as on RDNA1 GPUs with two sub-arrays.
Same goes for the Xbox Series.
Navi21/22/23, Van Gogh and Rembrandt only have one sub-array for all WGPs.
5. Higher res needed for a closer FPU look, GPU frontend analysis and details like the Tempest Audio engine.

 

[MonarchJT]

BTW where is coming that nonsense of Infinte Cache? It was a no go since we saw the size of the die... there is no way to have Infinite Cache.

Infinite Cache is a big part of Navi21 silicon.

the nonsense come from those RDG fanboys. go ask them

 

[chilichote]

FPU = floating point unit

 

[John Wick]

Told people last year to hold on with all the infinity/shared cache stuff until it was confirmed, but people love that secret sauce taste.

You didn't tell people anything beside clicking on the triggered emoji like a little kid.
No one claimed the PS5 had infinity cache. Everyone was surprised how the PS5 was performing better on CPU intensive games with a lower 100mhz clockspeed. So people speculated, some said the IO and efficiency were better and made the difference and others guessed maybe the PS5 had Infinity Cache. It was pure speculation by most and no one hard confirmed it. Maybe read or listen to everything they state before jumping the gun.

 

[MasterCornholio]

Sure , that’s true . But wouldn’t it be great if it was forward looking ? And supporting engine designs of the future? Or is it better that the market leader can dictate the market and how engines are build and designed ?

I don't understand what you're trying to say.



I wouldn't exactly say that the PS5 isn't forward thinking. It certainly doesn't seem like it's built like a last gen system.

 

[ethomaz]

the nonsense come from those RDG fanboys. go ask them

Who is RDG?

 

[Garani]

When did I mention Cerny? You made that up.
I'm talking about the people here and on Twitter who were saying this unified L3 cache was "basically confirmed" and running with it as fact.

It was a multiple reply, and I was just pointing out that if Cerny never mentioned it, then it was hot air. Cerny did mention that the CUs are RDNA2, so the CUs are RDNA2.

What's FPU?

Floating Point Unit, the math processor. Being 128 it makes it less precise than the 256 version on the Zen2. But it may be that the math processing for graphic may be done some place else, and alas the CPU may not need such precision.

Also people forget they went with liquid metal so they didn't have to use more expensive heatsink.

I think we can all write off PS5 overheating issues.

Someone actually replaced the liquid metal with normal thermal paste and the PS5 worked as expected but at a higher temperature and faster fan sped. But had no overheating issues per se during the test.

 

[Outrunner]

No, cause we don't want to pay 800 bucks for a console.

 

[John Wick]

He never confirmed it had Infinity Cache. He even stated it was pure speculation and to take it with some salt. And it's RTG

 

[MonarchJT]

Who is RDG?

Red Gamign Tech...some fanboy who here on the forum until a few days ago had to be taken into consideration more than Digital Foundry

 

[TheTechnician]

Who is RDG?

you dont know (R)ed (D)ead (G)aming?

to be honest that sounds like a nice Youtube channel name

 

[MonarchJT]

lol )) I would sub for sure !

 

[oldergamer]

So infinite cache was a lie huh! RedGamingTech and Mlid kept feeding us lies all this time just for views

not gonna say i was surprised that was BS

 

[ethomaz]

Link this tweet too:

I agree with all his info here... the FP units is not the same as Zen 2 it is smaller.
There is a big pet of the silicon that we don’t know what is and it is too big for I/O only... Tempest Engine should be of the size of a CU so there is a lot of unknown space yet.

 

[FranXico]

So people speculated, some said the IO and efficiency were better and made the difference and others guessed maybe the PS5 had Infinity Cache.

No, people were speculating about a different cache arrangement for the CPU cores. Infinity Cache was ruled out a long time ago, since the chip was not large enough for that.

 

[ethomaz]

He never said PS5 has Infinite Cache.
He speculated that the cache scrubbers (confirmed by Cerny) is probably something like Infinite Cache.

 

[chilichote]

The FPU does not necessarily have to be installed in the CPU. It can also be in the I / O complex. Or, for reasons I don't understand anyway, Sony thinks it can do without it.

 

[ethomaz]

This.

RGT more speculated about L3 cache of the CPU that is not even related with the Infinite Cache of the GPU.

Seems like Xbox fans uses Apples to talk about Bananas.

 

[ethomaz]

The FPU does not necessarily have to be installed in the CPU. It can also be in the I / O complex. Or, for reasons I don't understand anyway, Sony thinks it can do without it.

The I/O complex is probably on the opposite side of the CPU... two extremes... so I don’t believe the FPU is there because it could generate a big latency.

I was reading it alright and laughing, it was obvious to anyone with a brain that infinity cache used too much die space, so when they realised that was impossible they moved onto the shared L3 rubbish, now that looks like it's been debunked just as I said

 

[MonarchJT]

yes yes he also heard about ps5 rdna3 features. follow him is a total trustworthy source

Unrelated... you need just to stop to spread FUD the others didn’t said... you made up too many things in the last 24 hours.

 

[Kholinar]

Yes, let's rake RedGamingTech over the coals even though he NEVER said the PS5 had infinity cache for certain. People love their scapegoats, eh?

 

[azertydu91]

It feels a bit schizophrenic to have Johnny Silverhand answering to John Wick, maybe someone with a Neo avatar can join in?
I have lost hope of ted coming to the discussion.

 

[Loxus]

Has anyone notice this about the GPU.
The middle of the GPU has something in it which I highlighted as purple is being mirrored by 1 and 2.
Looks like the 40 CU's are mirroring each other with something in the middle.

One thing for sure, you should not compare the XBSX and PS5 GPU's as there are laid out different.
All XBSX CU's are grouped together.

 

[chilichote]

The I/O complex is probably on the opposite side of the CPU... two extremes... so I don’t believe the FPU is there because it could generate a big latency.

I just read on Wikipedia that an FPU is also possible as an independent chip. So I just speculated. Maybe it's a chip outside of the APU.
I have no idea whether floating point calculations are sensitive to latency.

 

[RoboFu]

Hopefully this will push Sony to explain PS5's hardware more clearly to put an end to misinformation and confusion.

Lol why should they? What would they possibly get out of doing so?

 

[MonarchJT]

Unrelated... you need just to stop to spread FUD the others didn’t said... you made up too many things in the last 24 hours.

I'm waiting for Locuza info about the dieshot

 

[FranXico]

I have no idea whether floating point calculations are sensitive to latency.

Oh they are. Very much so. Not in terms of accuracy, but as a limiting source of latency. Data locality is always a concern.

 

[John Wick]

It was never going to have 128mb of infinity Cache. There was speculation it might have 4mb of it. Just speculation but obviously some people can't help themselves......

 

[Md Ray]

Desktop Zen 2 and Zen 3:

XSX and XSS die-shots:

 

[OverHeat]

That thread is already delivering thx u guys

 

[Garani]

The FPU does not necessarily have to be installed in the CPU. It can also be in the I / O complex. Or, for reasons I don't understand anyway, Sony thinks it can do without it.

The FPU is there, just at 128bits and not the usual 256. Basically it has half precision.

 

[Lysandros]

This.

RGT more speculated about L3 cache of the CPU that is not even related with the Infinite Cache of the GPU.

Seems like Xbox fans uses Apples to talk about Bananas.

Yeah, he put pretty heavy emphasis to unified L3 for the CPU in mutliple videos but apparently his sources were wrong about the matter. Unfortunate.

 

[SlimySnake]

ok so in layman's terms, what am I looking at and why is this newsworthy?

This will confirm that RedGamingTech and other bullshit insiders were jerking us off all this time. No unified CPU cache (potential zen 3 feature), no rdna 3.0 features.

It will also confirm whether or not the PS5 is using RDNA 1.0 CUs and has more in common with RDNA 1.0 than RDNA 2.0.

I'm waiting info about that because i been muted just for this reason

Not saying he is right but the die shot won’t confirm or deny anything he speculated in that twitter.

 

[SlimySnake]

The beauty that kicks a 12 TF console ass performance-wise in the naked. I love it

lol it's keeping up with the 12 tflops gpu and in some cases outperforming it by a small margin, but i wouldnt say its kicking its butt.

 

[MonarchJT]

Not saying he is right but the die shot won’t confirm or deny anything his speculation.

he is making up stuff ...just don't talk about that site/youtuber as something to take seriously. topic closed. so wanna do a bet with me about the arch?

Cerny and Lu (AMD) said it's RDNA2, so the CUs are RDNA2. There would be hell to pay in the courts if not (market abuse, false statements, etc).

 

[SlimySnake]

lol i cant believe I forgot about this. Its shocking that they did this at all. made me think that the breach was far worse than they let on.

 

[S0ULZB0URNE]

So it's missing the DX 12 parts and has a touch of RDNA 3

The CUs are RDNA 2... Cerny said that in March.

 

[azertydu91]

It feels like people lacks nuance nowadays,like an insiders said it has supposedly some zen 3 features and some people hear it is full zen 3 but in reality you can have zen 3 feature(s) without having a full zen 3, it just helps a bit.
Exactly like sfs can helps diminishing the use of ram but you don't have twice the ram, it just helps a bit.
But it is surely easier to fight with PR words and oversimplifications throwing all the nuances out the window.
Just as it is easy to just think someone is a warrior from the other side and is therefor(e?) wrong.
And I do understand the irony of using simplifications to explain how people oversimplificate.
But who want that grey area shit when you can look like you win with simplifications?

 

[MonarchJT]

this is absolutely true 100%

 

[John Wick]

It was never gonna be 128mb. Probably 4mb of L3 cache which was pure speculation.
