Seems like a core part of the PS5s design is to bring in a ton of data from the I/O and to do it often. All these custom pieces of hardware is to ensure the performance doesn't tank every time the I/O is accessed.

Yeah, Cerny said it.

I think alot of people focus on how fast the I/O is but I think it's important to look at how the I/O affects performance.
keep moving the goalpost i don't care about that youtuber. we can close it here.
Is you that care for him so you can fill forum with some tales from HIS ass like rdna3 ...IC ..and all the others fud

Evidence about what exactly because what I posted is true.
If you mean Xbox 25% CU perf/clock increase from Xbox One X to Series X is the Hotchips presentation.
If you mean the over double digit CU perf/clock permanece increase for RDNA 2 over AMD RDNA it is the RDNA 2 presentation.
If you mean the 25% CU perf/clock increase for RDNA over GCN it is the AMD RDNA presentation.

It would be if the xsx used RDNA 1 CU but both are RDNA 2 CU and both boasts a 50% ipc gain.

MS confirmed 25% in their HotChips presentation.
They boasted 25% performance increase in CU perf/clock from Xbox One X (GCN) to Series X.
I’m not even sure where you are getting 50% lol

I think, and I hope it's not too controversial, that the coloured pictures are much better but they also remind me of gasoline puddles.
I think the new information is like a green potato chip. You've been loving eating your potato chips then you find a green one. You're not quite sure if you should eat it. But then you do, and everything is just fine.

But it was ambiguous if it was opposed to rdna 1 CU or GCN CU because if it was opposed to rdna 1 you are wrong (which I think is happening)but if it was opposed to GCn you are right.
Once again don't do like others are quick to do here and take one simple part out of context, but if you have a slide with explicitely stated 25% over gcn then yes I would admit that you are right.

Som people are living in the fantasy, would have been nice if Sony did also the hotchip stuff.... And now Cerny's conference was not that deep like hotchips...MS confirmed 25% in their HotChips presentation.
They boasted 25% performance increase in CU perf/clock from Xbox One X (GCN) to Series X.

Yeah, I mean potentially it could be hugely beneficial. I mean I guess the standard way of thinking is that performance is like a drinking contest where whoever can take the biggest, fastest gulps (of data) wins. This is like a funnel! Just open the throat and down it goes.

Definitely seems to be one of the things that Sony and Epic are betting on. Streaming in huge amounts of data seems to be what they are focused on. That could hurt performance whenever data is streamed in if you don't have the right hardware.
I guess we have to wait and see what these big data steaming games look like to see if it's worth it.

Quite a few warriors on here were touting an infinity cache.
Oh yeah? Well let me, I mean us, all of us be the judge of that?
Yeah. Didn't think so!

AMD ever say what happens to the perf/clock increase if the Infinity Cache is removed from the equation?
Yeah bro... i agree. It just found it weird to say something less capable is better because it’s cheaper. That’s just a weird take. You can say a hardware is great without having to down talk another.

I don’t think it will help but I forget to post the second Twitter he liked to me.I see some English words
In simple terms seems like Sony cut the non-used parts or the FPU and not the 256bits support.

Here is the official full HotChips conference for XSX. Of course, there isn't slide for every word they've said. It's impossible to make slides that much. LOL
But anyway :

Alright that's interesting but is in total contradiction with amd's RDNA 2 presentation about RDNA 2 CU's, could it simply be a mistake from the man speaking ?
Because I think otherwise their are only presenting the same gains from GCN than RDNA 1 CU's which means that it is indeed RDNA 1 Cu's (that I don't believe) r maybe that had to make concessions to fit that much CU on the die (I'm not sure about it either).
Honestly I believe this is a simple mistake made by the person speaking.
You can look for RDNA1/2 ipc gains slide from AMD.
Edit: Or it could be a scenario where we are not talking exactly about the same thing it could simply be a difference between theoretiical and practical gains.

You can't reason with stupidity.
"powered by AMD’s latest “Zen 2” and RDNA 2 architectures. Xbox Series X|S are the only next-generation consoles with full hardware support for all the RDNA 2 capabilities AMD showcased today."
A Closer Look at How Xbox Series X|S Integrates Full AMD RDNA 2 Architecture - Xbox Wire
We here at Team Xbox would like to congratulate and celebrate our amazing partners at AMD on today’s announcement of the Radeon RX 6000 Series of RDNA 2 GPUs. It was incredible to see AMD demonstrate the power and potential that the new AMD RDNA 2 architecture can deliver to gamers around the...

Nice comparisons showing the die shots of last gen and current gen.

I know it's not to scale but damn those CUs are much bigger than the PS4 Pros.

Sorry I missed your edit the 50% gains is from the AMD RDNA2 slides it stated :MS confirmed 25% in their HotChips presentation.
They boasted 25% performance increase in CU perf/clock from Xbox One X (GCN) to Series X.
I’m not even sure where you are getting 50% lol
GCN --->+25% RDNa1 ---> +25% Rdna2.Which explains exactly why sony CU's are a 50% boost from GCN cu's.

50% would be really insane jump....and I don't see it honestly, GPU is much higher clocked so that alone brings huge advantage over GCN, but on same clock, I don't know.

On AMD presentation they talk about “double digit” CU performance/clock increase from RDNA to RDNA2.
I understand “double digital” as bigger than 10%.
So if you take 25% + 11% (it is 11% over the 25%) that means 38% minimum GCN to RDNA 2.
AMD were not clear how much “double digit” it was.

I meant to say that Tempest is most probably a completely separate block inside the non-identified area, and not within the GPU area.
Like I said, that fact that the caches were stripped down means it may look very different to the CUs you see in the GPU portion.

That slide includes the higher clock on the left side... and the right side are the account of each part for that increase.taken from an AMD slide
Only 50% from these 50% come from IPC gains... that means 25%.
That is confirmed in the next slide:

So no extra L3 cache for the GPU/CPU, smaller FPUs, and what looks to be decoupled TMUs with ray tracing hardware.
I was firmly in the infinity cache or shared L3 camp so I’m a little disappointed, but not surprised.

That's a paradox right there, either they are too competent to make mistakes then they wouldn't have made the mistake to use rdna 1 cu's or they are incompetent and either misspoke or use bad CU's.
But in you sillogical propostion is a bit too reductive forgetting that anybody however competent they are can make on simple mistake or mispoke.Beside that engineer mispeaking falls in line way more with what amd said about RDNa2.

for rdna 1 yeah and they boasted the exact same gains for RDNA2.25 + 25 = 50%.That slide includes the higher clock on the left side... and the right side are the account of each part for that increase.

So why are the TMUs separated?

It is not.
Each CU is liked to it own TMUs in that pic.
The CU ends where start the TMUs.
Just like this pic.

Ok then it pretty much matches the RDNA2 CUs in the PC GPUs then. Cerny did say they were doing RT the same way as AMDs PC GPUs.
