Dude for the last time change your Damn font color

I like how one text is white and the other is grey. Lol

Yeah, DemonCleaner DemonCleaner , you should really stick with the standard font color for those of us on the DarkGAF. You make good posts, but it's difficult to read.

A lot of tech sites picked up the story about the Sapphire rep. I'm really curious about CU count and power consumption. I wonder if it will be like 390/390X or X1X where it's 40CU/44CU. It's gonna be fun to see how AdoredTV's charts pan out in comparison what the rep was saying.

duders chillex! im not doing this on purpose. i have to use IE at work [for reasons]. it seems to do that as soon as you copy paste stuff around. go complain at the admins...
 
Increased slightly at 7nm due to it being a new process, nowhere near double.

Yeah i expect 60 to 56CUs depending on yields

if the 8SE rumour is true it's pretty likely they would go with 56 CU (64 minus 1 dissabled per SE) for yields

Yeah it could go either way 60 or 56 depending on yields by the time PS5 enters manufacturing.

i don't think you can have SEs with different amount of CUs. so if it indeed will be 8 Shader Engines, they must dissable 8CUs at a time.


cheers!

What are you talking about? This already happens with 56CU and 60CU cut down Vega designs with 8CU and 12CU respectively
Or am i missing something?

you re missing the rumour that navi now has 8 instead of 4 shader engines … from like yesterday ...you still remember?

if you want to dissable CUs i think you have to disable at least one per SE. 4SE => 4 CUs disabeled 8SEs => 8CUs disabled

But even doing that you are left with uneven CU per SE counts on Vega
60CUs-> 1SE with 12CUs and 3SE's with 16CUs each
56CUs-> 1SE with 8CUs and 3SE's with 16CUs each

Are you sure you have to disable CUs in multiples of the SE count? got a link or something i can read to understand this limitation?
 
im not sure on that, that's why i wrote "i think".

60CUs-> 1SE with 12CUs and 3SE's with 16CUs each
56CUs-> 1SE with 8CUs and 3SE's with 16CUs each

radeon VII: 60CUs -> 15CUs per SE
Vega56: 56CUs -> 14CUs per SE

?


i think i have to check some block diagramms later :-X

radeon VII: 60CUs -> 15CUs per SE
Vega56: 56CUs -> 14CUs per SE
Vega56 is just a vega64 with 8CUs disabled so the config should be 3*(16CUs per SE) and 1*(8CUs per SE)
i think i have to check some block diagrams later :-X
Please do and let me know, im curious too, i remember something about having CUs in multiples of 4, so you might be right. Im just curious how it works
ethomaz ethomaz care to chime in?

Welcome to the next-gen analysis/speculation and rumors thread. Next-generation chatter is exciting but can also be very confusing. I've decided to put all the gossip, and info regarding next-gen consoles into this one thread. That way we can thoroughly discuss and analyze every sort of information that is being fed to us, and continue to talk about these exciting times in a orderly manner. Thanks!

You mean the previous threads on the OP?
I was planning to order them chronologically, if you are willing to do it I'd apreciate it if you PMd so i can update the OP, otherwise I'll get to it on the weekend.

New day new rumors. I love it.
I am still somewhat SHOCKED that the absolute madmen at AMD want to name the next card RX 3080 instead of RX 680 just to annoy Nvidia.
But then again it would be a bit disappointing to see the RX 3080 being slower than the RTX 2080
And even funnier would be if Nvidia and AMD fight over the 3080 number

HOWEVER. I would not be really happy if the rumored RX3080 performance, VRAM and price are true, because that would be a bit lackluster imho. (though faster than RTX 2070 could mean anything ranging from 2% faster to close to RTX 2080)

Not sure but I believe it is like he said.

Vega 64 is 4x15
Vega 56 is 4x14

I don't remember any chip with SEs with different number of CUs... I think it is for balance purposes.
Even PS4 was a 2SEs with 9CUs each.

Edit - Just to add more evidence PS4 (2x9) and Xbox One (2x6) diagram:
I see so there's some kind of virtual organization where the numbers of CUs per SE must be even
I was confused because in reality there will be one physical SE with less CUs than the rest (DISABLED)
Say a Vega56 in reality one of its SEs will only have 8CUs. Assuming all disabled CUs are from one SE.

or are CUs in Vega56 case disabled on a 2 per SE basis?

2 per SE in Vega 56.

I see, i wrongly assumed all disabled CUs where from on SE
Thanks for the heads up DemonCleaner DemonCleaner

Assuming the 8 SE rumor is true, we'll see 56CUs max on PS5.
BTW that is directly related to the number of CUs disabled in consoles...

XB1 - 2SEs, 14CUs, 2CUs disabled
PS4 - 2SEs, 20CUs, 2CUs disabled
Pro - 4SEs, 40CUs, 4CUs disabled
X - 4SEs, 44CUs, 4CUs disabled

You disable one CU in each SE.

Looks like Sony really have a Event near the E3.
Activison won't have a presentation in E3 this year too and they will announced the new CoD: Modern Warfare at Sony event that is the event of PS5 reveal.

But isn't that coming this year?
Sony event is this year and before new CoD launch in October/November lol

From what I got from the leaks...

- New CoD trailer near E3
- Activision won't have a booth or presentation at E3
- New CoD playable at Sony Event

Sony exclusive event will be like a E3 shows with PS5 reveal, PS4 last games, 3rd-party games deals.

Holly shit megaton if real, I wasn't expecting Sony to announce PS5 this year

Only PS4 gameplay most likely right?
Yeap... only PS4 gameplay I guess... maybe a demonstration for PS5?

But the rumors/leaks always put PS5 reveal at Sony event schedule to this year (early June).

Any history of the tweeter - background checks, previous etc .. !

So Sony isn't at E3, but they sort of are .. just happen to be having a press conference in the same city at the same time of year ?

Yeah I think that pastebin is legit and we'll get a reveal in June.

-PS5 official info from Sony somewhere around next E3(Sony will not be participating on E3),i'd say Q2 2019 small reveal

Excuse me I don't see how these tweets points at Sony having an Event around E3 (I am not saying that it isn't the case!) I just don't see how the tweets would imply that.
Or I am missing something or previous tweets I didn't see

Common sense?

New CoD launches in October...
Leaks said early June for Sony E3 (not only one... most of them)...

There is no way it is not around E3 the event... at least it is this quarter... Activision won't show gameplay/demo near the launch of the game.

I see. I am just wondering how far in advance you would need to announce such an event to make sure people can register and come there and prepare for it.
The tweet says "playable at Sonys individual event" so I guess that means normal consumers can play it there, right?
But those consumers need to know when that event takes place and E3 is in like 2-3 weeks?

Somehow I expected a PS5 reveal event much later this year or even next year. The PS4 was first shown in 2013 the same year the console launched and fully revealed at E3 5 months before release wasn't it?
Would be surprising if Sony showed much of the PS5 (Or Microsoft for that matter) like 1 1/2 years away from official release.

About the games I can agree that they need some sort of platform for release date reveals. Though I thought they maybe do it with that State of Play thing now

But overall this is good news. Hoping to get release dates for TLOU2 and maybe Death Stranding

Wouldn't they want to advertise that by now or maybe send invites? They would want people to watch their streams wouldn't they? The more lead time you have, the more viewers you would get to watch.

Sony events are for Journalists, no?
I don't remember any Sony event for consumers.

Of course it will be streamed live to everybody.

Sorry no idea I never looked that closely into it being half a world away.
It would make more sense if it is for journalists only and them being under NDA for an upcoming event that we normal consumers know nothing about (yet).

Has anyone done the math for maximum TF if ps5 apu is 314mm^2 with 8core16 thread zen2 cpu @7nm?

  • I think TSMC 7nm should be 2.4x density over GloFo 14/16nm
  • Estimated Zen (not Zen2) size of a 4 core CCX unit is 44mm2 so should be down to 18.3mm2, so 8 cores =36.6 (call it 37mm2) [original estimate too generous] (note that doesn't include memory IO, PCI, USB etc )
  • Ignore Vega64 and VegaVII because they include extra fp64 stuff and are oversize for that reason.
  • At 14nm we get 32/36 compute units in 232mm2 (RX570/580), 16 CUs at 123mm2 (RX560), and 10CUs at 101mm2 - that puts CU size somewhere between 3.7 and 5.45 (very rough estimates) - this makes the extra stuff in a AMD GPU at around 36 mm2 (ie the IO stuff)
    • Alternatively subtract the 8 core size (88mm2) from Zen size (~200mm2) to get size of all the Zen IO stuff - that's a bigger number at 112mm2
  • So we've got at 14nm :
    • 88mm2 8 cores
    • 112mm2 IO
    • total 200mm2
    • scale to 7nm = 83 mm2
  • So the remainder for GPU is 314-88 = 226mm2
    • amortised (includes other stuff) per CU size estimate was 5.45mm2 at 14nm
    • so 2.3mm2 at 7nm
    • 226/2.3 = room for 98 CUs
  • Alternatively just take the size of RX 570 (232mm2) as being the minimum for 32 CU .. now a CU is 7.25mm2 at 14 nm, so 3mm2 at 7nm
    • 226mm2/3mm2 [size left for GPU / estimated size per CU] = 75 CU
;tldr - my worst estimate at 2.4x shrink from 14 to 7 nm is room for 75 compute units

The Compute unit size estimates are junk (I did them) .. and the scaling of 2.4 will probably turn out to be optimistic - but those are the figures we've got .. either way .. there's room for 64 CUs.

[edit - the other super rough way is to add the size of an 8 core zen and two 32CU RX570s both at 14nm - this is 200+232+232 = 664mm2 to get that down to 314mm2 need 664/314 = 2.1x shrinkage from 14nm to 7nm or better .. afaik we've got that]

So for TF - there should be the full 64 compute units - at around 1.25GHz this is ~10TF .. scale this to 1.6GHz and you get the magic 12.8TF figure (clock scaling from 14 to 7nm at under 1.3x seems reasonable)

The CUs become smaller with the change from 4xSIMD-16 to 2xSIMD-32 if true.

I just hope both consoles have some sort of blue light filter option like flux.
That's.... actually an interesting suggestion (although I hope you don't manage to summon "that one guy" to the thread), but I'm not entirely certain it'd be that useful. As far as I understand it, the melatonin-production-inhibiting effects are more pronounced at a closer range (say, monitor or cell phone screen), unless you are pretty much glued to to your TV I'm not sure if it'd make that much of a difference.

Do modern TVs have this functionality built-in? I know mine doesn't, but it's a couple of years old already.

Most modern monitors now do and some TV's I believe. But as I have a small monitor less than 20" as far as I know I can't buy a monitor that has a blue light filter option.

We're now up to 5GB/s on PCI-E 4 SSDs already on Ryzen 2 boards. The interface should allow just under 7 with overhead with the same number of lanes as current ~3.5GB/s drives. I hope we're able to get some testing of this PS5 Broadband SSD.
