I already said in my spec prediction PS5 will have hardware RT. They will probably have AMDs next year RT solution. Perhaps it wont be housed on special place on die, but in CUs themselves, which would probably make CUs even bigger then they already are compared to GCN, so on top of that I wouldnt expect double digit TF numbers.

Lol all over the place and sounding like a fanboy alarm went off. Sorry you got caught out there, i do that to many. Now sit down lol before the ignore button is hit. Power matters and just because you are trying to do mental gymnastic to protect your favorte piece of plastic, doesnt mean that power is irrelevant. Ability to play best third party is a nice advantage that this very forum pointed out quite a lot with ps4. Take care now 🍼
The irony of this post coming from you. Every thing you said describes you perfectly. You are a known extremely rabid Xbox fanboy. Come the f on.

Wonder how much MS realsitically expects Scarlett to sell. They have to know that getting PS4 hsers to move over is gonna be near impossible.
Who knows what their internal goals are. But gunning for #1 marketshare isn't always the case, nor realistic.

With the way digital revenue, subscriptions and cloud services are flying around (they even partnered with Sony), don't be surprised if overall profits are more important than getting most Xbox units (which probably don't make much profits for console makers).

If MS could snap their fingers choose between #1. Get billions of profits from software and sub plans only (no more hardware), or #2. Have a gaming division that makes hardly any money but is heavily focused on Xbox hardware out there, they'd probably choose #1.

But since there's no genie out of a lamp, they are likely gunning for #3. A combo of Xbox gamers with hardware, a push for digital heavy services, and more digital services being a cloud provider. If they can score tons of software/server/cloud revenue, it should lead to profits like the rest of MS divisions that are software heavy. And the gaming division wont have to rely strictly on Xbox units.

Seems like you guys are pretty confident with the 1.25x perf. over Vega.
AMD showed 10 titles Vega56 v Navi10 (10.5TF vs 9.75TF) with Navi having on average 30% better performance (some titles 25%, some 30% and some 40%). So I expect something around 8.5-9TF max for next gen consoles.
 
MS E3 2018 where they talked about multiple upcoming consoles?


Does Phil Spencer interview count?

Spencer has said clearly that technically the 1.xbox SAD and 2. Scarlett are this consoleS..

In this interview its not one word about lockhard.

Don't play stupid.
The truth is that Spencer said Consoles and internet idiots spread the lies about lockhard.

Who was the first moron on the internet which had used first the name: lockhard?!

He talked about next-gen consoles... you are playing dumb if you think SAD is next-gen lol

Sony isn't that dumb to say in advance that PS5 will be most powerful console like MS is saying for Xbox. It can be backfired later and Phil, Booty will become a subject for mocking over the internet. So, where is the demonstration for a fast SSD on Scarlett like Sony showed the Spider-man demomstration? Since you bitching about hardware RT, even though it is confirmed for PS5 via ND dev.
Also can be Xbox has more power and maybe even Hw ray tracing

Match the price at the same Time being more powerfull and Technical advance, also ms aquired top studios in the last Time! I think they are at least on the same level studio wise

They want it to be successful enough but actual box sales are not their main priority. Their main priority is to find a way to monetize you weather it be Console/PC/Xcloud/Gamepass etc...

Another thing worth noting is that currently, Xcloud is built with XBO S hardware. At the end of next year those Xcloud blades will be upgraded to Scarlett hardware. Point being that if they hook you into their services (Gamepass/Xcloud) then that Scarlett hardware (current one as well) will be used to monetize you weather you buy the physical box or not. Which is why they're so keen on emphasizing number of players, XBL subscribers etc...

If it is implemented in a similar way to Nvidia RTX. It would by my rough estimate take up ~10% extra space per CU (that's per CU not total die space). This is way less space than the changing to 7nm/+ would provide and shouldn't impact the TF numbers that much imo.
 
While what you say is possible there are a few problems.

~1680mhz is between the "game clock" for the 5700 and 5700XT.

Do you really think a console is going to be clocked the same as a dGPU reference model? That's difficult to imagine. Possible, but difficult to believe.

IMO Navi in the PS5 will run at below the base clock of PC GPU Navi. 1.4GHz probably, 1.5GHz tops.

Also at 40CU the 5700XT is already drawing 225watts ( and I bet it exceeds that under full load ), we will see soon. So if we add another 16CUs the power draw is going to be north of 300 watts for the GPU alone.

How does a 300+watt GPU (GPU only) fit in the heat/power envelope of a console? Add in an 8 core CPU and a PCIe 4.0 SSD, blueray drive etc and we're talking possibly north of 400 watts.

At this point Navi has been revealed and we now know that Navi doesn't clock as high as we were hoping and it's obviously not as electrically efficient as we were hoping either.

So while your math does add up and there would be no problem building a PC GPU with the specs you describe, the power it would consume and the heat it would produce make it unsuitable for a console.

Maybe @1.4GHz Navi becomes a lot more efficient but then that's going to lower the TFLOP count by quite a bit.

Also what about cost? I see you talking about 72CUs at lower clocks to try and make the math work, to get as high a TFLOP count as possible, but the 40CU 5700XT is $450. What will a 72CU Navi cost?

Do you really see the PS5 GPU having 72CUs?

i think you generally made a thoughtful post here, but the highlighted bit is off. you see the 5700XT should and would have been a $300 card if we wouldn't live in a post nvidia idiocity world. 250mm² die area even on expensive 7nm shouldn't result in die cost above $80 (absolutely worst case).

on how to fit horspower in a small power envelope you answered the question yourself: you take as many CUs as economical viable and clock them relatively low at low voltages.

and thats excactly what the console manufactures seem to be dooing: some people made a die size estimation out of the project scarlett trailer and that gave 400mm².
i hoped sony and ms would go with a MCM approach (GPU/I-O/CPU) this time around to keep prices low. but there still seems to be some challenges left with this kind of design (preventing that for now).

still, with a launch price of $499 there is nothing preventing them from going with a 400mm² monolithic APU even on expensive 7nm. worst case for that is that they will sell at cost (provided there are no cracy peripherals).

36 - 44 CU max in a console package. 36 being lower bound s, 44 high, 40 with ray tracing hardware taking up space is acceptable. Clocks my guess, 1,5 GHz - 1,6 GHz .

PS4s dominance this gen would have probably been considered impossible if someone predicted it in 2012-2013 on the heels of an incredibly successful 360 run.

I agree that it will be extremely difficult but all it takes is for Sony to get complacent. MS will certainly bring their A-game, as they did with the One X and have been doing with their services. Could xcloud+gamepass+plus a well-built (one x like) console be enough to balance it out this gen? I think its doable. But the real kicker would be for them to undercut sony on price and take the hit.

hard time believing MS would go from 40CUs to 44. i say 56 is the lowest. even with the higher clocks. and quite frankly 56CUs @ 1.8 and RT on top of that is more than enough.

Poor DF not inside info to make videos about next-gen... neither MS is using them for PR and Sony choose Wired over them.
Nobody has really proved to have any legit insider info. Shouting "I heard PS5 is more powerful than Xbox" or other way around sounds like clueless reporters trying to pretend like relevant insiders. 5 year old can make up that kind of rumor. Wired says nothing new that screams "insider info". Just repackaged same staff that's already out there.

At least DF is making educated guesses with information available.

I wonder if AMD can tweak their CU units a little to offer good RT acceleration. Separate RT cores take up a lot of die space while RT will be not always used in games.

It wouldn't make much sense for CUs to be chewing through their tasks and then each have to get inline waiting for a limited number of separate RT cores.

Wired info was official from Sony/Cerny mouth.

They referenced Proelite from B3D and the measurements he did. Congrats bud.

If you've been keeping up with this thread and reading B3D, then there's not really anything new in the DF vid except some minor details on press meetings.

Sounds like there's a bit of a conundrum with marketing power via the traditional TFLOPS metric, especially since they were so heavy with pushing 4.2TF and 6TF with the mid-gen refreshes. If they say "8-9TF! of raw power", people will think old GCN FLOPS instead of RDNA. My feeling is next-gen marketing is gonna be banging the SSD and RT drum, and as they test the market the "loud minority" of hardcore gamers will focus on shiny shit so RT somehow becomes the next-gen marketing gimmick...hopefully not. 60fps is where it's at.

I'm staying with 36CU @ 1.8GHz, 16GB GDDR6, 4GB DDR4, 3.2GHz 8c/16t for PS5. Scarlett would be 44CU @ 1.6GHz, 18-20GB GDDR6, 3.2GHz 8c/16t. They'll probably strip some of the L3 cache in favor of more room/budget for RT/ML cores. *Pulled from my ass guess* is that Sony will be using hybrid/shader based RT, while MS goes for full fat RT/ML cores. Just to be on the record.

So MS was thinking about Lockhart and anaconda as a 2 SKU launch per rumors. What would a dev kit setup be like for multiple skus? Would it be spec'd to the lowest SKU to be sure the games ran good on the weaker hardware? Or would it be spec'd for the stronger SKU?

Specced for the stronger and with developers settings to emulate the weaker?

Physically the stronger SKU with a software toggle to bring it down to the weaker, surely, as the architectures would be the same otherwise. No way they would have just shipped the weaker one with no way for devs to see their enhancements for the stronger.

*Pulled from my ass guess* is that Sony will be using hybrid/shader based RT, while MS goes for full fat RT/ML cores. Just to be on the record.

I'm finding it hard to believe that while launching the same year as next gen RDNA, concurrent to Scarlett, and being the first to mention RT at all, they would miss out on the hardware based version of it in next gen RDNA. They'd know the roadmap before any of us did.

Do you also feel Pro and X are gonna be the real true stars and winners for next gen getting most of the games for the next 3 or 4 years and running them at 1080p and sometimes better?

I'm sticking with Sony launching Spring 2020, especially with Last of Us 2 being pushed to Feb 2020. My assumption is the game was pushed back so much to get it ready for PS5.

Nothing actually changed as 8-9TF RDNA is equivalent to 10-12TF Vega 56 - Vega 64 performance wise. Only those chasing headline TF will be disappointed.

Since the unveil of RX 5700/Navi 10 we have known the consoles will come in <10TF.
Its more like 8~10TF
Some really read indeed:
With Navi, AMD takes the existing GCN compute unit and morphs it into the 'dual compute unit' - doubling up on ALU power while reducing latency and boosting cache. AMD is talking about a 25 per cent increase in IPC for Navi, which is equivalent to the boost delivered by a notional 80 CUs compared to 64. There is room to scale up further too, and AMD is expected to deliver a bigger, more powerful Navi GPU next year. All of which is to say: once compute figures do emerge, expect them to be lower than you might think, but rest assured that Sony and Microsoft can both still deliver great boxes.
