ATI - PS3 is Unrefined

Jawed said:
Latest statement was that January would see a flurry of 90nm desktop PC GPUs, not including a high-end GPU.

Indications are that we prolly won't see a high-end 90nm PC GPU from NVidia until Feb/March.

Jawed

He doesn't state anything about the PS3 GPU but if that's true than I don't expect the PS3 before the summer. This is conflicting with statements other sources made though.

That looks like Dave's speculation. The quote just stated they'd have one or two 90nm parts by fall. Who knows, maybe he was referring to the 7300 go or something. The most obvious indication that there were no plans for a fall refresh on 90nm is that they didnt go for the 110nm gold with the original GTX. Why leave so much room on 110nm if you're planning on 90nm for your next part?

What do you base that on? The fact that they released a faster 110nm part 6 months later? That could just as easily support Jawed's assertion that they are having trouble at 90nm that they had to fallback to something else.

They didn't leave any room on 110nm - 7800GTX-512 isn't a viable product, just a few thousands boards for the purposes of marketing.

Why work so hard when they can own so easily;)

The part about lower clocks is right, but I'd love to know where the talk about SLI comes from. There's never been a CEB model with SLI. It's always been a single 4x PCIe slot across a bandwidth-restricting southbridge.
I can not filtrate all the rumors, you know. :p
I think it came from a misunderstanding (WRT to the comment saying that it was twice as powerful compared to the actual Nvidia top of the line. While it was refering of course to the early G70).
DeanA said:
That ain't true.. the Alfred Molina face demo and the exploding gas station one were both definately running in realtime, being controlled by Phil, as our group in SCEE wrote 'em.
Yeah, forgot about those, true.
Sorry for forgeting your work, Dean, but to my defense it was 4 in the morning when I wrote that. ;)
 
It's good to see that real PS3 developers are debunking what ATI said. At least NDA's don't get in the way of pure PR speak. It's also good to realize what we will have in store for us in future PS3 games will be remarkable.

I hope that's the truth.I'd like to see the outcome of this "console war",but from what we have seen in the near past sony was the winner having the worst hardware.So now that everyone sais that ps3 is slightlybetter or just equal to the 360 it should be a pice of cake for sony:D

Not followed this thread for a couple of pages, but what has been "debunked" other than what was said about the E3 demos?
 
Jawed said:
Bearing in mind that the graphics programming for the demo is the same on both PC and PS3, you can see why the graphics would have been relatively easy.

The tricky bit, presumably, was getting the UE3 engine code to run on Cell - presumably on PPE, perhaps dual-threaded on PPE.



Jawed

Doesnt Epic have a version of UT 2K4 for the MAC? Wouldnt using that code make running it on the PPE much easier? Nvidia also makes their GPUs for the MAC line of PCs as well. Maybe there wasnt much work going from their PPC version to PS3 devkit which makes 2 months much more understandable.

I don't think it takes a company like Nvidia some 8 months to glue the flexIO on a stock G70 (which taped out in..march?)
Are you suggesting that G70 taped out in March? Because if so, thats far from the case - I would estimate that initial tapeout would have occured late Q4 2004, with a fair amount of time prior to that to account for the design change to the ALU's (although much of the 110nm porting would have already been accomplished with NV44/NV43/NV42, so that work was already done).

The 90nm 6100 and Go 7300 did launch in that time, but then the 7300 was somewhat of a stealth launch and not really volume until they hit the desktop verion - I'm not really certain what is going on there. I'm not sure they planned a high end 90nm product before now, but my impression would be that ATI would have about a 6 month jump on them had R520 been were it was supposed to have been; wherever GTX 512MB came from it doesn't really seem like it has the volumes to last particularly long.

I'm curious as to what the "Type C" graphics cards in the latest devkits are now though - whether they are GTX 512MB's or 90nm parts (but not, b the sound of it, RSX).

I know those first two parts were launched but the 7300 is that for OEMs only cause i havent seen any?
 
7300 was already announced by ASUS as the Go 7300 in one of their notebooks. I don't know if the notebook is available now or not.

The following quotes have been debunked in one way or another.

it's essentially a PC graphics design bolted on to a Cell processor

He makes it sound extremely to simplistic. "Bolted on"

Well, yeah, but the tragedy is that it is unrefined

but the movies were generated as movies and dressed up as: 'This is what you can expect from a PS3', but that's probably overstating what the PS3 can do a little bit. Indeed, it's well beyond what we expect the PS3 to be able to do

He breaks what we seen at E3 as either a real-time Unreal demo or movie that was dressed up as 'This is what you can expect from a PS3'. Well this is wrong. There were plenty of those videos that were running realtime and not like Killzone or Motorstorm.

That was pretty much it. We still don't know for sure if RSX was a last minute decision or how "unrefined" PS3 is/will be.
 
Whee! Eight pages because Richard Huddy likes ATI's/MS's design decisions better than NV/Sony's? Yeah, that's a shocker alright. How dare he.

Tho he prolly thinks he knows more about RSX than we do, and given how little we know, he might be right in that. Tho I'm less sure on the tradeoffs of specific design vs general design. But until we actually have more info on RSX, it's a pretty pointless discussion.
 
Dave Baumann said:

There isn't a lot of solid stuff there to refute in the first place. The E3 stuff seemed to be the meat of his argument.

He only makes one other assertion (the PS3 GPU is "essentially" on a PCIe bus - so far I thought the only thing we *do* know about the GPU is that it's been redesigned for the PS3's own bus tech... the same bus any other alledged chip would have lived on anyway) and the rest is "my console is better than yours" rhetoric using these random claims to prop it all up.

Now given that he's:

a) Talking bollocks
b) Somewhat biased

I don't really think his opinions are worth the bandwidth being generated.

I mean not even MS have recently tried to play the numbers game... it's all "it's about the games not the tech" or at best "PS3 won't be significantly better" - but here's an ATI guy suddenly claiming that X360 will actually be much better?

His arguments hold no water - he's sounding *desperate*.

So never mind what's been refuted - what has he actually said that's truthful or insightful and worth our time analysing?
 
Considering how close Xenos is to DX10 GPUs, Xenos v RSX is looking just like R300 versus NV20.

Unrefined is just the start.
