Well..the author should come here, read the forum, and gather some more information he still doesn't know :)

Nobody knows for sure how many PE's the CELL chip in the PS3 will have.

Lots of people know whats the CPU configuration of PS3 is like... Maybe not the general population, but its not exactly uncommon information.

Anyway the article is also fundementally wrong about GPUs vs Cell, they are not fundementally the same.

Hehe...this is one greatly kept secret. Everything in this project is. Hell, they had signed up with nVidia for an year and a half without anyone knowing it! My guess is that everyone that knows about the PS3 is currently locked up in one of Sony's dungeon somewhere. ;)

if this is launching in the next 12 to 18 months you dam nwell better hope the devs know about the cpus and the gpus by now otherwise those are going to be some fugly video games at launch

Mostly old information, some bad speculation, and largely an anti-Wintel <bleep> rant.

Nothing that hasn't been said here 100x over.
Best summary of the posted article. Sir, you have have my most sincere commendations.

Yeah, if LOTS of people know the CPU setup, more than we've been speculating here, then yes, it's one hell of a well kept secret.

Re: the CPU configuration of the PS3, all that is really out in the public domain is the patent. And the patent would seem to indicate 4 PUs. AFAIK in going from patent to PS3 reality, everything floating about in the public domain is rumours. While scaling back from 4 to 2 to 1 PU is entirely plausible for instance if lithography doesn't develop as per expectations, it is almost impossible to judge from the rumours alone, even if we assume that they are correct in their claims, if such a scaling back has been made for the purpose of getting working silicon out, or if a reduction in processing cores has been decided for the actual final shipping product.

I'd assume that there are people who know, but I'd also assume that there are tiers of information even among those who are under NDA, and that not everything is known even to for instance developers until fairly late in the game.

Scaling back from 4 to 2 would not surprise me in the least if Sony feel in any way pushed to get to market. A further reduction from 2 to a single PU would seem quite a large step, more even than being for instance one lithographic generation behind would mandate. Still, going to a single PU would reduce complexity, potentially reduce power draw simplifying the overall console design, increase yield per wafer, and lower costs. But it's very difficult to credit the rumours as being authorative of the final design, and know for certain that they do not pertain to either prototypes, or initial programming model information going out to developers.

I haven't broken an NDA yet though, so if someone in the know would like to PM me.... :) Nah, its not worth it, I'm just being curious. From a computer architecture standpoint, it would really be a pity though if the PS3 only embodies a single computing Cell, as the concept thrives on the idea of very large number of them.
 
What did you guys think about his comments on the hardware DRM? I haven't been keeping up with things as well as I'd like. I'm not terribly pleased to hear about it. :/

thank GOD that both ISSCC and 'PS3 Premier' are only a few weeks/months away. they should both put an end to at least some of the speculation that's been going on for 2 years (cell patents) and actually...over 5 years (Sony's first comments on PS3)..... ....

Right.

Because then the platform contention will end and the fanbois will disappear. :D

What type of utopian dreamland do you live in?

Anyway, it looks like this article has been picked up by a lot of other places as we are getting shitloads of referals from it to our DX Next article featured in the Bibliography.

:oops: We're famous!! We're famous!! ;)
 
My guess is 1x8 for the PS3 as well. It would simplify the software developement versus multiple PEs (since there is a central control processor).

Is there any technical reason why they couldn't use 2 Cell chips at 90nm initially, putting both PEs on the same die at 65nm?

Yes and No.
IBM has a lot of MCM (MultiChipModule) experience. More than anyone I can think of. Of course it could be done. They could put four PEs there as well and then progressively shrink it.
But.
The cost would be prohibitive. The only reason to do it would be if you just couldn't fit the whole thing on one chip, and IBMs limit there has been 400mm2 for a single chip. Thus, for this to have meaning, the individual chips would have to be in excess of 200mm2 + additional real estate for the inter chip communication. Compare this to for instance the 60mm2 of the 970fx. So the chip cost would be high, and you would have to add very significant packaging costs. This would have to be one heck of loss leader, and soaking up the costs over the initial buying frenzy would be painful in the extreme. Further, you would have to design the PS3 around the size and power requirements of this beast, adding cost and bulk to the entire package.

It just doesn't make sense. It might make sense to do something like this in order to seed to various development houses, library and tool writers, et cetera. But for a production PS3 the concept I can't see that the concept holds water.

The price tags of an 8-way Power4 and and a PS2 are just too different. :)
