PS3 Specs?

[Rob78]

I found an interesting post on the All X-Box Forums about PS3 and X-Box 2 specs,and I thought I would post it here.

And these are the X-Box 2 specs,again,I dunno if this is true or not

Possibly based on either:

IBM G5 PowerPC Processor OR
New IBM PowerPC Processor

Thats what I read,and that is word by word what they said,I don't necessarily belive it,but,I thought it was interesting.

No, that would all be bogus. None of that is official, and I've seen that posted everywhere. In a few months, we will get the confirmation from Sony that we've been longing for.

February 2005 is the date. They won't necessarily be talking about the PS3 [although it's a possibility], but they will be revealing specifications for the CELL itself.

For the Xbox2/Xenon, I did hear at least a few specs from a guy who had a developer box... 3 processors is expected, all right, but I didn't get anything about each being dual-core... Rather, the whole package is 3 cores, each one is 2-way SMT(or what Intel calls Hyperthreading), and 2-way SMT really only applies to scalar ops, not SIMD ops (it doesn't have that many extra SIMD pipelines), so the max FLOPs throughput is still irrespective of threads.

I was told that the clock speed would be pretty in line with PS3. Still, 65nm, 3 cores, PPC... I'd have to guess something like 2.4 GHz. Similarly, concerning PS3 -- If they manage to get the APUs running at 4.8 GHz, that's possible only because they'd be strictly single-issue, inorder, etc... you couldn't get away with 4.8 GHz on a complex OOO scalar/superscalar processor. Since the PU that schedules to all the A/SPUs is essentially a normal PPC, I'd expect that particular unit to run at half the clock speed... so the PU would still be 2.4 GHz in that case.

One thing I find strange in all the purported performance figures was the idea that 8 APUs per PE with 4 PEs yielded 1 TFLOP at 4 GHz. That all comes from the APUs theoretical limits, and completely disavows the PU part of a PE. So that suggests that the PPC core at the top does not serve any computational purpose, and is there for scheduling and distribution only.

A guy at ATI just the other day said that there are supposedly a couple of prototypes they're producing for Nintendo to evaluate, of various ranges of power and performance... it's rather unsure what would end up in the final box even now. Depending on the total power envelope, design, CPU constraints, etc... it's entirely possible that Nintendo's box could have a more powerful GPU than Xenon (and yes, there were a few prospective designs that fell in that range). But that would only happen if it was a fair bit lower than Xenon on CPU power (or at least CPU power _consumption_). Whatever doesn't make it into the two consoles would anyway end up affecting, if not becoming, further PC products, so it's no real skin off their noses.

XBox2 will be unveiled in January...possibly at Bill Gates' keynote speech at the Consumer Electronics Show on Jan 5th. And PS3 is supposed to be unveiled at the E3 2005 conference in late May.

And I don't think the XBox2/Cell chips are 65nm. I've read an article where Sony officially states the Cell will be fabbed on a 90nm process.

And I don't think the XBox2/Cell chips are 65nm. I've read an article where Sony officially states the Cell will be fabbed on a 90nm process.
We've all seen that. There are CELL units being produced on 90nm right now -- doesn't mean they'll always be on 90nm. CELL workstations that are available right now use these 90nm models, but that doesn't say much for the PS3. But the timing for both consoles would be well into the timeframe for a 65nm transition. There's no way that a high clocked PPC would fit within a small power envelope that is demanded for a console on 90nm.

As a parallel, Athlon64s/Opterons right now are primarily 130nm, with the 90nm units just coming out... the K8 design itself was inherently optimized for 90nm in spite of the fact that its first iteration was on 130nm.

I beleive this is in the wrong section. :) Moving...

box... dual-core...

PPC... etc... clock speed...



performance... etc...
Excuse me,but did you attend kindergarden?

What the hell are you on about Rob, and what point are you trying to get across here? There is nothing wrong with his spelling, and his grammar is fine too. Seriously it is a forum, not an essay contest. If you are unable to read/understand what he has written then that is a different story, but if you are picking on him because of the "..." in his post, then I think you have some growing up to do!

[kevindenoyette]

You'll do well here rob. Seriously.


Jackass.

Sorry guys,I was in a bad mood.So,can we continue to post on the subject?

[nesman]

These specs aren't far from what I had guessed. If these specs are close to the real ones then..... :shock:

Some of those ps3 stats were ripped from our site: http://www.psinext.com/information.php?sct=PS3#1

The important thing to remember is that very little is actually known regarding the PS3, as of right now the sepcifications at this link: http://www.psinext.com/information.php?sct=PS3#1 is only the best guess of what to expect and is not to be taken as official.

[Rob78]

Thanks Scott,I'll take a look at the specs on PSINEXT.
