WOW so CELL provides superior performance over a 35watt C2D T9800 processor? Must be why Pixar just anounced they are switching their renderfarms to all CELL, oh wait no they didnt they just anounced they went all Intel. You clearly are insane.

erm he clearly didn't say that, so does that mean you are actually bullying someone and picking on them for no good reason? shame on you!

The CELL has a theoretical performance cap that is reasonably higher than the Xbox 360's processor, though not significantly so.
Do to the nature of game programming, the CELL will only ever give the PS3 a minor advantage over the Xbox 360 for game software, and tapping the power necessary to display this minor advantage will continue to be prohibitively expensive and difficult for most programmers.
At no point will the slightly higher level of avaliable power give the PS3 anything more than a slight and immeasurable sales advantage over the Xbox 360.

They are as they can run independent of the PPE.With each SPE having it's own kernel, also own memory. SPE's are connected by a very fast inter-connect data bus, capable of transfering data between SPE's at upto 400Gb/s. SPE's are the raw power of 'Cell'. Each SPE alone can out perform a 360 core, by a huge margin. |
SPE`s have their own memory?
What have you been smoking, they dont even have cache memory and lets not even get into the rest of your clearly idiotic post.
Or urm, are you being sarcastic?
Online its sometimes hard to tell.

You keep mentioning 8 SPE`s for instance when I have mentioned several times before and even articles you yourself link to talk about 6.
You talk about theoretical limits based on 8 SPE`s while there are only 6 and even then theoretical limits can NEVER be reached simply because they are not standalone processors, memory and data has to be fed and cheked from the PPC core etcetera.

While you may be right, I'm not entirely convinced because of the fact that, despite the PS3's more difficult architecture and being on the market for a year less, it's exclusives are at least equal to and possibly better technically than the 360's exclusives. This would seem (to me) to indicate that the PS3 is more than a negligible amount superior to the 360, but it could be for an entirely different reason. However, at the present, I can't think of any other possible reason for this fact.
Not trying to be a fanboy. Of course, it's hard when you own the best console eve... dang it
the cell.... why is this even being asked? this is like comparing a Pentium 2 with a Phenom X4..

Sony dropped out of their CELL partnership so now it is owned exclusively by Toshiba and IBM. You wont see a CELL processor in the next Playstation, Sony learned a very expensive lesson with CELL.

That does'nt mean that Sony could'nt fund R & D for a Cell powered PS4. Sony still afterall have a licence to use Cell. Just cos they out source Cell production too Toshiba does'nt mean that Sony would'nt have any say in the Cell chip in the future. I mean Sony could get the likes of IBM or Toshiba to design a hybrid Cell chip just for PS4 in they wanted too.
@nnn2004 for your nvida/ati comparison, that depends heavily on software implimentation, on the mac side of things the gt 8800 is slower than the ati 2600. the ati 3870 destroys the 8800, being almost 50% faster at many tasks barefeats.com provides the testing.
@topic
basicaly for the cell to be more powerful than a tri-core powerpc processor, you need someone to program very well for each of the spes if that is not done, the tri-core will win out due to all three cores being able to due to same quality work on the same data, the spes can not do that, they need direction from the main core. the spe shine when someone takes the time to write out code that optimizes for it, the tri-core should not need the same level of optimization, really if you develop for ps3 first you would have to de-optimize it, the best example i have of this is on mac when the shift for powerpc to intel took place, photoshop cs1 was optimized for alvatec a speed boost powerpc tech, when moved to intel it was deactvated, and a special patch was issued to try and regain some speed... though it was still much slower on new intel chips than on three year older powerpc chips.
alvatec is a very similer idea to spe. though at most you saw two alvatec threads on any powerpc chip. if it is taken advatage of it can be very useful and give all kinds of really cool gains, but it is hard to program for and has only specific uses (or per spe in the case of cell). if not taken advantage of though the chip has no special qualites and depends on the power of the main core

Cool, so the wheels on my car are individual cars?
Awesome I have 5 cars now and a spare one in the trunk.
@MikeB
The basic principles remain the same. It's not like if you have been doing one or the other your hands will be tied in terms of competence. Just use the Cell a little on a PS3 running Linux, you have absolutely nothing to be afraid of.
o.O , if I recall right. PS3 linux is running only on PPE(Correct my, if I am wrong.). The basic principles are nothing like same. Cores in PC can do everything with ease, you can split any work easily between them & so on. You really can't do that with CELL.
Very unlikely, a heterogeneous design provides significant benefits with regard to performance and efficiency. IMO by the time the PS4 launches the bulk of current PS3 developers will be fully accustomed.
Maybe in theory and as a hardware, but just think about development costs of programs...
And about those costs of components,

@NNN2004
Well, I am a programmer, but I really don't have any practical knowledge about CELL.
(If anyone of you wish to give PS3 for studying purposes, I am willing to take one and make programs for it. ^^)
