Overall results demonstrate the tremendous potential of the Cell architecture for scientific computations in terms of both raw performance and power efficiency," the authors state. While their current analysis uses hand-optimized code on a set of small scientific kernels, the results are striking.
On average, Cell is eight times faster and at least eight times more power-efficient than current Opteron and Itanium processors, despite the fact that Cell's peak double-precision performance is fourteen times slower than its peak single-precision performance. If Cell were to include at least one fully usable pipelined double-precision floating-point unit, as proposed in the Cell+ implementation, these performance advantages would easily double.

That article might as well have been written in gibberish

the title of this thread is misleading.

the artichitecture. that's what it's talking about. The benefits of stream processing are very promising. That said, the actual cell processor that is contained in the ps3 isn't at all the super computer we would like to believe.

did they not just say a little while back that they are finding it hard to mke large quantities of the cell chip or something so they will be making slightly less in something.

Yes, the latest news was that the cell yields were less than satisfactory.
when did you get back?

the same site that said cell yields are in the toilet are now saying that IBM claims cell production is on track:
"THE CELL PROCESSOR is steadily being shoved out the door of IBM plants, despite reports of poor yields.
Sources have informed the Inq that IBM executives have told employees within the firm, that yields are "on or above" targets.
Yields for a large, complex part like the Cell are expected to be low at the start of production and improve steadily thereafter - if IBM had allowed for a very low yield to start with, its plausible that the rumours of bad yields were entirely accurate and this is what IBM was expecting all along.
The exec also said IBM had shipped the first full allotment to Sony under a 'take or pay' arrangement (whereby Sony has the obligation of either taking delivery of the goods or paying a specified amount), and that Sony must have "quite a stockpile of the processors in a warehouse somewhere".
Presumably the warehouse has close links to Asustek, where recently other sources released details of Asustek plans to deliver 4 million units of the PS3 console to Sony this month."

Not sure why hades original article is so bad. That's a good and very factual article and there is no better source(for support) than the U.S. Department of Energy's Office of Science.That's a .gov site.
That means big things for ps3 not possible with the architecture of other processors in other game consoles nor pc's.We're talking huge performance leaps over what was originally supposed.How is this not news you guys?

"when did you get back?"
me?, if so, well i just got sick and tired of fanboys all around on this forum so i gave it a break. plus i ghot my HDTV and some good games on the xbox 360, so i was more into that.
"How is this not news you guys?"
i heard something like this a while back from one of the developers, he said the cell will do things consoles could not dream of at the momment, but after giving it all the prais he also said that the ps3 would not really use the full potenial of the cell and that when the ps4 would come out that it would be better used, so stuff they are saying now about the cell may be true but may not all be done in a ps3. (just my opinion)

"I heard this rumor as well, from my friend's neighbor's gardner's, landlord's stepson from his 3rd marriage. It must be true"

A CELL IS A CELL IS A CELL...
Anyway you slice it's still a cell.I don't get how it's not going to use it's full potenial.It's been in development for 5 years.A ps3 console is like a pc it has a mobo,gpu,cpu,hdd,etc...I don't see anything holding the cell back.
You may have it confused with the 1 of the 8 spe's that will be disabled.Last I heard it was reserved for redundancy tasks which is good because that would put less strain on the cpu as a whole.I haven't checked in on that for some time though so I could be wrong.

Actually it's there to improve yeild. If one of the spe's is bad they can still put it in still and whatever whatever whatever.
Just read this:
Quote:
Only seven SPEs are active; the eighth is redundant, to improve yield. If one of the eight has a manufacturing defect, it is disabled without rendering the entire unit defective. Additionally, one of the seven active SPEs is reserved for use by the system's OS, leaving six SPEs directly available to applications.
thanx once again wiki. Here's the full article if anyone hasnt read it recently or any at all http://en.wikipedia.org/wiki/Ps3#Launch_games

Thank you.Well hey if it improves the yeilds then great.
It's to bad we can't get all the spe's though.Ahhh well.

Your welcome it's what we're all here for ;)
I think all the spes should be active if they could have gotten the yields at good levels

Explain to me then how a cell isn't a cell and what will hold it back.
I could be wrong,I just don't see anything holding it back and no one will explain it to me.

Well there are alot of factors face.
The speed of the spes
The amount of active spes
The performance of the ppe
The use that the cell will be put to
The amount of knowledge possessed about the cell by those creating applications to run on it.
Also the amount of cell chips in a machine. Remeber the cell was designed to be used in a multi cell system where you have multiple cell chips working simularly to multi processor servers but in one device
