You got me there. Idk 

I would like to see the article stating that 3 cells could be overpower by a single GPU.

quoted from acrticle.

"The new performance claim by Sony is that the CELL processor in this configuration can achieve a rating of 218 GFlops at 3.2 GHz."

Note I ignored the fact that the article states that actual performace is LESS.

http://en.wikipedia.org/wiki/RSX_'Reality_Synthesizer' (cause I'm lazy)

1.8 TFLOPS.

The GPU performance is of course specialized but that's the point.

Edit-Hmm, maybe I shouldn't use FLOPS like this. Oh well, too late.

off topic....but could they have instead included multiple RSX chips and no cell instead of no RSX and 3 cell chips? Or is using a GPU for CPU purposes to hard to develop for? IDK just curious

Gpus are specific to graphics while cpus are in general. I think it would have been better if they used the money they had for the cell, and just added two rsxs , and a dual/quad core cpu. That would have been easier to develop for , and better imo.

The Cell is very usefull for pre-rendering computations (ie generating geometry shapes for water ripples , particle repulsion and interaction etc- etc ) also Physics , colision detection and ray-tracing (still not fast enough for real time tracing though) And Digital Signal processing (sound , and video) -

These are all things cant be done with a GPU and are slower when done on a CPU the PS3 has alot of scope for future gameing , there is a longer learning curve and larger tool, library development cost associated with it but it can go places where the rest cant follow.

The X360's CPU is a Compromise between the Cell and a Normal Power PC (like the Wii Uses) - so it also has many complexitys to deal with (like multi core and SIMD).
I Think there are many games on both Xbox360 and PS3 which are only using a single core - that is often all they need. !

here check this artictle out saying that gpus will be replaced by multicored cpus

Cell can and will make a difference, its not all about the gpu in the ps3

 I loled, and a lot, intel right now is in a hard place in the graphics area, yes, their CPUs are great, but their IGPs are lame...

Read the article again, incomplete demo, no info about the FPS or resolution, they are just promoting their CPUs... (And trying to discredit the madness of the multi-gpus, mostly for troubles with nVidia, SLI tech and Havok vs PhysX)...

Overcloking a CPU has a little effect in a game vs adding a good GPU...
