In the patent, it was prefered that each *APU* have 32 GFLOPs performance.
Not each PE.

There would be 1 PU/CPU per PE, and 8 APUs - which would give *256 GFLOPs*
per PE.

Then 4 PEs (256 GFLOPs each) are put onto a single chip to form a BroadBand
Engine. that is where the 1 TFLOPs came from.

The BroadBand Engine would be the main CPU of PS3.



Now in this new presentation, KK shows 1 PE having performance of 1 GFLOP.
this does not make sense at all. that's less than the Emotion Engine of
PS2 which has 6.2 GFLOPs performance.

The slides are 2-3 years old, that is why. they are the SAME slides that IBM
showed for the Blue Gene project, IIRC.


I wouldn't trust what this guy says. I've seen the original IBM image,
and it IS different. Subsystem, why don't you give a link to the
original IBM image, so that others can compare it with the slide?


Actually, It IS the same slide, So Sony Cell == Blue Gene ?!?
