Saw this story over at eetimes. What are your thoughts?

IMO it looks underwhelming for four main reasons:

1) It uses 287.5 M transistors?!? And takes up a die size of 462 mm^2 with a .18 micron process?!? How in the hell will they ever produce this chip in volume even with a shift to .15 or .13?

2) 32MB of memory seems like a fair amount now, but it will be out in 2003 at the earliest...

3) 75M polys/sec seems like a fair amount now, but 2 years from now... Also, this figure is probably a theoretical best case, who knows how many polys you can actually push with all of the features turned on.

4) 1.2 - 2.6 GPix/sec, see 2 & 3.

The embedded DRAM is a major plus for the bandwidth it provides, but this chip leaves me with more questions than answers...

I don't think this is a PS3 chip. 75 mpps seems too small to me, for a chip that in a system 5 years away.. I think this chip is designed for other applications.

chances are its going to be used in the GSCube, Sonys CGI rendering workstation, currently the system uses 16 Emotion Engines and 16 Graphics Synthesizers.
