Actually I have just read some article from forum (ps3insider) and they have more extra information on the Cell workstation info and I collect them in the following
( Warning !! I have not confirm these info from other source yet) :
1) there is 8 a single rackmount box in this workstation and each a single rackmount box can provide 2Tflops of processing preformance
2) CPU run at 4.6 Ghz(!!) @ 1.3V / 85°C (heatsink without fan)
3 ) Each Chip have 4 PE unit
Of couse, I will not excpect to see PS3 using a 4.6 Ghz chip...I thing 2.3 Ghz is a much more reasonable number on it.
