From what I have heard, around the Futuremark forums and other places. PS3's RSX is just a 7800GTX on 90nm. The Xbox 360's ATI GPU is as good/better as a x1900 XTX...so...which beats the 7800gtx.. And the cell is not 8 *true* cores. Its 1 fully functional core with 7 little cores which cant do much.
I am pretty sure it is 9 cores, based on 1 Main Core and 8 smaller ones.
As far as graphics, I can't say specifically which cards are equivalent, but I have been more impressed with what I have seen from PS3 than XBOX360 so far. I think that one of the functions of the smaller cells is that they can handle additional graphics processing. I am not too sure on that though.
