I'm not sure they use "bits" as a measurement anymore...of course I'm completly ignorant on this subject so I couldn't say...always been curious though.NextGenNow
I think first we need to find how many times the PS3 is powerful than PS2, then times that number by 128 bits = PS3 bits i think. I was looking for that online, but I cant find the actual number, some are saying PS3 is 32 times more powerful than PS2 other are saying 1000 times more powerful than the PS2, so I really can't tell.
It's irrelevant at this point since no one seems to bother taking advantage of anything more than 64 bits as far as the CPU goes. The GC was technically a 64 bit system while the Xbox was a 32-bit system. Bits have meant virtually nothing ever since the graphics stopped being dictated so much by the CPU.
