I think the PS3 version will outperform the PC version if we compare performance from the perspective of someone who appreciates the power of the cell.

 

na, the amount of memory and the difference in graphic chip performance are quiet big at this point, you don't need a CPU as powerful because your video card is doing a lot of the work, not to mention the new quad cores are pretty beasty by themselves.

 

 

He's being sarcastic mate :)

The PC graphics cards are 2 generations ahead of the PS3, nearly 4 years (long time in PC world) Memory is basically unlimited (I have 12GB in my PC). Most gamers have at least 4GB. The Cell is nowhere near as powerful as even an old Intel Q6600, would wipe the floor with it in all but the most 7 thread optimised applications...which don't actually exisit for normal people.

You aren't basing that on facts and that's why you are completely incorrect.

Example: Intel Core i7 965 XE inter-core bandwidth + cache & memory bandwidth = 106GB/s

Cell inter-core bandwidth ALONE = 197GB/s (observed)

"The IBM Systems Performance group has demonstrated SPU-centric data flows achieving 197 GB/s on a Cell processor running at 3.2 GHz so this number is a fair reflection on practice as well."

 

That doesn't have much to do with how powerful the CPU actually is, they are built for different things essentially, while the PS3 Cell's memory bandwidth is pretty good and it's built for floating point operations, it runs on a piss poor PowerPC CPU with 7 SPU cores that doesn't support out of order instruction execution and a pretty bad branch prediction. The core concept of the i7 is very different from the Cell and it's not really up to compare in essence.
