thats because they are ports, they are made to look identical. "adding also that the Ps3 chips can only used 256mb ram max when the Xbox 360 chips can use a full 512mb of ram if needed.." and no,the ps3 have 512mb ram to but split you think 256mb goes unused?! the ps3 have GPU DDR3 700mhz ram, 256mb+ 256mb XDR rambus 3.2ghz that can be shared!. the 360 have 512mb shared between gpu and cpu like integrated card. in 2009 both cards are considered low end, but both gpu may outperform similar spec PC Gpus due windows not being a bottneck.
ps3 RSX have more raw power potential. but "The efficiency is based on the fact that Xeon uses unified shaders architecture, which allows it to use the pipelines for either vertex/pixel shader calculations, so when pipeline is free it can be used by either." |
If we are talking theoretical numbers... then the GPU in the 360 can theoretically perform at 100 percent it's theoretical limits. The best modern non unified GPUs do is 70 percent. As for the shared ram... No... that would be a waste... the amount of time it would take to actually move to the CPU bus to utilize the 256 megs of xdr ram is insane. The GPU can only access 256 megs of ram at a time in a normal game.
