they are ways of optimization RSX sony created.
deferred rendering, which was used in LBP and killzone 2 works quite well.
and offloading work to the SPU to let the RSX focus on graphics like textures.
the ps3 have 512MB XDR 3.2ghz memory also and that doens't left unused.
actually killzone uses around 420mb
where the GPU uses 200MB + around OS and other things 200mb around
also the 360 GPU have it own bootnecks like HDR. which can be done up to FP 16 like in uncharted.
or doing 1080p because 10MB is not enough to display a image 720p antialiasing + HDR fp16.
its not bandwrith speed limit but size. u need over 30mb to do so.
both system would really shine with more RAM.
