[QUOTE="Amigwo"] [QUOTE="Verge_6"]Motion blur's pretty important for me. AA? Not so much.DanBal76
do you even know what AA is what what it does?
AA is more important for me. The reason why 360 games often have better anti-aliasing than PS3 games is because 360 has 10MB of memory dedicated to theGPU just to handle graphics enhancements, like AA. In fact the total memory of 360 is 522MB (512MB of shared memory and that 10MB just for graphics effects).
Antialiasing>motion blur. 360 games may have better anti-aliasing on average, but the 360 is not capable of better anti-aliasing than the Playstation 3. I don't believe any single game even utilizes the framebuffer for the intended "no cost" anti-aliasing
Unified memory is not as good as dedicated memory. It's simply cheaper. Example: low end PCs that don't have to render high-end graphics have unified memory. High end PCs have seperate memory pools.
Take a look:

"Sharing main memory with the display function reduces the amount of memory available to applications, and main memory is not as fast as the specialized video memory on stand-alone cards (see video RAM). See display adapter."
Video memory is faster (PS3), sharing main memory reduces the amount of memory available to applications (there goes the "522 MB" argument).
You will never have 522MB of video RAM available on the Xbox 360. The optimal situation is probably going to be 256/256 plus the 10 MB framebuffer which, in actuality, is not even linked directly to the bandwidth of the GPU and invariably handles minor functions.
Plus, the Playstation 3's XDR RAM dedicated for the CPU actually has higher bandwidth than the GDDR3 in the XBox 360.
