There is a problem with the comparrison. And thats the fact that the edram isent taken in account. While the PS3 has maybe 0.8GB/S more bandwidth, it cant not competed with the bandwidth that will be saved on the xbox360 thanks to the 10mb edram. Lets take AA as a example. Where the PS3 needs to constantly move data from its video memory, thus wasting its bandwidth, the xbox's edram performes this widout affecting the ram so much. Also z-buffer, and other thinks can also be done using the edram, all stuff that doesent need to go past the main bandwidth, and can be done with a 250 GB/s pipe. It's this what will save a lot of bandwidth on the main system pipes.
