My guess is that the speed of the Cell allows for better bandwidth use of the texture memory (since the other aspects of RAM, like size and speed, are fixed). This may not be the case with the frame buffer, which had to be reduced to make room.
So the things that are slightly better are part of the texture memory, while resolution is part of the frame buffer, which is not part of the memory of the 360, and thus slightly higher on that system.
In other words, it supports my claim that the 360 actually has a better frame buffer, but that the PS3's texture memory may be better utilized.
A flashy-first game is awesome when it comes out. A great-first game is awesome forever.
