Some info:
RAM bandwidth plays a massive part in graphical quality. The PS3's ram can supply around 2GB of data to the GPU per frame in a 60fps game, whilst the Xbone's less than 1GB when there is no post processing done.
The ESRAM will help when it comes to adding post processing effects after the first render pass on the frame is completed by the GPU etc but it won't really help by getting more data to the GPU when the raw frame is actually being put together, apart from maybe the odd tweak here and there. Post processing as a second render pass on the frame can take a lot of frame time as it is GPU and bandwidth heavy so the ESRAM will definitely help there, but again the GPU is a big part of the equation in this, and its not like the PS4 will be bandwidth starved in this area either and it has a faster GPU to process the changes.
Its becoming a doubt as to whether the 360's GPU could actually process 1GB of data per frame anyway as its looking to become the bottleneck itself looking at the specs of it.
Games on the PC have regularly been hitting 2GB of unique data per frame at 1080p recently so you can see the logic behind the PS4's design, and the non logic behind the Xbox ones.
This is in basic terms of course as every engine is different in its hardware requirements.
