eDram on X360 acts like larger cache. Its only 10MB, but its also 10 times faster than regular ram so stuff you need more frequently with CPU or GPU go there while they are processing it.

As this thread popped up again I will correct some misinformation I posted. eDram isn't anything I wrote. Its made for postprocess effects like AA.

Because of the bandwidth savings and absolutely massive bandwidth to EDRAM, the Xbox 360 should be able to perform frame buffer effects like motion blur, depth of field, or lens flare with incredible speed.
