Also take into account that while a common target for eDram used to be the frame buffer, today's popular resolutions have grown too high to make it cost effective. Take for example 1680x1050x32bpp w/ NO AA, standard front and back buffer.... the front buffer alone is be 56,448,000 uncompressed. (56MB)
eDram is nothing but a waste of transistors for any decent size resolution, and therefore this looks entirely fake. The only possibility is that this could be closer to realistic now that transistor counts in the last gen have already gotten ridiculous, but I still don't think anyone would waste space on eDram for PC resolutions.
P.S. Both ATI and Nvidia designs have had L1 and L2 cache for quite some time now.
