It would be so unnecessary that even PCs wouldn't catch up to it for a long time. That's ALOT of edram! The fact that you would even entertain such obvious bullshit shows you don't really know what you are saying. That site has already been deemed unreliable BTW.

Look, I am simply calculating the manufacturing costs (and, like it or not, I _have_ enough experience in that regard) from the assumed specs given in the op. Nobody says these are "the specs" (and my estimates would indicate they aren't commercially feasible). None of your answers have anything to do with this thread or my answers. Just a few things so that I didn't waste typing time:
If MS continues with the eDram design trick on the next Xbox, they will have to increase the size to go 1080p. As you can see, my estimate shows that it won't be 100mb. Whether they retain eDram or not is a question on how powerful the GPU will be. If the new GPU is powerful enough, they can drop the eDram trick and save a large sum of $$. If they figured out the eDram trick still gives them an edge, they will use it again.
Your dual "PGU" bit is so obvious I didn't even mention it at first. Way too expensive - you either pay for glue logic (two chips to same ram) or for ram (2 chips to 2 rams as in the dual PC graphics boards). However, it is entirely possible that early developer units come with a dual GPU layout - just because the manufacturing process for the new GPU (whatever it will be) is not yet ready, finalized or simply doesn't work properly yet. AMD mentioned years ago that they would be going away from the "Monsterdie GPU" to a scaleable assembly of small GPUs (on one or multiple dies). Maybe the new XBox GPU will emerge as the first appearance of that design principle.
