The problem Nemesis is it's only 128mb (has this even been confirmed?). There is no way that is going to hold up at 1080p with AA. Should be about good enough for 1080p without AA however, which in itself is nothing to be sneezed at.
Intel never told us benchmarks or performance gains for edram chips.They only talked about gains without edram . They did however show edram chips running on 2 differant occasions. As I said Intels is being very hush hush/ With edram it would be easy to expect 2x improvement over HD4000. Like on a ulv with GT3. expect only 30% gains . That sounds reasonable. Until you strap 125mb of edram on the package threw a wide buse. If we know what the bandwidth is which some have figured . Than the performance should be easy to guess.GDDR5@4000ghz. Than the most important thing the gain from being on package
I have no doubt that edram can enable higher performance, but what you're missing from the picture is TDP. Edram will not double or triple performance per Watt, I would even question if that improves at all with on-chip Ram as an additional power draw. So the increase in performance will probably be limited regardless of edram.Intel never told us benchmarks or performance gains for edram chips.They only talked about gains without edram .

The way Intel talks about a lot of their products, I think it is very difficult to extrapolate what the likely performance gains of GT3e will be over the HD4000.
Are they comparing to the desktop version or a mobile version of the HD4000?

The Xbox uses its edram for some nifty tricks with Xenos, improving the utilization as far as I know. The edram isn't there to improve power draw but to improve the shortcomings of the chip itself. Haswell might profit from a similar approach, but I don't think it's such a clear cut.Well I just going to assume having edram on package offers advantage of substance, I really haven't seen it done befor other than xbox version.
The GT3 at 55 watts is 4core with GT3e or without edram.
