‘Wii U eDRAM usage is comparable to the eDRAM in the XBOX360, but on Wii U you have enough eDRAM to use it for 1080p rendering."
That quote right there is the key piece of important information the rest is just fluff. This tells me that the speed of the eDRAM is about the same as it is on the 360 with the difference being the amount of eDRAM, 10MB to 32MB, had the Speed of the WiiU's eDRAM been significantly faster then he would of mentioned it in that very sentence as higher bandwidth is required for 1080p when all assessts remain the same.
Keep in mind that the 360 was designed for 720p forward rendering, which provided almost free x4MSAA at the time, also keep in mind that it was designed for a 2005 release, and back then just getting 10MB of eDRAM was friggin expensive, now the same eDRAM with the same bandwidth can be purchased relatively cheap with more capacity, just like how things are now with SSD's.
The key problem with the amount of eDRAM the 360 faced was that the industry moved towards deferred rendering which required a larger frame buffer, this resulted in Microsoft dropping the AA mandatory requirement, and then resulted in games, including halo 3, rending below 720p. The WiiU currently has enough eDRAM which shouldn't cause a problem, but then this is nothing to be surprised about as this should be the absolute minimum expected.
As I've said many times on this forum, the WiiU will be capable of some very nice graphics, just look at these last gen console to see the last of US and Halo 4 pushing each respective console, so the WiiU will have no issue in this regard, however, the PS4 and Xbox one will simply blow the WiiU out of the water in every aspect and this will be abundantly clear once we start seeing multiplat tittles on the PS4/Xbox one/WiiU.....if 3rd party bother with multiplat on the WiiU after this year...but that's a problem Nintendo has to fix and a separate topic altogether.
Anyways, that's my 2 cents, take it as you like.
