No, its 1088 GB/sec. Check the Mark cerny Gamelab PS4 presentation.

And why what Mark said at PS4 presentation is in any way related to Wii U performance? Do you think that the implementation of eDRAM in PS4 if ever happened would have been the same as the one in Wii U? eDRAM was used in PS2, PSP, iPhone, Wii, 360.... And neither of those platforms had nearly close bandwidths as that. 

it's related because the combination of RAM + edram he mentioned is exactly what the wii u uses.

i don't know where you got the information that those consoles (except for 360) used edram. but they surely didn't have nearly as much RAM nor edram as wii u and certainly technology has evolved in the past 10+ years.

Also Wii U has very less DDR3 bandwidth which is sitting at 12.8GB/sec(revelead by teardown of Wii U and looking at the modules), so for countering this slow DDR3 nintendo should have to use High Speed EDRAM which also a reason for using this up to 1000 GB/sec(can be less). I just added a best case scenario for the bandwidth which is also based on the fact of the cerny.
