Up to 4Gbits per chip, Wii U also has 2GBs ram, not 1.5GBs, remember the OS is taking up a locked out 512MBs worth of ram, but that is while it is debugging the OS, the OS will shrink to a less amount when debug has been completed, allowing for 1.7-1.8GBs of useable memory being likely for Wii U. Also this requires 8 chips with 2Gbit sizes, or 4 with the 4Gbit sizes, also allows for direct Wii emulation, as the GDDR3 is found in Wii.

PPC 470s includes the 476fp, it's part of that series, and it happened to come about in 2009.
This is what I mean about a 2009 console, Nintendo went out in 2009 to their hardware partners and started looking for cost effective hardware that would be state of the art (in terms of efficiency) at the time, they knew they were a few years out from release, so the technology would be withered properly at this time. A customized R700 gpu core with 2012 featureset (confirmed by antonz) with 6 476fps in pairs to give the impression of 3 cores with SMT. flipper including on the GPU and Wii's CPU features customized right onto Wii U's CPU would give 100% hardware bc without locking the system out, like GC wii BC works.
Just speculation on my part based on the CPU: "3 cores" 6 threads based on PPC476fp's running @ 1.8GHz modern features, but an embedded part.
GPU would look like this:
~600GFLOPs information I was given from a trusted source, but it would easily fit with 480shaders @ 600MHz giving you 576GFLOPs. Just some simple math based on early rumors and an inside source, but it's likely what the Wii U is hardware wise.
Nothing that will blow current gen away, at least without a ground up project that takes flipper's unique features such as lighting into account, but it also isn't completely thrashed by what is coming either. The rumors of those boxes are ~3X GPU wise what the Wii U is, but thanks to leaked specs from a week or two ago, we know it has compute units, tessellation, and even Arkam said that the Wii U's GPU was modern, just didn't have any teeth.
I'm sorry if I sound like a rerun or that I've posted this info half a dozen times, but I just think you guys feel that you'll have to endure another generation like this one, but EVERY tech person in this thread will tell you the difference in terms of architecture and power that Wii U will see when compared to other next gen consoles, is so much smaller that it's easier to compare Trinity to a HD7850, because that is pretty darn close to the same performance.
