There's something that people aren't paying enough attention to, and it's revealed by the above image and this one here:
What am I talking about? Look back at the RV770 chip for a moment. The centre of the chip has all of the main GPU stuff, and then there's some stuff around the edges, most of which is easily identified.
Now look at the Wii U's chip. Yes, there's the eDRAM, etc, on the left. And they've identified a heap of things on the right... but the odd part is all of the unmarked area. About a quarter of the entire chip is entirely unaccounted for, including a huge gap near the centre. There are visible details, so we can be fairly confident that it's not just empty space. So what is it? What hasn't been identified, and what impact does it have on the system?
I don't suppose anyone knows if there's an equivalent die image for the Wii's GPU, for comparison?
