Does the WiiU have memory dedicated to the GPU? Or is the 2GB for CPU OS and GPU?

i think the eDram quantity was stated by IBM an his webpage
they said it tripled the eDram used until now, probably 32MB

the WiiU has a GPGPU instead of a separate CPU, GPU, so the 1GB of main RAM will be used for CPU functions and GPU functions, by the GPGPU, which is a GPU acting as a CPU and a GPU at the same time......got it?

the remaining 1GB its still a mystery

Saying it is a GPGPU doesn't mean that it is an APU ... more likely it means that the GPU is based on a modern architecture that has demonstrated support for (something like) CUDA.

 

I would suspect that the 2GB total memory is shared by the CPU and GPU but that both processors would have embedded memory and on the CPU that would act as a L3 cache and memory on the GPU would represent the screen buffers and a texture cache. As a guess I would say that the CPU probably has 16MB to 32MB of embedded memory while the GPU has 32MB to 64MB of embedded memory.

I'm guessing closer to 12 MB to 16 MB on the CPU depending on the number of cores (3 or 4).
