Well now, 3DCenter compiled a few specifications of the GK104 and GK100. Take it witha grain of salt, they go like this:
GK104
- 640 to 768 CUDA cores
- 80 to 96 TMUs (depending on what the CUDA core count ends up being)
- 384-bit GDDR5 memory interface, 48 ROPs
- Built on the 28 nm TSMC process
- Products based on this will launch in the first quarter of 2012
- 1024 CUDA cores
- 128 TMUs
- 512-bit GDDR5 memory interface, 64 ROPs
Um yeah, that's all folks :)
