The base combinations for NVIDIA future GPUs now are 96 (1SM), 384 (1GPC), 768 (2GPC), 1536 (4GPC), 2304 CUDA cores/Stream Processors (6GPC). Given that we our sources are telling us the big monolithic die comes with 2304 SP, the question is what can be done with the memory controller. The logic dictates Kepler can come with the following memory controller configuration: 64-bit, 128-bit, 192-bit, 256-bit, 320-bit and 512-bit: to us, it is most logical that we see 64-bit low-end, 128-bit mainstream, 256-bit high-end and either 384-bit / 512-bit on the high-end compute side - and GeForce GTX 690, but this time as a single monolithic die, instead of typical mix'n'match of two high-end GPUs.
Continuing with the GK104 GPU, the chip has the same amount of fixed-function logic as competing Tahiti XT - 32 ROPs (Raster OPeration Units) and 128 TMUs (Texture Memory Units). As you can see in our architectural mockup, the decision to go with 256-bit memory controller results in 2GB GDDR5 and this is the only part where NVIDIA really loses to AMD: both 7950 and 7970 come with 3GB GDDR5 memory. True, the difference in planned price is estimated at $100 less for NVIDIA boards ($349-399 versus $449/7950 and $549/7970), which should mitigate the paper advantage of the HD 7900 Series.
