The GF104 should have 384 SPs organized as 16 clusters of 24 SPs. The leaked screenshot that Expreview.com managed to grab showed the GTX 460 with 336 SPs/CUDA Cores which means that it has 2 disabled cluster which leaves it at 336 SP. The full GF104 has a 256-bit memory interface, but with one MC block disabled you get the 192-bit memory interface seen on the leaked specs list for the GTX 460.
...
This sounds a lot like the G92 which had full 128 SPs but as you remember the first card, the 8800GT had only 112 SPs, and according to our sources, there has been some talk about the possible GTX 475 based on fully enabled GF104.
NVIDIA also prepping GF104-based GeForce GTX 475?
