The new GF104 has eight Streaming multiprocessors (SM) while the old GF104 had seven. This could very easily be the same GF104 chip with one streaming multiprocessor disabled, as Nvidia simply didnt need that more power back in July time when it launched Geforce GTX 460 cards. Now, since they might need some more power, they simply enabled the eight SM unit.
if they do come out with an unlocked gf 104 then you should be able to flash the bios of a gtx 460 1gb to a gtx 475. Unfortunately, you could also brick your card doing that so make sure that you know how to blind flash if you do. Hmmm, I wonder if you could potentially flash a 768mb card...
Nvidia might up the memory to 1.5gb with gtx475 though, which would prevent a bios change. I don't think they will, though, because they need to move quickly and existing gtx460 boards as is should be compatible with the a 384 shader gf104, so no manufacturing changes or updates would need to be made.
Have there ever been any fully enabled GF100 cards releases yet?
GF108 is fully enabled and GF106 is fully enabled as far as shaders/cores. It does have 1 64bit memory controller disabled I believe though.
GT 430 is the only Fermi card that has nothing disabled.
Being GF104 (assuming that is correct), I wonder if the 475 label will mean that it will really be faster than a 470. I would think Nvidia would be happier selling the much smaller GF104 for equal or better performance.

that makes sense, but if they do call it a 475, its most likely going to perform better than a 470
How could they up the memory to 1.5GB? GF104 only has a 256-bit memory controller, doesn't it? The 768MB GTX460 has 192-bit. They would have to make a 384 shader, 192-bit memory bus card to have 1.5GB. And it would lose ROPs etc as well (IIRC).
1GB and 2GB is what we should see.
Not if the 460 and 465 are any indication.
