INT12 is 3 or 4 times faster than FP16 on a NV3x, depending on the operation
No, INT12 has twice the execution units, apparently. I still think more tests need to be done (the total number of execution units just doesn't add up...). By combining floating-point ops and integer ops, then, maximum performance can be achieved.

Just like with CPU's, I see no reason to believe that integer operations are pointless in a GPU.
