The only difference is temporary registers who can be either FP16 or FP32, and register usage is very important on the NV3x ( the least, the better )
Thats the point I was trying to make. By sticking to one simple paths things are easier....meaning less transistors and easier optiomizations (remember jc said that scheduling for the NV30 was tricky). I am not saying either is better. Just saying that wiht every engineering choice is a trade offs. they both have "good" and "bad" parts...
