GTX 480: 600-625mhz
GTX 470: 600mhz

So the only difference between them is the bus width and 32 shaders? 32 shaders don't mean anything performance-wise. If it's the bus width that will distinguish the two cards, it means the 470 is bandwidth limited even at 600mhz which I don't think is possible.

I think 480's clocks have to be higher.
