Clock for clock gtx 470 vs gtx 480

[MyLeftNut]

Anyone know any reviews showing clock for clock performance between the 2 cards at 1920x1200 resolution?

So you are looking for a comparison between a overclocked 470 and a stock 480? I have not seen one. But looking at all the reviews and numbers so far, I think it is safe to say the 480 will still beat it, but just by a smaller margin. My guess would be 3-4 FPS at that resolution. But still depends on the game.

I've been able to find 1 review (though an older one) that comes close to clock for clock gtx 470 @725 vs gtx 480 stock, and the 480 performance advantage ranged from ~15%all the way up to ~25% in certain cases at 1920x1200. Why such a large variation? Looking at the shader and texture processors of each, I don't see a 25% difference between the 2.

Thanks, from that last one, it seems to me that in most cases a 470 requires ~15% bump in core clocks to match a 480 in performance. So I'm assuming ~15% performance difference between the two clock for clock.
