Yeaaaa, that's why a 256mm^2 chip beats yours. ROFLMAO @ Nvidia you mean? Quantity = quality @ AMD camp? Nvidia HAS A HUUUGGEE CHIP. 572mm^2!!!. But anyway, the companies use different arcitectures. And both companies have different strategies. AMD = multiple midrange gpus on 1 PCB for high-end, Nvidia = Monolithical chip to beat the rest > works, but with a chip this size, the yields may suffer = high prices/costs. As for AMD, they use a much smaller chip. They can get many chips from a wafer with reasonable yields. Edit: The extra shaders is obviously a backup = better yields. AMD/ATi is smart enough NOT TO release a card with those unlocked shaders. That would be pointless right? Because the increase would be minimal. We saw the same thing happen @ Nvidia a while back. After 8800 GTX > 8800 GTS!?(almost Faster than GTX) But then !!! 9800 GTX! = Overclocked 8800 GTS. Wierd right!?
