Our developer friends called it brute force chip, with not so much brains.
Putting 240 Shader units in the chip that basically remains on G80 and G92 design will naturally get things moving faster. More Shader units at faster clocks will always make your card faster, especially at higher resolutions.
G92 with 65nm design has 128 Shaders, while GT200 has 240, or almost twice as much. The die size of GT200 is much bigger than G92 and that is how you get the fastest chip around.
Our developer friends added that the last innovation that Nvidia did was G80 and that G92 is simply a die shrink of the same idea. You can look at GT200 as G92 with 240 Shaders.
This results in GT200 running quite hot, but it will compensate with sheer power, so let’s just hope that Nvidia's yields of such a huge chip (rumoured bigger than 550mm2) will be acceptable.
