Can't have your cake and eat it too....

7800GTX-512 had higher clocks on the same process and ran hotter
7900GTX had higher clocks on a smaller process and ran cooler

Neither had an increase in any type of unit over the original 7800GTX-256.

Expecting a 8900GTX on the same 65nm process as G92 with both higher clocks and higher unit counts is a bit optimistic. G92 wasn't exactly sipping power.

Still, it looks like Nvidia came in 100Mhz shy of its target shader clock...1400Mhz would have taken them to the 1 Teraflop finish line.
