NVIDIA GeForce GT200 is 65nm or 55nm
 

From what we know, Nvidia has placed orders for 65nm and 55nm versions of the GT200 chip and there is a big reason why. Nvidia is simply playing it safe and it doesn’t want any delays.

Nvidia traditionally migrates from bigger transistors to smaller in the entry-level, less complicated chips and then tries this in the higher end. Usually this works well, and you can remember that Nvidia went from 80nm to 65nm in this order.

As it’s pressured by time it will try to make even its biggest chip in 55nm. If it fails, it will have a 65 nm version of the chip ready to take its place. 55nm means that the chips will run a bit cooler and that you can crack the clocks a bit higher and we will probably learn if the fastest version of GT200 will end up at 55nm.
