Nvidia's next generation card, based on the chip codenamed GT200, will consume in excess of 200W, 250 to be precise.
Various sources have stated that the chip will be manufactured at 65nm, the same as current G9x chips. Nvidia usually doesn't risk to bring high-end chips with new a new process, preferring to deliver them manufactured in the process with which they have already some experience, common practice since the GeForce FX5800 fiasco.
The wattage claim seems valid since current G92 chips already feature 754 million transistors and consume around 100W. The GT200 card is rumored to surpass the one billion mark while aiming to bring more performance than the upcoming 9800GX2.
Considering that the 9800GX2 is expected to surpass 200W of power consumption, while delivering double the performance of an 8800GTS with 512MB, they look like reliable numbers. Nvidia's partner, TSMC, isn't pulling any 45nm high-K, low leakage, process out of it's "hat" in the next few months and this will be an high-end - to the extreme - graphics card.
The power consumption of the high-speed RAM set to be used will also play a role in these numbers.
A release date for the GT200 is rumored a few months after the 9800GX2, around June-July, possibly earlier.
More details should come around CeBIT, in early March.
