Also, you can't seriously think a wafer costs the same regardless of process? New processes are going to cost more per wafer as companies with high capitalization need to offset depreciation with higher revenues on new production lines. Given the amortization of these assets is going to be greatly accelerated due to the nature of the industry, older processes will be significantly cheaper than newer ones.
Yes, but even if both the GT200 and the RV770 are produced on the same process, the GT200 will be more expensive simply due to its increased transistor count (ie - die size). Less dies per wafer means higher cost per GPU. Larger dies also have a correspondingly higher chance of failure per core due to manufacturing defects which results in a lower overall yield. A lower yield also contributes to a higher cost per die.
rjc explained all this in his post. His figures were computed with both the RV770 and GT200 being constructed on the same 55nm process.

Result: Nvidia manages to sell $400 and $300 versions of G80 and posts record profits.
- You and others said the same about GT200, too big, too expensive, low yields, can't make a profit.
Result: Nvidia drops prices to $500 and $300 still manages to turn a profit in a down economy. Recently drops their GTX 260 prices even lower, closer to a $200 price point
I never said the GT200 was
too big,
too expensive,
can't make a profit. I did say it had low yields simply because that's what has been posted around the internet. Yes, it is big, yes it is expensive. Those two facts cannot be disputed. Especially not with nearly every GT200 review containing the word "monolithic".
Nvidia was definitely making a hefty profit on the GT200 back before the 48X0 was released. How could they not when they were charging $650 for a single GTX280 and $450 for a GTX260? These days, however, they've had to slash their prices so low that you can find the 280 for $410 ($375 after rebate). That's a $240 decrease in profit
per card that Nvidia is no longer receiving. I don't know how much profit Nvidia was expecting to make per card, but that lost $240 would have to represent a majority of it right there.

In the meantime, AMD still has not turned a profit since acquiring ATI. These are facts.
AMD may be in the red, but their graphics division (ie -ATI) is in the black.
