I'm pretty sure that the manufacturing costs to produce these chips are cheap too, and that's for both companies.
We can never know the real numbers of cards sold. But we can do some guesswork looking at smaller sample sizes. Like how the surveys are done.
For e.g a user 'Rangers' on beyond3d forum added up feedback reviews from newegg last week
GTX 690=45
GTX 680=541
GTX 670=786
Total=
1372
7970 GE=1
7970=569
7950=218
7870=158
7850=270
7770=240
7750=143
Total=
1599
With NV selling 1 elite card and 2 normal ones. Against AMD selling their whole lineup even with 3 months advantage in market.
Difference in totals seems quite small doesn't it? Which way will things head when both 660's n 650's launch.

Kepler cards are mid-rangers selling @ high end prices. It's pretty clear they have better margins.
Now this isn't measure of exact numbers. And So isn't the steam survey. But it's the closest we can come to guessing it.
