I was just about to post that, heh. I wonder, will this put to death the notion that only 10K Fermis exist period? At least, I hope it does on this board... It was simply illogical in the first place...
That could have been two misinterpretations of less than 10k cards at launch and less than 10k hotlots.
Perhaps that's it. Hmm, I recall having read some statements related to this on a certain vaguely tech-related blog:
So.. I guess that'd be 30.000 GTX480s and 470s, and between 170k and 370k GTX46x then huh
Do people still put credence in this ancient rumor? Look, if it had only been 10k hot lots, the supply of GF100's would have run out long ago. Instead, availability is, if anything, getting better, which is exactly what we expect from a normal ramp-up of production. If the yields were crap and nVidia couldn't make money off of the parts, there's no way in hell they would produce more of them. And yet, when I look at Newegg, I see ten GTX 480 producs, nine of which are in stock:

If NVidia can't sell any GF100s with 4 fully-active GPCs (i.e. yield on 512 ALU GF100's is ~0) there's prolly quite a steep yield curve.
I have a feeling that they're saving the handful of chips that work with all 512 cores active for a GTX 480 Ultra model or something.
I'm thinking refresh...GTX480 -> GTX485

That might be a bit difficult considering that the GTX 480 is barely PCI-E compliant, power-wise.
10k waffers ~ about 1 million of GPUs.
Peddie mentioned 400k GPUs shipped.
There are just two theories possible:
1. 400k GPUs were made out of the 10k waffers
2. 400k GPUs were made not only out of the 10k waffers
The first statement would indicate, that total yields are at least 40% (40% of 1 million = 400k GPUs). E.g. 6% for GTX480, 12% for GTX470 and 22% for GTX465 = 40% total = 400k GPUs. It means, that yields are (at least) quite acceptable, but the old risc waffers are still in use (contrary to your statement)
The second statement: risc waffers ran dry long time ago. It would mean, that risc waffers weren't enough to provide 400k working GPUs = yields are much worse then nVidia admits.
It is not possible to believe, that nVidia shipped 400k working GPUs and risc waffers ran dry long time ago and yields are good.
These statements contradict each other.
Because nVidia doesn't sell the cards to end users and they count the parts shipped.
If GPUs are being shipped to vendors, nvidia and AMD counts them as "shipped". Sometimes their marketing counts them even as sold (as long as they leave fabs, regardless if they are on the shelves or not).
If you want performance, why you pick single GTX480? Its slower than 5970, and as you say performance is everythingAfter that I plan to upgrade my rig like this:
i7 920 -> i7 980X
GTX285 -> GTX480
2x80GB RAID 0 -> X25-M SSD
Air cooling -> water cooling.
Performance being guideline here, not fluffy none-enthusiast concerns
DH found leaked specs on the GTX465. http://www.donanimhaber.com/DH_Ozel_Asus_GeForce_GTX_465_detaylandi-20097.htm
