The Fermi Thread - Part 3

They are definitely more expensive, but don't forget, that they are salvage parts, so the yields are better. More memory, but slower afaik, that can also make a difference. And lastly, they don't have the same contract as ATI with TSMC. They are producing more chips, so they can have much better deal.

Depends on the salvage part...
Correct with the TSMC contract, we don't know anything about either contracts, though I suspect AMD/ATi has been getting a decent discount as well over the last few years.
I also highly doubt Nvidia is seeing 60% yields right now...

Die in between 280 & 285 dies = similar cost to last gen assuming die size alone is the sole factor
PCB less complex than their previous 285 with smaller memory bus
Lower binned ddr5 offsets costs of larger bus

I say we can all armchair build a full product and assume manufacturing costs its not so hard....

40nm wafers are more expensive than 65/55nm wafers...
Lower binned GDDR5? It is clocked slower but I don't think it is a lower bin.
