Even if the blended C2D yield was 80% (it wasn't) there would have been at least 12 million defective C2Ds available for recovery into at least 10 million single core parts. A sizable number of those duds will be unidentifiable in a production environment, even if potentially recoverable. How exactly do you know where the failure is when you have maybe a couple hundred milliseconds to figure it out? Others will be totally dead. Some of the remaining may pose reliability concerns if no long term reliability studies have been conducted on those defect modes. Recovering would be problematical and add complexity to the production flow that doesn't make sense for a very high volume environment. Die cost is not the major factor here.
