AMD and GlobalFoundaries have renegotiated a silicon supply deal which should see AMD switching to a per-die payment method for any chips produced on GlobalFoundaries new 32nm-based manufacturing process. The renegotiated deal replaces the previous method of payment which was based on a per-wafer deal.

In a press statement, AMD said that from now on it's "price for 32nm products will be based on a good die", which implies that AMD was previously seeing too many duff dies per 32nm wafer for its liking and therefore only wants to pay for working chips, which is fair enough.

As an incentive, AMD has offered to pay a quarterly sum to GlobalFoundaries next year, on the condition that they meet "specified conditions related to continued availability of 32nm capacity" at the beginning of the year.
