> Sure, but how are they going to produce iPads and iPhones before then? They can't have more than a year's worth of CPUs stockpiled.

From TSMC chips. Basically if TSMC insists on raising prices to levels above what Apple is prepared to pay they can threaten to move away from TSMC eventually. If TSMC refuses to budge then Apple will have to pay the higher prices in the short to medium term and then expend capital to not be beholden to TSMC over the long term. So then the question is does TSMC value the relationship over the long term or do they value the higher prices in the short to medium term? That could be Apple's negotiating position.
