no the reason is: they make a specific batch of the processors, making it a large batch so that they can tune one of the wafer manufacturing machines over a period of several months to get it up to as close to a 100% yield as they can, then stockpile them.
Wasn't the power processor used in Sony's playstations a while back, with something like five or six CPUs and some other thing to coordinate them? I heard they got around the yield problem by making them all with extra processors so they could make a subset of them that happened to work available in the actual delivered machine.
