Moore's Law allows later and more sophisticated processors to compete in price with earlier ones. But a separate factor is the "learning curve". The same chip built in the same old process node will get cheaper over time as production grows. The fixed costs will have been amortized, the per wafer yield will tend to go up and so on. That allows a processor initially sold for $300 to be sold for less than $10 five years later.
