Intel has been doing this for years with 100% flawless chips. Crippling a chip is part of their business. Their yield management is fantastic such that they run entire wafers at the higher spec then choose what % to sell as lower-end SKUs purely based on demand. Perhaps 10 years ago this was driven by yield quality, but nowadays the number of chips out of a batch that can't pass the test for the top-of-the-line product in that batch are < 1%.
