I've never claimed, nor has anyone, to my knowledge, that Intel: 1) doesn't "bin", and 2) has a "separate die", for "every SKU". Nice strawman, though, it really brought out the hardcore Intel fans.
Binning is different than harvesting.
Binning, is where they take either a 2-core or a 4-core die, and test it (Shmoo plots FTW!), and then mark it, and sell it at certain speed grades. They may also disable features in the lower speed grades.
Harvesting, is where they take entire cores, and disable them, and sell them as a separate product. For example, a 4-core die, with one or two bad cores, being packaged and sold alongside (*intermingled with) 2-core dies, FOR THE SAME SKU. It is THIS that the Intel fans on this board, have previously EXPLICITLY DENIED HAPPENS.
But we know, from the linked AT article in the OP, that THEY DO.
