Each microprocessor is graded in the factory Yes Intel does binning but that is to classify processor classes. Intel runs their E3, i7, i5, and i3 production on the same die. It looks like this: Memory controller went bad and can't handle ECC? Looks like an that E3-1??? vX just became an i7-X???. Virtualization went bad? That i7-X??? just became an i5-X??? Bad 1/2 cores? Well that i5-X??? just became an i3-X??? There is additional binning but that just determines if the processor can have an unlocked multiplier or not.
