Bad analogy. Dodge are omitting to put certain parts into their car, which genuinely saves them money. Intel are intentionally disabling parts of their die, which is fully capable of AVX.
It costs money to validate that those circuits on the chip correctly function at the target clockspeed, operating voltage, and TDP.
Intel saves money by binning these chips without validating the parts of them that they intend to disable/not support.
How would you describe AMD's habit of disabling cores and selling the chips for less? Of course AMD saves money when they do that because they don't have to spend money validating those other cores as being fully functional.
But the web is full of reports of people successfully unlocking cores on their AMD systems which would indicate that AMD was intentionally disabling them.
