Re: OTOH there is the case
Everyone was hoping the extra dies in Threadripper were deactivated chips, so they could get free CPUs. But it is a case of "impossible" here, as they are empty silicone.
But the good old days, I did get a free core from a Phenny II x3, and there was a free bit or two to add to the pixel shaders for the ATI cards if you had a pencil. :)
