I suppose this is also used for yield quality? For instance, AMD is known to sell the same actually-8-core chip as a 6-core if the transistor yield was poorer.

I believe this is a standard in the industry, right? You can theoretically unlock these cores yourself, but there's a decent chance it will break or cause other significant problems.
