No, they are not connected electrically. CPU VRM is like a separate PCB when you talk about motherboard voltage delivery. The CPU VRM only has a connection to the 4/8pin socket. If this were not true, multiple powersupply rails would be useless as you would be shorting them together in the board.

A GPU on the other hand is built around sourcing power from multiple inputs. With specific sections of the regulation circuit being connected to specific inputs.

HP-UX. I came, I saw, I was sad it would not run on my X86 box.
