Intel CPUs are tied to specific Intel chipsets these days, with no third party vendors. AMD used to be much better (they have some small firmware for a support function that was signed, but even that was so half-hearted that one coreboot developer managed to recover the key - but didn't publish it). These days they support ARM Trust Zone (with an ARM processor), and that part of the system is all signed (as "Trust" doesn't mean that _you_ can trust it). It's Hollywood, essentially - can't have you crack your movie-playing device to copy their precious bits. And what else would anybody use a computer for, if not for watching blockbuster movies?
