content: Intel would NOT allow AMD to go out of business, because they'd be hit with anti-trust action, and probably forced to license x86 to a better positioned competitor. To your point about, NVidia is another story, but Intel is able to compete (they already outsell them in graphic controllers, technically), and some other guy like ARM, Qualcomm, or TSMC could buy up all of AMD's IP and start building graphics cards (probably better ones, too)
