"Come Broadwell and destroy AMD, so ATI can be ATI again and no more AMD."
If i'm not much mistaken, ATi is AMD, so to make AMD fail would be to make Ati fail, and both would cease to be. In the case AMD pulled out of the CPU market they would still be AMD making ATi cards, and all notebooks would be stuck with crappy intel graphics.
Lastly, if i'm not much mistaken, intel and amd cross license instruction sets, specifically the x86 to AMD, and the x64 to intel. If AMD closed, it's likely your intel chip might mean next to nothing when they're forced to discontinue x64 instruction sets in their next line of CPU's until they create their own (If they can do so without infringing on AMD's design), as it isn't likely AMD would sell them.
