Well, AMD will be making the chips in the next XBox, the next Playstation, and the graphics for the next Wii so that's something at least.

I don't see Apple switching to AMD, the performances and efficiency just aren't there.

It's kind of confusing because technically GlobalFoundries is separate from AMD. So if Apple wanted to manufacture their own custom ARM chip, would they be talking to GF, AMD, or both?

I also wonder what role AMD proper (as opposed to GF) will have in some kind of theoretical future world where ARM provides all the chip designs. Wasn't architecture sort of their main thing previously? I know a lot of companies add their own little things on to the base ARM designs, but it still seems like AMD will have to scale back their design team considerably in such a scenario.
