Indeed, AMD's current selection of chips seems to be significantly less energy efficient than Intel's, so the speculation about notebook chips strikes me as extremely odd. Things are a little different at the high end - I think an Opteron-based Mac Pro might be realistic. The new 12-core Opterons are more energy efficient than the latest 8-core Xeons, and roughly equally fast. But then, if the top brass are negotiating now, real products are probably at least a year away, if not more, so who knows.
