I won't think Apple would want to use AMD CPUs instead of Intels as they have learned the hard lesson: "if you can't beat them, join them" (regarding CPUs)
Apple turned to Intel because they are the biggest CPU maker and simply is the safest bet.
But Apple could buy AMD and use their own Apple branded CPUs in coming Macs and / or iOS devices.
