AMD is killing Intel on the CPU front. To the point you have to wonder when Apple might start putting AMD inside..
Both AMD and Intel are selling every CPU they can make. Unfortunately for AMD, just like in previous periods when they had a technical advantage, they can't make enough to displace Intel. Apple won't risk its special treatment by Intel for leftover scraps of already insufficient manufacturing capacity from AMD.
Maybe this will change, but for now AMD has a technical advantage they can't exploit.
