I think the real advantage of Apple so far is to have the kind of volumes and margins with iphones to be able to have privilegied access to TSMC fabs and processes, and therefore now it will automatically trickle down on Macs and their new SoCs granting them a head start on everybody else, even irrespective of any other kind of possible architectural advantage or design decision.
