Rumors of Apple (AAPL -2.88%) exploring ARM-based Macs have persisted for years, with a recent report from MacBidouille renewing speculation. Apple allegedly has iMac, Mac Mini, and MacBook prototypes running off of its own A-chips. Talk of Apple using its own chips has been around since at least 2011, but a lot has changed since then. Specifically, Apple has taken its chip prowess to unprecedented levels in terms of sophisticated designs as well as raw performance.

Apple's chip capabilities have skyrocketed in recent years, thanks in part to moving to custom designs. That's a potential threat to Intel (INTC -3.79%), who would be displaced as the current Mac processor vendor. Intel likely has plenty of time before it has to start worrying though, as any transition would take many years to materialize, if at all. Even then, Intel has been working aggressively to win Apple's foundry business so it could make up for lost chip revenue with foundry revenue.
