Rumors of ARM-based Macs continue to appear. Lower power and longer battery life are always cited. But even more important are the business advantages Apple would reap from switching from Intel to ARM. Former Apple engineer David Shayer explains what would be behind such a processor transition.

After years of rumors about how Apple was planning to transition the Mac from Intel-based CPUs to its own ARM-based processors, Bloomberg reports that the move will start in 2021.

Apple seemingly squeezed Intel into an impossible position by negotiating for a purchase while working on a settlement with Qualcomm. Now Apple has control over a current steady supply of 5G smartphone chips and a path to make its own for future iPhones.

For decades, Intel was the undisputed king of chips for desktops and laptops, but in just a few short years, Apple's A-series chips have almost caught up to Intel in performance. The Motley Fool’s Ashraf Eassa explains why.

Over at Fast Company, Andy Ihnatko ponders what might happen if Apple were to develop its own CPUs for Macs, replacing the Intel chips that have powered Macs starting in 2006.
