One of the more interesting stories about Apple in the past couple of years has been about its chips. In 2010, Apple announced its first iPad was going to be powered by a chip called the A4, designed by the company's teams specifically for its devices. Back then, the iPhone was doing well, but its chip ambitions were unproven.
Fast forward to today, and not only is the iPhone one of the most popular consumer products in the world, but it's also powered by the successor A-series chip. Apple's also used that technology in its other devices, including the Apple Watch, AirPods, Apple TV and HomePod.
Over the past couple of years, Apple's also begun using a variant of its A-series chips in its computers, starting with the M1 in 2020. Apple said it would take two years to transition its product line of computers over to the M-series chips, with rumors swirling that the company will likely finish in the summer with a new Mac Pro.
During today's event, we may hear more about the M1 -- or even its higher-performance cousins the M1 Pro and M1 Max. The Mac Mini, which helped kick off the M1 transition two years ago, is now due for an upgrade. And so is the MacBook Air. Meanwhile, there's already talk about an M2 chip on the horizon.
