The perennial favorite thin and light is on the way, featuring the company’s new M1 chip — it’s first desktop CPU built in-house. The system looks to be largely identical to the last several generations of Air, with most of the big changes happening under the hood. > Per Apple’s numbers, the system should be 3.5x faster than earlier models and faster than 98% of the PC laptops sold in the last year. Even more notable, the new ARM-based chip means it can operate without a fan. The company has long claimed that battery efficiency is one of the biggest benefits to its new chip, and that certainly seems to be came here, with a claimed 15 hours of web browsing and 18 hours of video playback on a charge. Huge if true, and a big bump from the 12 hour claims for earlier models.
