Apple will announce Macs are shifting from Intel chips to its own, ARM-based, processors at WWDC 2020 later this month. While the timing of the announcement could change, Apple is aiming to give developers time to adjust prior to new Macs being launched in 2021 (via Bloomberg News).
Macs With Arm-Based Processors Set to Arrive Next Year
The new chips will be based on the A14 processors set to be used in the next generation of iPhones and iPads. The project that is working on the shift has reportedly been given the codename Kalamata. It is understood that that tests conducted by Apple have show ARM-based chips yield significant improvements over those from Intel. Improvements are said to be particularly noticeable in graphic performance and AI. The arm processors are also more power-efficient, so we could see thinner and lighter Macs.
If confirmed the shift will be the first time in 36 years of the Mac that the devices will not include third-party manufactured processors. The digital-only WWDC 2020 starts on June 22.
