According to a rumor from Apple supply chain workers, the smallest laptop in the MacBook family, the 12-inch MacBook, will return this year with Apple’s brand new ARM-based chip. It makes sense that the 12-inch MacBook is the first of its kind as it is powered by Intel’s Core Y-series chips with low power consumption.
Ming-Chi Kuo previously said that either the 13- or 24-inch iMacs will be the first Macs to feature Apple’s in-house chips. Allegedly, the new report comes directly from TSMC, the only vendor of Apple A-series chipsets from Apple. It is said that the foundry has stopped manufacturing chips for Huawei and can now easily meet Apple̵
The source adds that the upcoming A14 Bionic chip, used in the iPhone 12 family and also implemented as the A14X Bionic in iPads, will make it into this year’s 12-inch MacBook as well. That said, the A14X bionic silicon will also power the MacBook.
This would greatly improve the MacBook’s performance, but more importantly, it would offer great battery life. Apple promises something on the order of 15 to 20 hours on a single charge.
Note that this will be the first MacBook to make the transition, and that the rest of the MacBook line-up – the 13-inch, 15-inch, and 16-inch MacBook – will have their CPUs versus ARM for the next two years -based exchange will.
