An A14X processor codenamed "Tonga" produced by TSMC with ARM architecture, less than a kilogram of weight and a battery capable of ensuring an autonomy between 15 and 20 hours should be the main features that will accompany the return to great style of the "small" MacBook 12 from Apple.
According to indiscretions of industrial sources reported by the newspaper The China Times, it would be the MacBook with 12-inch Retina display, which came out of the list last year, the one chosen to start the two-year transition from Intel processors to those developed and designed directly by the Cupertino company.
Bloomberg said Apple is currently developing at least three Mac processors based on the 5-nanometer A14 chip that will be used in upcoming iPhone 12 models. The A14X chip will be mass-produced by TSMC later this year and will also be used in New generation iPad Pro.
Apple's first Mac processors will have 12 cores, including eight high-performance and four energy-efficient. Apple would also be exploring the possibility of making processors with more than 12 cores in the future and it seems that it is already working on the second generation based on the A15 chip.
This isn't the first time rumors have circulated about choosing a revamped 12-inch MacBook for Apple Silicon's debut. Rumors to this effect had already emerged last June. Design changes should be minimal and there may even be 5G connectivity built in.
In contrast to what emerged today, analyst Ming-Chi Kuo said last March that the first MacBook with an Apple processor would be the 13.3-inch Pro expected between late 2020 and early 2021. Kuo it has however also planned a MacBook Air in the same quarter or in the first quarter of next year. It would not be excluded that this could be the 12-inch MacBook.
Today's report also states that Apple will launch an iMac with Apple Silicon next year that will integrate a powerful custom graphics processing unit as a replacement for AMD's GPUs that the Cupertino company has traditionally relied on. Furthermore, the documentation reports that the A14 chip present in the next range of iPhone 12 has the code name "Sicilian".
