Report: Apple Silicon iMac with custom GPU will launch in the second half of 2021



Apple will debut a powerful custom graphics processor in its first Arm-based iMac, due to launch in the second half of next year, according to a new report today.


Codenamed “Lifuka”, the self-developed GPU to be used in Apple Silicon-powered ‌iMac‌ will be manufactured with a 5-nanometer TSMC manufacturing process and will offer better performance and be more energy efficient than the Intel processor. , which replaces, according to the Chinese -language newspaper The China Times.

In the past, Apple introduced Mac PCs with Intel processors equipped with Nvidia or AMD GPUs, but insiders said Apple had canceled support for AMD processors on the 64-bit macOS Arm operating system, indicating that Apple would be accepted. in the future. Silicon Mac PCs can use a graphics processor developed and designed by Apple. The industry recently announced that in addition to the Apple Silicon processors, Apple’s launchediMac desktops released next year will be equipped with Apple’s self-developed and designed GPUs.

According to relevant sources, Apple’s self-developed graphics processor is progressing smoothly. The code for research and development is Lifuka. Like the upcoming A14X processor, it is manufactured on a 5nm process by TSMC. Apple has designed a series of processors for Macs. The new graphics processor will provide better watt performance and higher computing performance. It features tile-based delayed rendering technology, which allows application developers to write more powerful professional application and game software.


Apple announced at its WWDC developer conference in June that over the next two years, Macs will move from Intel x86-based processors to its own Arm-developed Apple Silicon processors. Bloomberg said Apple is currently developing at least three Mac processors based on the 5-nanometer A14 chip, which will be used in upcoming iPhone 12 models.

Apple analyst Ming-Chi Kuo predicts that the first Mac models to accept Arm-based chips will be the 13.3-inch MacBook Pro and ‌iMac‌ with a redesigned form factor, with Apple planning to release new models in the fourth quarter of 2020 or 2021 at the earliest. Before launching its Arm-based ‌‌iMac‌‌, Apple is expected to upgrade the existing Intel ‌‌iMac‌‌.

Contrary to Kuo’s prediction, today’s report claims that the first Arm-based Mac will be a super-lightweight 12-inch MacBook, codenamed “Tonga”, which will be released by the end of 2020. In addition, the report says the A14 chip for a feature in Apple’s upcoming iPhone 12 range is codenamed “Sicilian.”
