Bloomberg talked about the new Mac with ARM processors, which will be released in 2021. Apple is developing three variants of the 5-nanometer SoC A14, including a 12-core model


We have already written more than once about Apple switching to its own ARM processors in Mac computers instead of Intel CPUs, which have been used since 2006 in mobile and desktop models. There were so many relevant pickups that it was perceived as an already confirmed fact. Just last month, a recognized analyst, Min-Chi Kuo, argued that it was planned to release several new Macs with ARM processors in laptop and desktop form factors in 2021. Now, the Bloomberg publication, citing people familiar with the situation, confirms this data.

Presumably, Apple is developing three Mac processors as part of the Kalamata project and all of them are based on the Apple A14 SoC, designed for the iPhone 2020 line. According to Bloomberg, the first of these chips will be built on a dual-cluster scheme with eight high-performance Firestorm cores and at least four energy-efficient Icestorm kernels.


Earlier, we heard that the transition to ARM processors will significantly increase the competitive advantage of the Mac line, as well as reduce dependence on Intel, while reducing processor costs by 40-60%.

Bloomberg provides some technical details about the processors themselves:

In total, there are three SoCs related to the A14 chip for the iPhone 2020 line; work has also begun on a single-chip Mac system based on the SoC A15 (tentative name), which will be used on the iPhone 2021. Allegedly, Apple decided to adhere to one development cycle for smartphone and laptop SoC. Future SoCs designed for Mac computers will be released according to the 5 nm process technology at TSMC capacities. The first-born will receive a 12-core CPU: eight high-performance processor cores and at least four energy-saving cores. In comparison, the SoC A12Z used in the latest iPad Pro has eight processor cores: four high-performance and four energy-efficient. In addition to the central processor, the SoC will also include an integrated graphics processor. Mac computers with ARM processors will not switch to iOS, but will continue to use the macOS desktop OS similarly to how Always Connected PC class laptops on ARM processors use Windows 10. High-performance MacBook laptops will become the first Apple computers based on ARM chips of their own design (probably , Air), since it is not yet possible to achieve the same level of performance as the x86-compatible Intel models used in the MacBook Pro, iMac and Mac Pro. Back in 2018, Apple developed a prototype SoC for a Mac based on the A12X Bionic SoC. It is believed that the results so pleased Apple that it did not hesitate to decide on the transition to ARM chips in 2020.

Mindful of the far from successful Microsoft experience, which to this day has not provided full support for x86 applications in Windows 10 on ARM, the biggest question is how much Apple will succeed in this matter. Here you can also recall the Marzipan project, which provides for the gradual merger of iOS and macOS. It was previously reported that in 2021, Apple will give developers the opportunity to combine applications for the iPhone, iPad and Mac into a single application. In addition, as we noted earlier, Apple has a better chance of successfully implementing the concept than Microsoft, given the close integration of hardware and software components.

The announcement of the first Mac models on ARM processors, which should mark a new chapter in the history of the line, is expected next year at the WWDC 2021 conference.
