Although this topic has been discussed for a couple of years, it seems that this year will be the year that Apple presents its computers with its own ARM processors and stops using Intel's.

According to information from Bloomberg, Apple would be preparing 3 new ARM processors for its computers (project codename 'Kalamata'), which would allow them to be faster and lighter and have more interaction with other Apple devices.

Presentation

The presentation of this new project would take place on June 22 at WWDC20 (an online event due to the actual pandemic). This move appears to be related to the performance and efficiency issues of the latest Intel processors. In this way, by incorporating its own processors, it would allow Apple not to depend on third parties for the development of their computers.
This, in addition, will allow you to advance in areas such as Artificial Intelligence (AI) or Augmented Reality (AR), as it has already shown in some of its other devices.

New Architecture

It seems that all 3 new processors are based on the A14 chip (expected to be used in this year's new iPhone). One of these chips would have a 5nm architecture a 12-code CPU (eight high-performance 'Firestorm' cores and at least four energy-efficient 'Icestorm' cores).

And the software?

This is a very important change in Apple's hardware, which will also affect the development of the operating system. But what about other developers' software? How will the change of processor affect them? We will have to wait for the more than possible presentation of these new processors at WWDC20 and the possible instructions to the developers.

Summary

As a summary of what Bloomberg reports:

• There are 3 Mac System-on-Chip (SoC) in development.
• These chips would have a a 5nm architecture and be manufactured by TSMC.
  The first of these chips will have 12 cores (8 high-performance and at least 4 energy-efficient cores).
  The SoC will also include a GPU.
  Mac computers based on ARM still run macOS rather than change to iOS.
  First ARM computers would be lower-powered MacBooks.
