Apple news website Mac Rumors reported that Apple continues to plan to break up with Intel and use its own Arm architecture chips in Mac, and this plan is expected to come true in 2020.
"Mac Rumors" quoted sources as saying that Apple is carrying out a project code-named "Kalamata". Simply put, the plan is to abandon Intel processors in its own Mac computers and use all Arm architecture chips developed by itself, so that it will not be constrained by Intel.
Currently, the processors used in Apple's Mac series products all rely on Intel. However, Apple is planning to convert the processors of its Mac series products to its own chips based on the Arm architecture, just like the iPhone A series chips.
Currently, all of Apple's Mac products use Intel's x86 chips, while iPhones and iPads use Arm architecture chips. Intel x86 chips and Arm chips use different instruction architectures.
Intel's chips are complex instruction set architecture (CISC), while Arm's chips are reduced instruction set architecture (RISC). RISC instructions are actually smaller and simpler than CISC instructions, which means that Arm processors require less power and are more efficient in performing tasks.
But Arm chips are not as powerful because x86 chips are designed for higher-end desktops, while Arm chips are designed for low-power applications such as mobile devices. Arm has always focused on battery efficiency, while Intel focuses on maximizing performance.
Since the emergence of the PowerPC processor in 2006, Apple's Mac series has continued to use Intel chips. However, as a result, Apple has been constrained by uncertainties such as the release schedule and delays of Intel chip products.
In the past few years, Intel has experienced several chip delays, which have affected Apple's product plans. Therefore, Apple believes that if it uses chips developed in-house, it will allow Apple to release updates on its own schedule and make more frequent technological improvements.
In addition, Apple can also use chips designed by its own internal team to differentiate different products and integrate hardware and software.
Apple's A-series chips for iPhones and iPads all use the Arm architecture, and every year these chips developed by Apple itself become faster and more efficient.
When Apple released its latest A12 and A13 chips, it emphasized that these chips are faster than Intel chips in competing devices.
Mac Rumors points out that the MacBook Pro, MacBook Air, iMac Pro, Mac mini and the upcoming Mac Pro will all be equipped with Arm-based processors in the form of T1 and T2 chips to power the Touch Bar and other features of these devices.
The T2 chip integrates multiple components, including a system management controller, image signal processor, SSD controller, and Secure Enclave encryption device, and can also power the Touch Bar and Touch ID.
Bringing Arm architecture chips to Mac can improve efficiency and battery life without sacrificing speed, and Apple can also reduce the size of certain internal components, thereby developing thinner devices.
Apple's goal is to transition to its own Arm architecture chips starting in 2020, and this transition period may still take some time.
