Potentially, changing one processor platform to another, in this case – from Intel to ARM architecture – is an unpredictably lengthy process that includes both technological and financial and marketing aspects of the company’s activities.


Of course, the main question is why is this transition happening? Why is Apple switching to ARM, especially its own production?


The new name of Apple’s ARM processors is “Apple Silicon”. This, as well as the fact of avoiding the use of processors from Intel, was announced at WWDC 2020. The transition is planned to be implemented gradually, over 2 years.


The decision to change the processor platform was officially made to strengthen the position of autonomy and management of the bundle of hardware and software platforms of Apple, and to improve overall performance.


However, there are alternative versions. In particular, there is an opinion of some former Intel employees about problems with the quality of the Skylake family of chips.

Historically, this will be the third generation of processors used by the Apple platform.

In all cases, the motive for the transition was the principle of increasing the autonomy and performance of the architecture (that is, Motorola 68000, then PowerPC, and finally Intel).

ARM Holdings is the name of a UK company that develops processors and other electronic components.

ARM issues licenses for its products – that is, other companies can purchase a license to create their own chips on this architecture, create processors to implement the list of arm commands.

At this time, the processors used by Apple are the leaders in performance – both in mobile phones and tablets, clearly the best in their segments in this regard. An important aspect is also the control over the combination of hardware and software.

Also, however, the performance of ARM processors that are supposed to be installed in Apple computers is clearly much lower than those currently used, and the autonomy is significantly higher.


In addition, there are other difficulties that, of course, the company’s management will have to overcome in the very near future: first of all, the use of the translator program “Pozetta” (which was written to convert code written for PowerPC for Intel processes).

Then the process is repeated – you will need to convert the code for ARM (which will require, respectively, “Pozetta-2”). Thus, as long as a translator is needed, there will inevitably be losses of about 30-40% of the processor power for the code translation process itself…
