Apple's announcement of its plans to move the Mac's processors from Intel to its own Arm-based "Apple Silicon" has sent shockwaves through the air. In the midst of all this, a former head of Mac development has expressed the opinion that a similar transformation is inevitable for high-end Windows PCs, and that Intel will be forced to develop its own Arm CPUs for Windows.

Jean-Louis Gassée became Apple's president of products in the late 1980s and led the development of the Macintosh II and Macintosh Portable, among other products. Although he left the company in 1990, it is known that his opposition to external licensing of the MacOS had a decisive influence on the future of the Mac. He also founded Be Inc. and was the driving force behind the introduction of BeOS to the world.

In a blog post, Gassée first argued that Apple's claims that Arm-based processors (Apple Silicon) offer superior power efficiency and processing power are believable. The iPad Pro with the A12Z (also based on Arm) has a Geekbench score equal to or better than his MacBook Pro.

The TDP (Thermal Design Power, the maximum amount of heat that can be dissipated by the design of the CPU) of the iPad Pro has not been revealed, but on the basis of the 18W power adapter (the MacBook Pro's power supply is over 60W), he speculates that the TDP can be significantly lowered without losing processing power.

And when comparing processing power to Intel's x86 chip-based PCs, given the performance of the (presumably starting point) A12Z, it's unlikely that the Apple Silicon Mac's advantage will remain below 25%. There is no way Microsoft is sitting on the possibility that such an Apple could take the lead with the most powerful PC on the market.

This means that if MS continues to improve Windows with Arm powered Surface devices, Windows PC companies such as Dell, HP and ASUS will follow suit and "Armize" to compete. Then, if everyone wants Windows with Arm processors, Intel will have no choice but to license Arm and offer competitive Arm SoCs for PC OEMs - Gassée predicts such a development.

It remains to be seen if Apple Silicon will have that much of an impact on Intel, but for MS, whose own company is also introducing Surface X and other Arm chip-based devices, the Mac switch to Arm-based could be a major turning point for MS. By extension, they might offer Windows 10 for Apple Silicon Mac BootCamp (which Apple hasn't even mentioned yet) to the general public to see what happens.
