Sources speaking to
Paul Thurrott have said that the
Surface Go, Microsoft’s latest miniaturized version of its flagship
Windows tablet, was originally intended to use an ARM processor. It reportedly wasn’t until Intel ‘petitioned Microsoft heavily’ that it went with a Pentium Gold processor.

The report deals with a response many had to the Surface Go: why did Microsoft choose an Intel processor for its smallest Surface tablet instead of an ARM-based one, considering the latter’s supposed benefits to battery life and mobile-centric use?

Not to mention that Microsoft was expected to set an example for Windows on ARM. Earlier this year, the Windows on ARM platform
debuted to poor performance, so an improvement was expected.

Why the last minute change?

It still remains unclear why Microsoft ultimately went with the Intel processor, but these issues with performance wouldn’t likely have been resolved before the Surface Go’s release.

Even the updated Snapdragon 850 processor for late-2018 Windows devices
isn’t likely to match the power that users have come to expect from Windows laptops and tablets running on Intel chips.

Furthermore, ARM-based Windows devices still cannot support a large number of apps that Intel and AMD-based ones inherently do.

This is because the vast majority of apps on
Windows 10 were created to interface with Intel’s x86 instruction set architecture, and therefore are incompatible with the ARM processor without emulation.



Not only does this emulation introduce an additional level of overhead on the ARM processor to drive the virtualized environment in which to run these apps, Windows 10 can only emulate 32-bit x86 apps so far – a majority of Windows 10 apps are 64-bit, but
this limitation is almost through.

What's even worse for ARM is that
Intel is publicly against this emulation and possibly prepared to lawyer up over it on patent infringement concerns.

All told, ARM’s success on Windows has been an uphill battle for years, and is likely to be that way for at least a while longer. App compatibility and performance issues are more easily solvable problems – Qualcomm’s already planning
an update following Snapdragon 850 for 2019 – than potential patent infringement lawsuits.

Intel, meanwhile, has had trouble keeping pace with rivals in moving onto smaller processor design architectures, with its 14-nanometer process now several years old and its 10nm process delayed to mid-2019.

This news shows how heated the competition in the silicon industry has become in the past few years.
