Is Microsoft developing its own Arm processor for servers or Surface?

Bloomberg, a major US economic media, reports that Microsoft is developing its own chips designed with the Arm architecture for data centers or the Surface series.

Chips that use the Arm architecture have already been independently developed by Apple and Amazon. Apple has released a Mac with a proprietary 'M1' chip.

In addition, Amazon has developed the Arm-based processor ' Graviton 2 ' for Amazon Web Services (AWS). You can already use this Graviton 2 with M6g instances of AWS EC2.

Bloomberg said that Microsoft is developing an Arm processor for data centers as a testimony from Microsoft employees, and at the same time is seeking to develop an Arm processor for Surface, which is a mobile PC. Bloomberg sees the development of Arm processors for data centers as 'likely'.

Intel's Xeon series is often used as the processor for servers, and the market share is about 90%. However, some Xeon processors are very expensive, and it costs enough to change a light car to install one.

In addition, Microsoft has already adopted the Arm-based processor developed by Qualcomm on some Surface PCs. In October 2020, with the announcement of Surface Pro X with a Microsoft SQ2 processor that adopted the Arm architecture, x64 emulation function was added to the Arm version of Windows 10.

Since models with Arm processors have already been announced and support for Windows 10 for Arm is also progressing, it is quite possible that Microsoft will proceed with the development of Arm processors for Surface.

Microsoft and Arm declined to comment directly on whether Microsoft is developing Arm-based processors, but Microsoft spokeswoman Frank Shaw said, 'Silicon forms the basis of technology. We are investing in unique features in areas such as design, manufacturing and tools to promote and strengthen partnerships with various chip providers, 'implying the development of Arm processors.'
