The release is the third firmware update for the Surface Pro X since it launched last November. As usual, the release focuses on improving system performance and service reliability. Looking at the changelog (see below), the firmware package is mostly focused on improving various Qualcomm hardware components. The Surface Pro X is Microsoft’s first proprietary foray into Windows 10 on ARM. ARM is provided by Qualcomm’s Snapdragon 8cx running under the box. Furthermore, the Surface Pro X is the first ever Windows device to a full AI engine. Surface Pro X leverages the 8cx to have Instant On and LTE Advanced Pro.
