The Surface Pro X is a 2-in-1 detachable tablet computer developed by Microsoft. It was developed alongside and was announced on 2 October 2019 alongside the Surface Pro 7 and Surface Laptop 3. Updated hardware was announced alongside Surface Laptop Go and Surface accessories on October 1, 2020 and September 22, 2021. The device starts at $899.99 USD / £849.99.
The Surface Pro X comes with a Microsoft SQ1 or SQ2 ARM processor, which the company claimed has three times the performance of an x86 MacBook Air, whilst also having a 13-hour battery life. This is due to the increased power efficiency of ARM processors compared to traditional x86 processors. Microsoft has previously used ARM processors in the discontinued Surface RT and Windows Phone devices.
Microsoft now offers a Wifi-only version of the device as announced at their Surface Event on September 22, 2021.
