Microsoft's new Surface Pro X is now available in stores.

Microsoft's vision for Surface Pro X was to take a mobile architecture and push the technology to make it a fully functioning powerful PC. The company created a piece of custom silicon, designed in partnership with Qualcomm. Surface Pro X is powered by the Microsoft SQ1 processor, creating a device that enables a combination of pixels, performance, thinness, battery life and constant LTE connectivity.

This chip brings Snapdragon mobile DNA and an integrated AI accelerator together with power. While ARM chips normally run in the 2-watt range, Microsoft SQ1 started with a phenomenal 7 watts of power by changing the chip itself. Microsoft sayt it redesigned the GPU and other silicon IP to create a product that’s 3x more performant per watt than Surface Pro 6. This means better battery life, a lighter and thinner product, and performance, all while running full Windows, all the Office apps, Edge and Chrome.

At 5.3mm thin at its thinnest point and 1.68lbs, the Surface Pro X is portable and always connected with LTE advanced. With the thinnest bezels of any 2-1 on the market, the display provides a 13” screen in a 12” form factor, along with high contrast and high readability, and 2880×1920 resolution at 267 dpi.

With the new Surface Pro X Signature Keyboard and Surface Slim Pen, you can create with typing, pen or touch. With the Surface Pro X Signature Keyboard, the Pen stores securely and automatically recharges.

The Surface Pro X is available in the US and Canada today, and additional markets where Surface is sold in the coming weeks.
