At its Surface event today, Microsoft announced two custom chips. The first of these is for the Surface Laptop 3, and is based on AMD’s Ryzen 3700U. The second, powering the Surface Pro X, is dubbed as ‘SQ1’ and is based on Qualcomm’s Snapdragon 8cx (Compute eXtreme) SoC launched last year. Now, we’ve got some additional details for the SQ1. Take a look below for them.

The Snapdragon 8cx is Qualcomm’s first chip designed specifically for Windows Always Connected PCs. This SoC features eight Kryo 495 cores, divided into two clusters of four cores each for high-performance and power efficiency. The cores’ frequency isn’t known, but Samsung’s Galaxy Book S that’s powered by the 8cx has a 2.84 GHz base frequency.
