AMD may have secured a new design win for the upcoming Microsoft Surface notebook which would utilize its 3rd Gen Ryzen 4000 CPU & Navi based Radeon RX GPU. Spotted by tech leaker, Rogame (via NotebookCheck), the 3DMark listing reports a Microsoft device built entirely on the AMD CPU & GPU platform.

Last year, Microsoft announced its first-ever Surface Laptop (3) which featured a custom Ryzen CPU based on the Zen+ architecture and the Vega GPU. This year, Microsoft is preparing an even better variant featuring AMD's latest chips. Last year, the chip embedded inside the Surface Laptop 3 was known as Winston while this year, the codename will be Acton based on the internal PCI Ids for the Renoir lineup.
