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.

AMD To Power Upcoming Microsoft Surface Book 3 With Its Zen 2 Ryzen 4000 CPU & Navi Based Radeon RX Discrete Graphics

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.

As per the specifications, we are looking at the Ryzen 5 4500U CPU which is part of the Ryzen 4000 U-series family. The CPU features 6 cores and 6 threads. The clock speed for this chip are reported at 2.30 GHz base and 4.00 GHz boost. There is a total of 11 MB of cache available of which 8 MB is L3 and 3 MB is L2.

The AMD Ryzen 4000 series processors are based on the Zen 2 core architecture and fabricated on the advanced TSMC 7nm FinFET process allowing for higher efficiency and longer battery times. The Ryzen 5 4500U has a TDP of 25W which is configurable down to 10W & I believe that the cTDP is what Microsoft would be aiming for to increase battery times with a balanced power scheme.
