First making its debut in Microsoft's Surface Laptop 3, AMD's Ryzen 7 3780U and Ryzen 5 3580U Microsoft Surface Edition processors brought four cores and eight threads to the table, but a recent leak suggests the Surface Laptop 4 will receive an upgrade to eight cores and sixteen threads thanks to AMD's Ryzen 7 4800U.

Notorious hardware leaker APISAK recently spotted a 3DMark entry for the AMD Ryzen 7 4800U, and in doing so, a bit of information in terms of the potential machine containing this processor was leaked. The 3DMark entry lists the vendor of the device as Microsoft, which leads to speculation as to whether or not the Ryzen 7 4800U may appear in the Surface Laptop 4, or if the device tested is a separate entity. Considering Microsoft made the move to Ryzen with the Surface Laptop 3 with great success, chances are that Microsoft will move forward with its partnership with AMD for the next generation.
