All-AMD Microsoft Surface notebook with Ryzen 5 4500U and RX 5300M spotted on 3DMark

Microsoft promised to release more AMD-based Surface laptops last year, and, now that the Ryzen 4000 “Renoir” APUs are available, we finally get to see some hardware specs for this year’s Surface models. One of the variants was recently spotted by Twitter user _rogame in the 3DMark database, and it looks like this could be a 13.5-inch model with an unusual hardware configuration that includes a Renoir APU plus a discrete GPU also manufactured by AMD.

_rogame believes this could be a Surface Book 3 variant, although another twitter user points out that the detachable screen feature on the Surface Book models uses Intel patents, so Microsoft might not want to mix and match vendors this way. It could very well turn out to be a Surface Laptop 3 or a Surface tablet. In any case, the 3DMark database entry shows a Ryzen 5 4500U APU coupled with an entry-level RX 5300M dGPU.

An interesting thing to point here is that the test identified the manufacturing process as 0 nm along with a 0 W TDP for the CPU. This could be due to Microsoft using custom SKUs that have different codenames and revision numbers. _rogame identified three “Acton” SKUs in Microsoft’s drivers, so this could be one of those.
 
We could expect to see Ryzen 5 4500U / 7 4700U + RX 5300M configurations for the 13.5-inch laptop, while the 15-inch variant could be powered by Ryzen R5 4600U / 7 4800U + RX 5500M/ RX 5600M combos.
