Rumor mill: Fans of Microsoft's Surface Laptop 3 who prefer AMD to Intel will be pleased to hear that team red's CPUs are no longer limited to the 15-inch model in the successor. According to reported Surface Laptop 4 specs, the 13.5-inch version will also offer processors from both Intel and AMD when it launches in April.

WinFuture (via Windows Central ) published alleged details of the Surface Laptop 4. The specs show that both sizes can be configured with Intel's 11th-gen Tiger Lake chips (Core i5-1145G7, Core i7-1185G7) or AMD's 4000 Mobile Series CPUs ("Surface Edition" Ryzen 5 4680U, Ryzen 7 4980U).

The current 15-inch Surface Laptop 3 can be specced with the Ryzen 5 3580U and Ryzen 7 3780U, so Microsoft is upgrading AMD's processors in the new models, though it's strange to see the Zen 3-powered Ryzen Mobile 5000 chips not being used.

Elsewhere, the 3:2 aspect ratio remains from the Surface Laptop 3, as do the 2256 x 1504 (13.5 inch) and 2496 x 1664 (15 inch) resolutions. Memory reaches 32GB and storage maxes out at 1 TB, though only if you opt for an Intel CPU; AMD models get a maximum of 16GB of RAM and 512GB of storage. GPUs are simply listed as "Iris Plus Graphics 950" and "Radeon Graphics."

The Surface Laptop 4 does look like it'll be a smartphone-style iterative upgrade, with few changes beyond the internals. These reported specs might not be entirely accurate, of course, but we should find out for sure in a few weeks.
