Microsoft is expected to reveal the Surface Laptop 4 next month, but it looks as though the specs for both the 13.5-inch and 15-inch models have leaked ahead of the launch.
In terms of looks, we're not expecting much to change from this new generation of Surface laptops, but what's inside may surprise some people.
As WinFuture reports (translated), it looks as though Microsoft has opted for the latest Intel processors, but anyone preferring an AMD chip will have to make do with older processors.
Rather than selecting the latest Ryzen 5000 series chips, the Surface Laptop 4 will be available with 4000 series options.
The chip options are expected to include Intel's 11th generation Core i5-1145G7 and Core i7-1185G7 alongside AMD's Ryzen 5-4680U and Ryzen 7-4980U.
The GPU is therefore either Intel's Iris Plus Graphics 950 or AMD's Radeon Graphics.
RAM options are limited to 8GB, 16GB, or 32GB, while storage options include a 128GB, 256GB, 512GB, or 1TB PCIe NVMe SSD.
For the Surface Laptop 3, Microsoft used Intel chips for the 13.5-inch model and AMD chips for the 15-inch model.
Will it do the same for the Surface Laptop 4? WinFuture believes all four processor options will be available for either model, so you won't be limited if processor choice is high on your list of priorities.
Other features of note include the continued use of a 3:2 format touch screen display on both laptops, a milled aluminum casing, and a 49Wh battery.
That battery size is important as the Surface Laptop 3 used a 45.8Wh battery and claimed 11.5 hours of battery life.
Microsoft is moving to a larger battery and using more efficient processors, so that could result in a significant boost to battery life in these new laptops.

When Daxdi reviewed both Surface Laptop 3 models we liked what we found.
The 13.5-inch model is an excellent ultraportable with solid battery life and a snappy, satisfying keyboard.
On the other hand, the 15-inch model is light for its size, had a comfortable touchpad and made for an excellent mainstream machine.
It seems likely this is set to continue for the new models, but we'll have to wait until next month to find out for sure.
