When splitting it between power, data, and display, such as through the Surface Dock, users will get only two lanes of PCIe for the screen. What the Type-C Display Port can do for output depends on how it is used. It is not Thunderbolt 3 compliant, however, so there is no external GPU (eGPU) support. Surface Book 2 USB Type-CĪll Surface Book 2's have a USB Type-C 3.1 port instead of the mini DisplayPort found in the original Surface Book. There is also a full SDXC card reader and USB Type-C instead of a mini DisplayPort.
There are also two USB Type-A 3.1 (Gen 1) ports for data and charging out. Microsoft is still using its proprietary Surface Connect for power and the optional Surface Dock. Surface Book 2 portsĪll Surface Book 2s have the same port configuration regardless of size or model. Since the 13-inch Surface Book 2 with a Core i5 does not have a NVIDIA GPU, it needs neither a fan in the display or tablet area for the CPU nor one in the keyboard base for graphics. The 15-inch Surface Book 2 has multiple fans because the Intel Core i7 processor runs at a full 20W all the time, whereas the 13-inch Core i7 runs at 15W and therefore is passively cooled. 15-inch Core i7: Fan in display and tablet.
13-inch Core i7: No fan in display or tablet.How Microsoft cools the Surface Book 2 depends on the model. The more substantial 15-inch model, however, has a much more powerful NVIDIA GeForce GTX 1060 graphics card and 6GB of GDDR5 video memory.
