Best answer: No, the USB-C ports on the original Surface Go and new Surface Go 2 do not support Thunderbolt 3. You still get data transfer, display out, and charging, but not the extra speed associated with Thunderbolt 3. If you’re looking to add connectivity, a docking station will do the trick for either device.
What can the Surface Go, Go 2’s USB-C ports do?
The USB-C port in the Go 2 didn’t get the same treatment as the Pro 7, Pro X, and Laptop 3, with support for DP 1.4 DSC that allows for dual 4K display support at a 60Hz refresh rate with nothing more than a hub or monitor supporting daisy-chaining.
Microsoft’s USB-C Travel Hub is a solid addition here, adding USB-C, USB-A, Ethernet, HDMI, VGA, and 3.5mm audio ports. But if you’d like to keep the USB-C on the Go and Go 2 free, there’s always the proprietary Surface Connect port.
What about the Surface Connect port?
The Surface Dock 2 adds four USB-C ports (two meant to handle video out), two USB-A 3.2 ports, Ethernet, and 3.5mm audio. It’ll also charge your Go 2 when connected, allowing you to forget about whether or not your device is charged when you need to leave the house or office.
While the Surface Dock 2 won’t work with the original Surface Go, there are docking options out there that work with the USB-C port. Something like CalDigit’s USB-C Pro Dock will connect to the original Go’s USB-C port (or the Go 2’s USB-C port) and add two DisplayPort 1.2, three USB-A 3.2, USB-C 3.2, an SD card reader, Ethernet, and 3.5mm audio. It’ll also charge your Go when connected.
For the Go 2
Updated with modern ports
The Surface Dock 2 brings much-needed updates to the original, adding in four USB-C ports alongside the usual Ethernet, USB-A, and 3.5mm jacks.
