Surface External Graphics

Currently, all standard external graphics processing units require Thunderbolt 3/4 technology to provide enough bandwidth (up to 40Gbps) for transferring graphics data between the laptop and the external GPU (eGPU). Unfortunately, all generations of Surface Go come with only a single USB-C 3.1 Gen 1 which has a maximum bandwidth of 5Gbps.
