One Dock, 1st dual-port eGPU dock, ThunderBolt&OCulink(M.2), Assembly, Weighing and Benchmark

[Introduction] May I introduce our new eGPU dock: One Dock, the 1st eGPU dock which can support both ThunderBolt and OCulink (M.2) ports. This is a work designed by community cooperation. It is designed for all laptops & Win handheld PCs. The design idea is to show the original beauty of your expensive GPU. It's an invisible GPU holder with minimum desktop space, can be used for GPU cards of any size. It's overall size is 170 * 47 * 33mm(). With ThunderBolt, One Dock provides 85W PD power supply. It uses a JHL6540 ThunderBolt 3 controller. With OCulink, One Dock can get a MAX bandwidth of 64Gbps(M.2 PCIe x4 4.0), which greatly reduces the performance loss. One Dock requires an external 20V DC7450 power supply (standard DELL/HP laptop power supply adapter), GaN is recommended. The rated power of the power supply shall be greater than the sum of the MAX power consumption of GPU card and the PD power supply. A 20V-12V DCDC step-down module is built in to supp
