2. Connecting the eGPU Dock:
The AD-GP1 eGPU Dock can be connected to your Mini PC or compatible laptop via two primary methods: USB4 or Oculink.
- USB4 Connection: Use a certified USB4 cable to connect the eGPU Dock's USB4 port to a compatible USB4 or Thunderbolt port on your host device. This connection supports up to 40 Gbps transfer speeds and 8K@60Hz display output. It also provides 100W power delivery to the host device.
- Oculink Connection: For the fastest possible connection, use an Oculink cable to connect the eGPU Dock's Oculink port to a compatible Oculink port on your host device. This method offers higher bandwidth and more stable transmission, directly accessing the PCIe bus for near-native performance.
- Connect your display(s) to the HDMI 2.1 or DisplayPort 2.0 outputs on the eGPU Dock.

Operating Instructions
Powering On/Off:
- Press the power button on the Mini PC to turn it on.
- To shut down, use the operating system's shutdown function.
Optimizing Performance with eGPU:
For optimal gaming and graphical performance, it is recommended to connect your display directly to the eGPU Dock's output ports (HDMI or DisplayPort) and disable the internal display of your laptop (if applicable). This ensures that the dedicated AMD Radeon 7600M XT GPU handles all graphical rendering, maximizing frame rates and visual quality.
The eGPU's dedicated 8GB GDDR6 video RAM significantly enhances performance for graphically intensive tasks, including gaming, video editing, and local AI processing, by offloading these tasks from the system's main CPU and integrated graphics.
Network Connectivity:
The Mini PC supports dual 2.5G Gigabit Ethernet for high-speed wired network connections. For wireless connectivity, it features Super Speed Wi-Fi 6E and Bluetooth 5.2, providing fast and reliable wireless performance.
