An external graphics card can really boost the graphics performance of small devices in many cases. At times, it might even render a secondary desktop computer unnecessary. This kind of docking solution is especially helpful for a slim and lightweight laptop that has a strong processor but lacks a dedicated GPU. When used at home, this setup provides users with enhanced graphics capabilities for gaming or demanding activities like video editing. The new Gtbox G-Dock could be a great option, as it can hold a powerful GPU and connect to laptops or mini PCs with high bandwidth.

Power Supply and Connectivity

This eGPU dock comes with a built-in 800W power supply, making it suitable for even the most power-hungry graphics cards. It also supports USB PD, enabling the dock to provide up to 100 watts to a laptop or mini PC. However, it’s not the best to use a USB 4 connection for this eGPU dock, as it offers a significantly lower bandwidth compared to OCuLink, which is a better choice.

Design and Pricing

The G-Dock has dimensions of 8.8 x 4.3 x 2.3 inches. Interestingly, the graphics cards are placed on top of the dock, allowing them to protrude from all sides. This design means that nearly all modern GPUs should be compatible with this eGPU docking station. Currently, the G-Dock is priced at $239 directly from the manufacturer.
