GPD (GamePad Digital)
GPD G1 Mobile eGPU
Overview
The GPD G1 is the world's smallest mobile external GPU enclosure, featuring an integrated AMD Radeon RX 7600M XT mobile GPU with RDNA 3 architecture, 8GB GDDR6 VRAM, and a built-in 240W GaN power supply — eliminating the need for an external power brick. It connects via OCuLink SFF-8612 (PCIe 4.0 x4, 64Gbps) or USB4 (40Gbps, compatible with Thunderbolt 3/4) to gaming handhelds, laptops, mini PCs, and ultrabooks. With triple display outputs (2x DP 1.4a + 1x HDMI 2.1), three USB-A 3.2 Gen2 ports, an SD 4.0 card reader, and 60W USB4 Power Delivery, it serves as both a high-performance eGPU and a compact desktop docking station for gaming, AI development, content creation, and workstation productivity.
