eGPU Gaming, AI Development, Content Creation, Workstation Docking, Handheld Gaming Docking, Mini PC GPU Expansion
Overview
The ONEXGPU (1st Gen) is the original mobile external GPU from ONEXPLAYER (ONE-NETBOOK), launched in late 2023 via Indiegogo crowdfunding. It features an integrated AMD Radeon RX 7600M XT mobile GPU with RDNA 3 architecture, 8GB GDDR6 VRAM, and a built-in 240W GaN power supply that eliminates the need for a separate power brick. The compact aluminum chassis (196 x 120 x 32mm, 869g) connects via OCuLink (PCIe 4.0 x4, 64Gbps) or USB4 (40Gbps, 65W PD, compatible with Thunderbolt 4/3) to gaming handhelds, laptops, mini PCs, and ultrabooks, delivering desktop-class 1080p and 1440p gaming performance. Beyond raw graphics acceleration, it includes a built-in M.2 2280 NVMe PCIe 4.0 SSD expansion slot, dual display outputs (HDMI 2.1 + DP 1.4a), two USB-A 3.2 Gen2 ports, an SD 4.0 card reader, and 65W USB4 Power Delivery, making it a versatile eGPU and docking station for gaming, content creation, AI development, and portable workstation setups.
Key Highlights
- AMD Radeon RX 7600M XT mobile GPU with RDNA 3 architecture (8GB GDDR6, 32 CUs, 2.3 GHz, 120W TGP) — delivers desktop-class 1080p and 1440p gaming performance outperforming RTX 4060 Mobile and RTX 3070 Laptop
