What is the GPD G2?<\/h2>\n\n\n\n

The GPD G2<\/a> is a modular eGPU docking station for a desktop PCIe graphics card, connecting to compatible devices through MCIO 8i or USB4 v2.0. This GPD G2 review looks at its graphics expansion, twin USB-A ports, Gigabit Ethernet, M.2 storage provision and up to 100W Power Delivery.<\/p>\n\n\n\n

This GPD G2 review documents NVIDIA RTX 3090 gaming results recorded with a GPD BOX and GPD WIN 5, before assessing the enclosure\u2019s listed connectivity and expansion hardware. The frame-rate figures come from the recorded test log, while the port, power and compatibility information is drawn from the GPD G2<\/a> specification.<\/p>\n\n\n\n

For readers weighing up eGPU options<\/a>, the G2\u2019s key benefit is flexibility. Instead of committing to a dock with a built-in mobile GPU, you can install a compatible desktop graphics card, then upgrade that card later while keeping the enclosure, power supply and hub features.<\/p>\n\n\n\n

GPD G2 Overview<\/h2>\n\n\n\n

At roughly 6.19 \u00d7 4.71 \u00d7 7.16 inches (157.3 \u00d7 119.8 \u00d7 182 mm), the enclosure weighs 1.605 kg (3.5 lb). In this GPD G2 review<\/a>, the published aluminium-magnesium alloy and PC 94V-0 build point to a compact chassis intended to remain robust.<\/p>\n\n\n\n

The front houses the PCIe 5.0 x16 slot for a graphics card. A standard retention tab is fitted, while a covered M.2 2280 PCIe 3.0 x2 SSD slot sits beside it to add storage.<\/p>\n\n\n\n

Beneath it, the connections run from left to right as MCIO 8i, USB4 v2.0, two USB 3.2 Gen 2 Type-A ports and Gigabit Ethernet. Together, the M.2 bay, USB ports and network connection give the enclosure a hub function as well as its graphics-card role.<\/p>\n\n\n\n

The left-hand panel contains an LED-illuminated power button and the built-in power supply\u2019s air intake. On the right are the 12V-2\u00d76 ATX 3.1 GPU power connector, the power-supply exhaust and an IEC 60320 C14 AC input.<\/p>\n\n\n\n

GPD G2 Technical Specifications<\/h2>\n\n\n\n

This GPD G2 review<\/a> confirms the stated Gold-rated ATX 3.1 power supply, with published efficiency of at least 92%. The 12V-2\u00d76 output is specified for 800W of continuous total 12V power, and the required cables for connecting a graphics card are included with the enclosure.<\/p>\n\n\n\n

The published compatibility list covers NVIDIA GeForce GTX 10, GTX 16 and RTX 20, 30, 40 and 50 Series cards; AMD Radeon RX 400\/500, Vega, Radeon VII, RX 5000, 6000, 7000 and 9000 Series cards; and Intel Arc A and B Series cards. It also names selected workstation and data-centre families, but an individual build still requires checks for card size, cooling clearance, connector needs and host compatibility.<\/p>\n\n\n\n

The published GPD G2 compatibility list<\/a> categorises the listed GPU families below.<\/p>\n\n\n\n

GPU category<\/th>Published compatible families<\/th><\/tr><\/thead>
Consumer GPUs<\/td>NVIDIA GeForce GTX 10, GTX 16, RTX 20, RTX 30, RTX 40 and RTX 50 Series; AMD Radeon RX 400\/500, RX Vega, Radeon VII, RX 5000, RX 6000, RX 7000 and RX 9000 Series; Intel Arc A and Arc B Series<\/td><\/tr>
Workstation GPUs<\/td>NVIDIA Quadro K, M, P, A and RTX Series; AMD Radeon Pro WX, Pro W, Pro W5700, Pro W6000, Pro W7000 and AI PRO R9000 Series; Intel Arc Pro A and Arc Pro B Series<\/td><\/tr>

The MCIO 8i connection is the standout feature of the GPD G2<\/a> eGPU. GPD specifies PCIe Gen 4 x8 support for PCIe devices, including graphics cards, and up to 256Gbps of theoretical bandwidth; the GPD BOX is the first consumer host named in the testing record as supporting this connection.<\/p>\n\n\n\n

Where MCIO is unavailable on the host, USB4 v2.0 provides the alternative. GPD lists up to 80Gbps symmetric bandwidth or 120\/40Gbps asymmetric bandwidth, according to the USB4 v2.0 mode being used.<\/p>\n\n\n\n

USB4 v2.0 is backwards compatible with USB4, meaning the GPD G2 docking connection can also work with compatible GPD, AYANEO and ONEXPLAYER handhelds, plus mini PCs and ultrabooks. The final experience still depends on the host, cable, firmware and graphics card. Read our MCIO vs OCuLink vs USB4 article here<\/a>.<\/p>\n\n\n\n

GPD G2 Connectivity<\/h2>\n\n\n\n

With an MCIO-capable host, this is the highest-bandwidth route in the published specification, at up to 256Gbps theoretical bandwidth for graphics and general data. This GPD G2<\/a> review also highlights the value of its dual-connection design: MCIO can handle the graphics link, while USB4 v2.0 supplies the hub expansion and Power Delivery capability described by GPD.<\/p>\n\n\n\n

For many owners, USB4 v2.0 will be the connection of choice, whether they have a GPD BOX configuration or a backwards-compatible USB4 device. It is the more straightforward option across many new and existing hosts, while the USB-A ports, Ethernet and SSD bay make this more than a graphics enclosure; compatible Accessories<\/a> can use the integrated hub.<\/p>\n\n\n\n
