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

The GPD G2<\/a> is a modular eGPU docking station that accepts a desktop PCIe graphics card and connects to a compatible host through MCIO 8i or USB4 v2.0. This GPD G2 review covers its graphics expansion, two USB-A ports, Gigabit Ethernet, M.2 storage support and up to 100W Power Delivery.<\/p>\n\n\n\n

This GPD G2 review records NVIDIA RTX 3090 gaming results with a GPD BOX and GPD WIN 5, then examines the enclosure\u2019s published connectivity and expansion features. The performance figures are observed results from the supplied test record; the port, power and compatibility details are based on the current GPD G2<\/a> specification.<\/p>\n\n\n\n

For anyone comparing eGPU options<\/a>, the practical appeal is modularity. Rather than buying a dock with a fixed mobile GPU, the G2 lets you select a compatible desktop graphics card and replace it later, while retaining the enclosure, power supply and hub functions.<\/p>\n\n\n\n

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

The enclosure measures approximately 6.19 \u00d7 4.71 \u00d7 7.16 inches (157.3 \u00d7 119.8 \u00d7 182 mm) and weighs 1.605 kg (3.5 lb). This GPD G2<\/a> review found its published aluminium-magnesium alloy and PC 94V-0 construction is intended to provide a compact but sturdy chassis.<\/p>\n\n\n

On the front is the PCIe 5.0 x16 slot for the graphics card. It uses a standard retention tab, and a covered M.2 2280 PCIe 3.0 x2 SSD slot sits alongside it for storage expansion.<\/p>\n\n\n

Below that, from left to right, are the MCIO 8i port, a USB4 v2.0 port, two USB 3.2 Gen 2 Type-A ports and a Gigabit Ethernet port. The M.2 slot, USB ports and network connection give the enclosure a hub role alongside its graphics-card function.<\/p>\n\n\n\n

The left side has the LED-lit power button and the air intake for the built-in power supply. The right side has the 12V-2×6 ATX 3.1 GPU power connector, the power-supply air outlet and an IEC 60320 C14 AC power input.<\/p>\n\n\n\n

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

The GPD G2<\/a> review specification check confirms a built-in Gold-rated ATX 3.1 power supply with stated efficiency of at least 92%. Its 12V-2×6 output is rated for 800W continuous total 12V power, and the enclosure includes the cables needed to connect the G2 to a graphics card.<\/p>\n\n\n\n

Compatibility spans 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. The list also includes selected workstation and data-centre families, but card dimensions, cooling clearance, connector requirements and host compatibility still need checking for an individual build.<\/p>\n\n\n\n

The published GPD G2 compatibility list<\/a> groups the supported families as follows.<\/p>\n\n\n\n

GPU category<\/strong><\/th>Published compatible families<\/strong><\/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>
Data-centre GPUs<\/td>NVIDIA Tesla, T4, A100, H100\/H200 and later PCIe products; AMD Instinct MI8, MI6, MI25, MI100, MI200, MI300 and subsequent PCIe products; Intel Max and Flex Series<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

The MCIO 8i port is the headline connection on the GPD G2 eGPU. GPD specifies PCIe Gen 4 x8 support for PCIe devices, including graphics cards, with up to 256Gbps theoretical bandwidth; the GPD BOX is the first consumer host named in the supplied draft as supporting this connection.<\/p>\n\n\n

If the host does not have MCIO, the USB4 v2.0 connection is the alternative. GPD specifies up to 80Gbps symmetric bandwidth or 120\/40Gbps asymmetric bandwidth, depending on the USB4 v2.0 mode in use.<\/p>\n\n\n\n

USB4 v2.0 remains backwards compatible with the USB4 standard, so the GPD G2 docking connection can also be used with compatible GPD<\/a>, AYANEO<\/a> and ONEXPLAYER<\/a> handhelds, as well as mini PCs and ultrabooks. The host, cable, firmware and graphics card will still affect the experience.<\/p>\n\n\n\n

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

For a host with MCIO, that is the highest-bandwidth connection in the published specification, with up to 256Gbps theoretical bandwidth for graphics and general data transfer. In this GPD G2 review, the dual-connection design is also important: MCIO can carry the graphics connection while USB4 v2.0 provides the hub expansion and Power Delivery function.<\/p>\n\n\n

Most users will likely connect through USB4 v2.0, whether they are using a GPD BOX configuration or a backwards-compatible USB4 host. That is the simpler route for many newer and older devices, and the two USB-A ports, Ethernet and SSD bay make the unit more than a graphics enclosure; suitable accessories<\/a> can be connected through the integrated hub.<\/p>\n\n\n\n
