Frequently Asked Questions #
GPD G2 #
What is the GPD G2?
The GPD G2 is an external GPU docking station with the world’s first MCIO dual-port eGPU dock. It is designed to connect compact systems to desktop graphics cards while also adding extra connectivity and storage options
What is the main purpose of the GPD G2?
Its main job is to let compatible devices use desktop-class PCIe graphics cards externally. It is a high-bandwidth graphics expansion platform rather than just a simple dock.
What makes the GPD G2 different from a typical eGPU dock?
The biggest differentiator is MCIO. The MCIO 8i plus USB4 v2.0 connectivity, along with a much more serious power design than most compact eGPU docks.
Which devices is the GPD G2 designed to work with?
The GPD G2 can be used for home PCs, high-end gaming handhelds, laptops, workstations, servers, and even some HPC-style use cases. The most relevant requirement is compatible connectivity, especially MCIO or USB4-class support depending on the device.
Does the GPD G2 only work with GPD devices?
No. It can be used with a range of PCs and handhelds, not only GPD hardware
What is MCIO on the GPD G2?
MCIO is the high-bandwidth connection GPD is using to push the G2 beyond a more conventional USB4-only eGPU dock. On the G2, the MCIO 8i link supports PCIe devices, including graphics cards, via PCIe Gen 4 x8
What is the difference between using MCIO and USB4 on the GPD G2?
MCIO is the more performance-focused path, while USB4 adds compatibility and dock-style functionality. The USB4 connection handles eGPU functionality when used independently, while simultaneous MCIO plus USB4 connection is needed to enable hub functionality alongside MCIO
Can the GPD G2 work as more than just a GPU dock?
Yes. Besides graphics support, it also adds USB ports, Ethernet, and an M.2 storage slot
What ports does the GPD G2 have?
There is one USB4 v2.0 port, two USB 3.2 Gen 2 Type-A ports, one RJ45 Ethernet port, one MCIO 8i connection, and one M.2 2280 slot
Does the GPD G2 have Ethernet?
Yes. It includes one RJ45 Ethernet port rated at 10/100/1000 Mbps auto-negotiation.
Does the GPD G2 have USB-A ports?
Yes. there are two USB 3.2 Gen 2 Type-A ports running up to 10Gbps.
Can the M.2 slot on the GPD G2 be used as bootable external storage?
Yes. the M.2 slot supports external storage booting.
How fast is the M.2 storage slot on the GPD G2?
It has a M.2 2280 slot running at PCIe 3.0 x2, converted from USB 3.2 Gen 2. That means it adds useful storage expansion, but it is not being positioned as the highest-speed NVMe implementation.
Does the GPD G2 include a GPU?
No, you would need to buy your own GPU.
What graphics card slot does the GPD G2 have?
It is a PCIe Gen 5 x16 slot.
Does the GPD G2 support NVIDIA GeForce RTX 4090 or RTX 5090-class GPUs?
Yes, including 4090 and 5090-class models.
Does the GPD G2 support AMD and Intel graphics cards too?
Yes. There is broad support across AMD Radeon and Intel Arc product families as well as NVIDIA cards.
Does the GPD G2 support workstation or professional GPUs?
The GPD G2 supports borth gaming and professional GPUs. NVIDIA’s lineup spans multiple generations, starting from the GeForce GTX 10 Series (Pascal) and RTX 20 / GTX 16 Series (Turing), progressing through the RTX 30 Series (Ampere) and RTX 40 Series (Ada Lovelace), and concluding with the latest RTX 50 Series (Blackwell). AMD’s roster traces its evolution from the older Radeon RX 400 / 500 Series (GCN 4.0) and RX Vega Series (GCN 5.0) into its modern era with the RX 5000 (RDNA 1.0), RX 6000 (RDNA 2.0), RX 7000 (RDNA 3.0), and RX 9000 Series (RDNA 4.0). Finally, Intel is represented by its dedicated Arc graphics families: the Arc A Series (built on the Xe HPG architecture) and the Arc B Series (utilizing the newer Xe2 HPG architecture).
For professional GPUs. NVIDIA’s professional evolution spans from the earlier Quadro K (Kepler), M (Maxwell), and P (Pascal) series to the modern RTX A Series (Ampere) and RTX PRO Series (Blackwell). AMD’s workstation offerings transition from the legacy Radeon Pro WX and W Series (GCN architecture) through the modern Radeon Pro W6000 (RDNA 2) and W7000 (RDNA 3) series, culminating in the Radeon AI PRO R9000 Series (RDNA 4). Finally, Intel is represented by its dedicated professional GPUs: the Arc Pro A Series built on the Xe architecture and the succeeding Arc Pro B Series utilizing the newer Xe2 architecture.
NVIDIA’s enterprise solutions span from the legacy Tesla Series (encompassing multiple architectures including Kepler, Maxwell, Pascal, Volta, and Turing) to its modern, high-performance PCIe accelerators, such as the A100 (Ampere), H100/H200 (Hopper), and the B100 (Blackwell). AMD’s compute-focused Instinct lineage evolves from its earlier GCN-based cards (MI6, MI8, and MI25) into its purpose-built CDNA architectures, represented by the MI100 (CDNA 1), MI200 Series (CDNA 2), MI300 Series (CDNA 3), and the MI350 Series (CDNA 4). Finally, Intel’s data center portfolio includes the Flex and Max Series GPUs (utilizing Xe-HPG and Xe-HPC architectures), the specialized Gaudi 3 AI Accelerators, and the “Crescent Island” platform powered by the Xe3P architecture.
Can the GPD G2 be used for AI, compute, or server-style workloads?
Yes, workstation, server, and HPC-style scenarios rather than only gaming or creator use.
How much power can the GPD G2 deliver?
The GPD G2 uses a Gold-rated ATX 3.1 power design with 800W continuous total 12V output.
What power connector does the GPD G2 use for GPUs?
It has a 12V-2×6 GPU power connector and complies with ATX 3.1 GPU requirements.
Does the GPD G2 need its own power supply?
Yes. This is not a bus-powered accessory. The power supply supports 100 to 240V AC input, a Gold-rated ATX 3.1 design, and an IEC C14 power socket aka ‘kettle lead’ as you would find on a standard desktop PC power supply.
Can the GPD G2 charge a handheld or laptop?
Yes, up to a point. The USB4 v2.0 port supports PD 3.0 charging up to 100W.
What does the USB4 power delivery support on the GPD G2 mean in practice?
It means the dock can potentially power or charge a compatible handheld or laptop over USB4 while also acting as an expansion device. There is support for 5V, 9V, 12V, 15V, and 20V power delivery profiles up to 100W.
What performance can you expect from the GPD G2?
GPD’s headline claim is that an RTX 4090 would see only around a 2% performance loss on the G2. That sounds impressive, but it should be treated carefully until fuller benchmark methodology and independent reviewers validate it.
Is the GPD G2 better than a typical USB4 eGPU dock?
The MCIO-focused design and much more aggressive bandwidth and power positioning suggest a step above more limited USB4-only docks
What operating systems does the GPD G2 support?
Windows 11 and Linux distributions
What are the GPD G2’s dimensions and weight?
The dimensions are 157.3 × 119.8 × 182 mm (6.19 x 4.71 x 7.16 inches) with a net weight of 1605 g (3.5 lbs).
What materials is the GPD G2 made from?
It is made from aluminum-magnesium alloy and PC 94V-0.
When is the GPD G2 release date?
No release date has been announced yet.
Has the GPD G2’s price been announced?
Currently not yet. We hope to have final pricing soon.
