Introducing the G1 — the world’s smallest mobile graphics card expansion dock that acts as a docking station and external graphics card (eGPU) for laptops and handheld gaming PCs. Created by Chinese company GPD, the G1 aims to boost gaming capabilities and serve as an anchor for mobile workers. The device includes an AMD Radeon RX 7600M XT chip, HDMI 2.1, two DisplayPort 1.4 video outputs, a USB 4/Thunderbolt 4 connector to dock and charge, and something called Oculink.
## Features of the G1
The G1 is only slightly over an inch thick (29.8mm), about nine inches long (225mm), and four and a third inches deep (111mm). Additionally, it comes with an integrated power supply. The G1 is equipped with a USB 4/Thunderbolt 4 connector for docking and charging, an AMD Radeon RX 7600M XT chip, HDMI 2.1, and two DisplayPort 1.4 video outputs.
## About GPD
Based in Shenzhen, China, GPD has been making a name for itself amongst PC gamers who are interested in the recent handheld gaming boom. While Valve’s Steam Deck and Asus’ upcoming ROG Ally are popular among gamers, GPD has been working on similar gaming handhelds like Ayaneo 2S and GPD’s Win Max 2 for years.
## Compatibility
If you’re using a laptop or desktop, GPD shares what cards you need to take full advantage of the G1 dock. Those in the know are paying attention to other PC gaming handhelds like the Ayaneo 2S and GPD’s Win Max 2. Both companies will sell versions that feature an Oculink connector, which is a connector for PCI-Express that you would more typically see in enterprise server racks.
## Unique Oculink Connector
The G1 is unusual in that it uses Oculink, which provides reliable and better GPU performance (GPD claims up to 63Gbps bandwidth) compared to the more widely supported USB4 and Thunderbolt-based eGPUs. Weak desktop computers can also get in on the action with an Oculink adapter card. However, the challenge with Oculink is that it doesn’t carry the power and data required to fully dock and charge a PC, making use of a USB-C connector necessary.
## Cost
GPD has not yet revealed how much the G1 will cost.
## Crowdfunding
The G1 is on Indiegogo, but the campaign has not yet begun. GPD hopes to raise $20,000HKD to fund the project. Considering that the company has successfully funded almost every product it has shipped, there is a high chance that the G1 will see the light of day.
## Conclusion
GPD’s G1 is the world’s smallest mobile graphics card expansion dock that establishes a combined docking station and eGPU. The G1 uses an unusual Oculink connector, which gives you a reliable and better GPU experience compared to widely-supported USB4 and Thunderbolt-based options. Oculink, however, does not carry the power and data required to fully dock and charge a PC, making use of a USB-C connector necessary. Although GPD has not yet shared the price of the G1, crowdfunding is currently ongoing.
