Beelink is open-sourcing its eGPU docking station — PCIe 4.0 x8 could become more common in docks

Beelink's now-open-sourced PCIe x8 eGPU dock, the Beelink EX Docking Station, with outlines of a mounted Nvidia RTX 40 Series Card and Beelink GTi14 or GTi12 Mini PC.

Beelink, a mini PC manufacturer, open sourcing its docking station. On X (formerly Twitter), the company posted that it was releasing the specifications, patents, and other details related to the EX Docking Station meant for use with its own PCs.

"Beelink is committed to continuing this trend by open-sourcing verified and mature technical specifications and patents, fostering collaboration with developers and peers to advance the entire industry," the company wrote. 

The original dock was sold for $159 from Beelink's website. The Beelink EX Docking Station is distinguished from similar eGPU docks due to its use of the PCIe x8 interface to connect the client PC to the docking station, rather than resorting to Thunderbolt or OCuLink. This direct use of PCIe 4.0 x8 makes it the most performant and low-latency solution of modern eGPUs, but you'll need a mini PC that supports PCIe x8 expansion first.
