GPD Unveils Box Mini PC and G-Series eGPUs with High-Speed MCIO 8i Interface

GPD has officially introduced its latest Box mini PC and G-series external GPUs (eGPUs), both featuring advanced external PCIe interfaces designed to meet the demands of gaming and AI workloads. These new devices mark a significant step forward in connectivity and performance for compact computing solutions.

GPD Box Mini PC: Enhanced Connectivity with MCIO 8i

The GPD Box mini PC is built on the Panther Lake platform and stands out primarily for its innovative use of the MCIO 8i (Mini Cool Edge IO) port. Unlike traditional mini PCs that rely on USB4 or Thunderbolt 5, the GPD Box adopts the MCIO 8i interface, delivering full PCIe 5.0 ×8 bandwidth. This upgrade theoretically allows for bidirectional data transfer rates of up to 512 Gbps, although practical limitations exist. Since MCIO was originally developed for server environments, concerns remain about the port’s durability in consumer settings, where frequent plugging and unplugging are more common. Additionally, while the MCIO 8i port supports PCIe ×8, it is capped at 256 Gbps bidirectional bandwidth on PCIe Gen 5.

Beyond its headline interface, the GPD Box offers a comprehensive selection of ports. The front panel includes dual USB Type-A and Type-C ports, as well as a 3.5 mm audio jack. On the rear, users will find two additional USB Type-A ports, DisplayPort and HDMI outputs for multi-display setups, and dual Ethernet ports for robust network connectivity.

GPD G2 eGPU: High-Performance External Graphics

Launching alongside the Box mini PC, the GPD G2 eGPU enclosure is engineered for versatility and performance. It supports connections via both USB4 v2.0 and MCIO 8i, making it compatible with a wide range of devices beyond just the GPD Box. According to GPD, the G2 can accommodate high-end graphics cards such as the NVIDIA RTX 4090, with only a 2% performance loss—an achievement that surpasses the capabilities of Thunderbolt 5 and OCuLink interfaces.

The G2 eGPU dock is equipped with dual USB Type-A ports for peripherals, a USB4 port with 100 W Power Delivery charging, and a built-in PCIe SSD expansion slot for additional storage. The enclosure features its own integrated power supply unit, connected to the GPU via an externally routed 12v-2×6 cable. While GPD has not yet disclosed the PSU’s output, it is expected to be sufficient for powering high-performance GPUs like the RTX 4090.

Release Timeline and Future Details

GPD has not yet announced specific pricing or availability for the Box mini PC or G2 eGPU. However, the official announcement indicates a planned release in 2026. More detailed specifications and information are expected to be revealed as the launch date approaches.
