Lenovo introduces an OCuLink interface dock for connecting desktop video cards to laptops.

At the CES 2024, Lenovo unveiled its latest TGX Dock, a unique external docking station enabling discrete graphics card connectivity to laptops and mini-PCs. The standout feature is its OCuLink (Optical-Copper Link) interface which offers a faster data transfer rate of 64 Gbps; this is a significant leap compared to the 40 Gbps capability of Thunderbolt 4.

The TGX Dock was showcased in tandem with the ThinkBook 14i Gen 6+ laptop, demonstrating its ideal use. The laptop features an appropriate connector, resembling DisplayPort but not interchangeable. The Dock measures 370 × 210 × 180 mm.

Lenovo officially confirmed TGX Dock’s support for the GeForce RTX 40 series video cards. The Dock can house the RTX 4060 Ti, RTX 4070 or RTX 4090, provided they’re under 358 mm in length. Lenovo recommends using this graphic prowess chiefly to boost the AI generative model performance of the ThinkBook 14i Gen 6+ rather than for gaming enhancements.

The TGX Dock features its own power supply unit. Demonstrated at CES 2024, Lenovo used the 1200W FSP1200-40ALA power supply unit with a GeForce RTX 4070 graphics card. It’s connected to the Dock via a 24-pin connector affixed to a PCIe riser adapter, and a 12+4-pin connector for the graphics card. The Dock also contains a 120mm fan for additional cooling.

The TGX Dock is designed for easy assembly, requiring only one screw to be loosened at the back. The unit is built with a small metal handle for ease of accessibility.

According to Lenovo, the ThinkBook 14i Gen 6+ laptop and the TGX Dock for external graphics cards will go on sale in the second quarter of the year. However, it should be noted that not all markets will see this release, with EMEA regions (Europe, the Middle East and Africa) not included.
