George Hotz, representing Comma.ai and Tinygrad, today announced the availability of new eGPU docks. The offerings include the Tiny Chestnut eGPU Dock and the Chestnut Dock, which is bundled with an AMD Radeon RX 9060 8GB GPU. A key feature of both docks is their provision of PCIe Gen4 x4 connectivity, leveraging the USB4 standard. Hotz highlighted that the docks are designed with open-source firmware. This approach aims to provide users and developers with transparency and control over the hardware's core functionality.
