Comma.ai has released the Chestnut and Tiny Chestnut eGPU docks, which convert PCIe Gen4 x4 to USB4 and run open-source firmware, with the Chestnut variant including an AMD Radeon RX 9060 8GB GPU.
The open-source firmware distinguishes this dock from proprietary eGPU enclosures, giving engineers the ability to audit, modify, or extend the dock's behavior. This transparency matters for workflows that require verified hardware behavior or custom functionality that closed firmware cannot provide.
