Comment on Chestnut – eGPU dock with open-source firmwareparent

Comments

My understanding is both USB 4 and TB use PCIe tunneling. Surely at this price point we’re looking at a USB 4 device. Thunderbolt has historically cost more due to licensing, which is now free I believe, but there’s still specialized hardware and requirements manufacturers need to adhere to.

It seems to support USB4 with what they call "stock firmware". They haven't clarified what that means, but my assumption has been that it's a binary blob made by the manufacturer of their microcontroller that doesn't support all of their fancy debugging features (thus actually turning my into an Aliexpress special eGPU dock with a high quality buck converter).
