This bridge - does it actually support host PCIe->thunderbolt->PCIe device - my reading of it is that it's just handling USB commands that the bridge is turning into separate PCIe commands to the GPU?
- gymbeaux 1mo agoMy 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.
- clhodapp 20d agoIt 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).
