Tf is USB4 PCIE tunneling and how to i use it?
The laptop allows you to enable PCIe tunneling on your USB 4 port via BIOS settings. This feature is typically used for connecting external GPUs or other peripherals. However, it's unlikely to work with a standard GPU directly unless it's specifically designed for that purpose. You may need an adapter or a compatible card to achieve this connection. To find an adaptor, check online retailers or specialized electronics stores that sell PCIe expansion cards or USB-to-GPU converters.
I don't have enough information to identify the specific laptop model. Could you provide more details or the name of the device?
Do you know when USB4 eGPUs will start coming to market? Since USB is an open standard, it should cost only a small portion of the price for Thunderbolt 3/4.
I’m trying to replicate what Linus does. I don’t have it in another space, but my caldigit ts3+ dock is all connected. I plug the Thunderbolt cable into the motherboard with the GPU hooked up for passthrough. It doesn’t work—I see the dock showing up and some peripherals, but when I connect just the dock, no video comes through. Can anyone suggest how Linus achieved this? Thanks!
It’s worth noting these points:
1) All USB 4 ports with PCIe support work technically.
2) Activation in BIOS might be required.
3) Even after activation, the PCIe lane may not link directly to the CPU, just the chipset.
So your concern about using an AMD laptop for eGPU is valid—especially if you’re not dealing with proprietary setups like certain ROG models.
