Note that you can do point-to-point network links directly with thunderbolt (and usb4).<p><a href="https://support.apple.com/guide/mac-help/ip-thunderbolt-connect-mac-computers-mchld53dd2f5/mac" rel="nofollow">https://support.apple.com/guide/mac-help/ip-thunderbolt-conn...</a> etc

Thunderbolt is basically external PCIe, so this is not so surprising. High speed NICs do consume a relatively large amount of power. I have a feeling I've seen that logo on the board before.

Neat, but the thermal design is absolutely terrible. Sticking that heatsink inside the aluminum case without any air circulation is awful.

Now I just have to contrive the circumstances where this is useful to me. :)
