Not quite. USB4 is based on TB3, but interoperability with Thunderbolt 3 is optional for hosts and devices. You could use any TB4 dock and USB4 dock that have USB4 upstream ports.

40gbps, 20 gbps (in 3.2 mode), PCI-E are all optional for host.

It's a mess, but I assume "fully capable USB4 ports" means that they are indeed fully capable. 2 "full" USB4 ports imo enough. I'm not plugging 4 monitors into my laptop directly, that's what the dock is for.

That's what I meant by "full" USB4... in that you get TB compatibility and higher speed... One third port on one side also has displayport mode over usb or can use an hdmi adapter on that port. Only 1 isn't capable of display out, and 2 are capable of high speed connections (external gpu or dock).

In the end, I do think the connectivity, while less than the Intel option, is probably enough for most people for most uses. I honestly don't use my personal laptop much and my work laptop is pretty much always docked to my TB3 dock at my work desk.
