    USB-C is just a connector, but Thunderbolt 5 uses it and for asymmetric uses (e.g. a monitor) it can hit 120Gbps.

    Isn’t that going to support most monitors?

      Please, list the devices that you know have tb5.

      Also, that’s the total bandwidth in a best case scenario. You’re not factoring in that you’ll need to share that with all of the devices in a hub. That’s without mentioning that you need the hub (which also has a cost).

        All high quality peripheral docks support Thunderbolt. Thunderbolt 5 docks began to release last month. You can connect the devices to the dock using USB-C, then just use one Thunderbolt cable to connect the dock to your Mac to prevent a bottleneck.

        The USB4 protocol can handle 160Gb/s split asymettrically (so, say, 120Gb/s out, 40Gb/s in), wheras the upper limit for DisplayPort’s highest bandwidth mode, Quad UHBR 20, is 80Gb/s in one direction. So you can saturate your DisplayPort 2.0 quad-channel with more than enough bandwidth to power three 10K 60Hz 30-bit (i.e. very high-end) monitors in DSC mode, and still only be using half the bandwidth of USB4, all using a single cable which I can also use to charge my earphones.

          Most devices only have 40gbps USB4. Which is still enough for almost all sane use cases. Frankly, if you need multiple 4K monitors get a desktop.

            Uhm no? There are more than a few use cases that require a mobile set up for demos for example but that you’d also want to use in a desk setting. For example, architects or sw dev.

            Which is still enough for almost all sane use cases.

            Like 2 4k60 monitors and literally nothing else? You have a very conservative opinion of what a “sane” use case is. Not to mention that lots of USB-C cable certification is a mess so not even getting the cable is simple (or cheap).
