    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).

        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).

          K then buddy. Keep buying dongles for your dongles.

          My point is that including the ports is extremely simple. I’m not telling you that it’s wrong to choose to use a dock because you find it more convenient. I’m just saying that you could have the option instead of that being the only option you have. There’s no technical reason to not include the actual physical separate ports.

          Also, monitors and your earbuds? That’s a very low bar. Lots of different tasks would require far more than that. Devices should be flexible.

            Devices should be flexible.

            Agreed. It’s a pity, then, that no-one has invented a single port that can replace USB-A, DisplayPort, HDMI, propriatary power connectors, Thunderb… oh… wait…

              Yeah, show me a laptop that has 10 of those. Plus, your conveniently ignoring the plethora of adapters you’d have to use if all you had were USB-C ports.

        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.

          So, barely a handful? Great. How much do they cost? And how much does it cost to just use the cable your devices come with?

            The countless remaining docks support Thunderbolt 4, which at 40 Gb/s is still twice as fast as USB-C 3.2 Gen 2x2.

            They range from $49-$299, depending on the features and number of ports needed. If you’re using the native HDMI port on your MacBook Pro, it’ll be on the low end of the price range.

            The only cable that comes with a MacBook Pro is a USB-C charging cable.

              Awesome. But what I think is ideal is having multiple ports which, in addition, would give you more bandwith, more reliability and more flexibility than a single high bandwidth hub.

              The only cable that comes with a MacBook Pro is a USB-C charging cable.

              You misread. I was referring to the cables the devices you use with your laptop come with.

                MacBook Pro comes with three Thunderbolt 5/USB-C ports (120 Gb/s), HDMI 2.1b, MagSafe 3, and a 3.5 mm headphone jack. Trading a USB-C port for USB-A means potentially downgrading a USB-C capable device to USB-A with an adapter. The opposite results in better performance, and the adapters will continue to be useful as long as you own USB-A devices. When computers only have USB-C ports, your other adapters will be useless.

                As for cables, I replace them rather than using adapters. Monoprice.com sells quality cables relatively inexpensively.

                  Again, missing the point. There’s nothing you need to “trade”. They could simply add more ports.

                  Monoprice is not a worlwide brand and buying more stuff is not a sensible solution to a manufactured problem.

                    There’s nothing simple about adding more ports on a portable computer. It means additional buses, I/O boards, and a larger device size.

                    Most manufacturers that offer USB-A ports don’t have three Thunderbolt 5 ports. It would either be modular or a trade if you’re making a true comparison.
