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.
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.
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.
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.

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.
The 2017 model pictured in this post supported Thunderbolt 3, which was a 40 gbps connection. Supported display modes included up to 4k@120, 2x4k@60, or 5k@60, which was better than the then-standard HDMI 2.0.
What combination of resolution, frame rate, and color depth are you envisioning that having a dock handle a gigabit Ethernet connection, analog audio would require scaling down the display resolution through the same port?
Even if we talk about DisplayPort Alt Mode, a VESA standard developed in 2014, and supported in the 2017 models pictured in this post, that’s just a standard DP connection, which in 2017 supported HDR 5k@60. But didn’t support a whole separate dock with networking and USB ports.
Supported display modes included up to 4k@120, 2x4k@60, or 5k@60
Right, for a single device.
What combination of resolution, frame rate, and color depth are you envisioning that having a dock handle a gigabit Ethernet connection, analog audio would require scaling down the display resolution through the same port?
Dual 4k120 would already saturate the bandwith. Regarding networking, gigabit is pretty slow for LAN depending on your workload. If you were to require 10gbit, you’d be SOL.
By 2021, the MacBook Pros were supporting TB4, and the spec sheets on third party docking stations were supporting 8k resolutions, even if Macs themselves only supported 6k, or up to 4x4k.
Did you read the specs in your link? Even with that TB4 dock you wouldn’t be able to do dual 4k120.
I really don’t get trying to justify manufacturers forcing you to buy an additional device to get the same ports they could provide natively without using a hub/dock. It’s a pretty submissive attitude.
You can only do that because your monitors are not high resolution and high refresh rate. The data cap for usb-c is not that high.
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.

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.

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?

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.
Every enterprise laptop I’ve seen in the last 5 years?
Sorry but you’re full of crap. The first TB5 laptop was released this year and I’m not sure there are more than a handful of models.
You’re welcome to prove me wrong though.
Can you break this down?
