4k60 + gigabit is not possible without going up to Thunderbolt 3 - there isn't enough bandwidth otherwise. The best you can do is 4k60 + USB 2.0 (so a gigabit Ethernet connection would cap out at ~300mbps in practice.) See https://www.bigmessowires.com/2019/05/19/explaining-4k-60hz-video-through-usb-c-hub/ https://www.bigmessowires.com/2019/05/19/explaining-4k-60hz-...
DisplayPort 1.4 changes this, but everything seems to be stuck on 1.2
100W is, of course, possible.
I use a CalDigit USB-C Pro Dock with my MBP: https://www.amazon.com/gp/aw/d/B07VL675DT https://www.amazon.com/gp/aw/d/B07VL675DT - it's TB3, but it can fall back to USC-C (with reduced capabilities, of course). It uses Intel's newer Titan Ridge chipset. The older and more common Alpine Ridge chipset is TB3 only.
- tn890 7y agoHow does the CalDigit TS3 Plus do it then? Too bad about the 85W.
- nfriedly 7y agoIt uses Thunderbolt 3. Same connector, but different protocol with 2-4x the bandwidth.
- tn890 7y agoI fail to see why you assumed I wouldn't want a thunderbolt 3 dock.
- nfriedly 7y agoBecause you said "preferably through USB-C".
- tn890 7y agoI meant the actual physical connection? Man this whole Type C thing is confusing. Wasn't it supposed to simplify USB?
- nfriedly 7y agoOh, I see. Sorry about that. This stuff is stupidly confusing. For what it's worth, unless you're doing a constant full load on your CPU and GPU, 85 watts is probably enough.
- crooked-v 7y agoThunderbolt 3 is the same form factor as USB-C, but there's different hardware in the cables themselves to enable higher data throughput. If you want to use Thunderbolt 3, the devices on either end need to specifically support it. Note that in the future, Thunderbolt 3 is getting de facto rebranded as USB4 (no space). https://arstechnica.com/gadgets/2019/09/usb4-is-coming-soon-and-will-mostly-unify-usb-and-thunderbolt/ https://arstechnica.com/gadgets/2019/09/usb4-is-coming-soon-...
- gambiting 7y ago>>100W is, of course, possible. I don't think it is. The dock itself uses quite a lot of power, that's why the highest you can find is about 85-90W. USB-C cables support max of 100W so I don't think it's physically possible to accept 100W and output 100W at the same time.
- nfriedly 7y agoWell, with these power pass-through hubs like what the website has, you're correct. I was thinking more of a proper dock that has its own power supply. My dock has a 150W power brick, and then it supplies 85W to my laptop. In theory, the numbers could be 165W and 100W.
