@fanoftech4life I haven’t seen your question about USB-C vs. TB3 bandwidth answered, so I’ll have a go at it in the expansion thing here.
USB Type-C vs. Thunderbolt-3
The USB-C spec is kindof all over the place depending on the version used and even the implementation, as some capabilities can be left out such as PowerDelivery, but in its ultimate (and imho very rare) v3.2 spec can carry 20Gbps (20 gigabit/sec or about 2.5 gigabyte/sec) of bandwidth. TB3 does 40Gbps.
For me, currently using a Dell laptop with TB3 and using a pretty decent TrippLite type-C Dock with both miniDisplayPort and HDMI. Using it in the office where we just got new 4k displays - due to the bandwidth requirements of that, I can’t get 4k60 out of it which is just frustrating as hell. I hate having choppy laggy mouse and window movements with 4k30. I use mDP on it but it seems superfluous since it does the same thing as the HDMI port so the most I can practically get out of it is 4k30.
My answers to this discussion - apologies for the length but I am passionate about this!:
What’s the biggest painpoint(s)/problem(s) it resolves?
For me, a middleweight dock should be a one-cable solution, eliminating cables all over the place, keeping my desk neat and providing a place to plug in more permanent things like hard drives, dongles/KB’s/mice, audio devices and of course displays.
Must have features for me:
Above all else: TB3 - for the greatest versatility, from eGPU to multiple hi-res displays
Second: Power Delivery (I already purchased an Apple 80-whatever-watt Type-C charger as a home charger so I’m happy if it comes with its own supply, or not)
Third: non-captive main connection cable (meaning I’m not limited to a worthless 3-inch TB3 cable that will inevitably get bent, pulled and abused)
How it is better than the existing products?
It will support the latest specs, maybe even future ones if at all possible. It will also contain enough and varied ports to be useful to most people. Just by having TB3, USB-PD and a good selection of ports, it’s already in the top 5 of docks available. “All we need to do” ;] is argue over ports, cooling, then get it compact enough so it’s not a Dell TB16 hehehe
In the market, the following product(s) is my favorite
Dell TB16 is nice, just big, v.expensive and apparently loud from its cooling fan
Aforementioned TrippLite dock is great because of the port selection, USB-PD and its portability, but lacks in bandwidth, gets almost too hot to touch in average operation (4k30 all the time?) and has a terribly short built-in cable.
The OWC 13-port dock is pretty good but a little overkill considering optical and fw800.
And if it is improved as above, I would like to pay $___
to buy it immediately
I’d easily do $150, then possibly up to $250 if it was absolutely amazing.
As an aside, I wonder about the lack of support from Intel if sales are below 10k units. Is support from Intel absolutely required to make a TB3 product?
