TB3 is 40Gbps, USB-C 3.2 10Gbps. 4K@60Hz is possible over USB-C but 4K@120+Hz only with TB3 AFAIK (or dedicated DP cable of course).

- kllrnohj 6y agoThe 40Gbps is for the data connection of TB3. The display part of TB3 is independent and is just DisplayPort. Both TB3 and USB-C alt-mode can do DisplayPort 1.4, assuming both sides support it of course. TB3 only actually requires DisplayPort 1.2. There's actually no difference here whatsoever on the display-only side of things. (side note, USB 3.2 achieves up to 20Gb/s, not 10Gb/s, and TB3 is also realistically only 20Gb/s as well unless you're sticking to the super short 0.5m cables)
- distances 6y agoRight, I was thinking of USB 3.1 Gen 2 which is 10Gpbs. Hooray for these naming schemes. But good to know about the display connection being the same. I was under the assumption that the increased data rate of TB3 could be used for DisplayPort connection too.
