Makes sense. Instead of a symmetric 80 up/80 down, it's an asymmetric 120 up/40 down, using 3/4 lanes for upstream to devices. The use case is displays; people

Makes sense. Instead of a symmetric 80 up/80 down, it's an asymmetric 120 up/40 down, using 3/4 lanes for upstream to devices. The use case is displays; people want to plug in a lot of monitors, which are very high bandwidth devices. Im going out on a limb & guessing it's upstream only, that if you've got a bunch of video capture devices you dont get 120Gbps in.
