I believe the USB A port is only USB 3.1, and only the USB C port has Thunderbolt.
So the UD5 TH can support up to 12 thunderbolt devices and the Gaming 7 can only support 6 but uses the PCIe lanes for a second M.2 slot.
To compare the GT and Gaming 7, click the Add to Comparison List check box for one, click Compare Now, copy and paste to a text editor, then do the same for the other into a new window in the text editor, then do a compare. The GT has 2 op amps, 2 AGC switches, 2 BIOS switches, and the Gaming 7 only has one of each.
