I've been looking through the new AMD X570 motherboards and it seems that only the Asrock Motherboards support Thunderbolt 3 either directly or through an expansion card. I know that Thunderbolt is an Intel system, which means it needs to be licensed, but I find it kind of strange that only Asrock is supporting Thunderbolt 3 and not the other main manufacturers like Asus, MSI, Gigabyte.
Unless I'm missing something of course.
