[SOLVED] Can you solve the Thunderbolt AIC compatibility mystery?

[dovedescent7]

Just switched from Intel to AMD after 20+ years. I just purchased the Ryzen 3700x + Gigabyte B550 Aorus Pro


I want to add the LEAST EXPENSIVE Thunderbolt 3 AIC add in card since my mobo has a thunderbolt 3 header on the board. Considering GB Alpine Ridge THIS CARD

My questions are general to TB3 AND specific to my board.

1. Do i need to run a Displayport cable if I am not using the TB3 card for display? I'm only using the card for file transfer.. And What's the purpose of connecting the TB3 card to a GPU via DP?

2. Which cards will work with AMD B550? And i don't ask what is "supported" because(at least for intel): the Asus tb3 1st Gen AIC said it only supports x99 on Asus mobos but ACTUALLY works on z370 and more, w/other brands boards. There's a few other situation's just like this with other brands of TB3 AIC's.

Answer to question 1
connect the Mini DisplayPort input if you wish to use a Thunderbolt 3 monitor. Otherwise it's not necessary.
