Question Radeon WX7100 eGPU connectivity with 2018 Macbook Pro

Mar 5, 2019
I am looking an external GPU to use with my Macbook Pro 2018 to more effectively push a 1440p monitor with 10bit color for more intensive video and photo editing. From my research it seem that only the Radeon Pro and Quadro workstation cards are the only GPUs which actually are capable of pushing 10bit color. Just because of cost im likely going to go with AMD. However it seem all of AMD's Radeon Pro series cards only have DisplayPort outputs and to my knowledge eGPUs only work with modern laptops over Thunderbolt 3. Is it possible to connect an eGPU to a laptop over a DisplayPort to Thunderbolt 3 converter. Thanks!
