Hello. I apologize if this has been asked but I was trying to search for the answer all night and couldn’t find it

I have the 2020 13” Macbook Pro and an LG UltraFine 5K. It seems there is no great solution as far as plugging the 5K monitor (with only a Thunderbolt 3 input) directly into an eGPU and still get 5K resolution aside from getting a BlackMagic eGPU

What I am thinking of doing is plug the monitor into 1 TB3 port and the eGPU on another ON THE SAME SIDE of the laptop. 

I have a couple of questions:

1. What kind of performance loss should I expect?

2. Does it matter which side of the laptop I plug it into?

3. Even with the performance loss, will I still get better performance with a 5700XT compared to the Radeon Pro 580 inside the BlackMagic?

To do: Create my signature with system and expected eGPU configuration information to give context to my posts. I have no builds.

It's really quite a design flaw that they didn't put a DisplayPort port on that monitor with DSC enabled to get the full 5K resolution
If they did I would've purchased one a long time ago

Also the fact that BlackMagic doesn't even make the higher end "Pro" eGPU anymore, combined with the fact that eGPUs aren't supported at all on the new M1 Macs, makes me really facepalm hard

As to your question -- I'm guessing you have the MacBookPro 16,2?

Performance will depend on the app you're using, if you're doing DaVinci Resolve for example, it will actually be capable of using both of those GPUs at the same time, which is pretty cool.
