I checked my thunderbolt system data and i see that the speed on the gaming box is 20gb/s x2, from what i read it should read 40gb/s x 1. I am using the gaming box 0.5 cable connected to the top left port. Any thoughts.

@tsakal Most of your questions and concerns have already been answered elsewhere. Please search through the forum for answers. Smile

No, there is no throttling going on. 

Charging is not a factor in performance.

I hope you had a nice thanksgiving. 
I have tried all recommendations from the forum including reinstalling the macOS and updating the gigabyte firmware. However the way the mbp is connected to the gaming box still is the same like above 

Status: Device connected

  Link Status: 0x2 / 0x1

  Speed: Up to 20Gb/s x2

  Current Link Width: 0x1

  Link Controller Firmware Version: 0.36.0

If everything was good is should read status 0x2, speed 40 x 1 and width 0x2. Do you agree?  Is there a way to check whether there are any leftovers from the patch i was using before? Unless there is a problem with the tb3 of the gaming box

Performance wise cinebench should be around 72 vs 60 that I get based on other people using the a mbp with a gaming box. I have access to a dell XPS 13 how can I check whether the tb3 is functioning correctly?  Is there some software to do that as I am not very familiar with windows.

thank you in advance

@tsakal Can you download and run CL!ing on the eGPU? Here's an example of what the correct bandwidth in CL!ng would look like.

Those numbers showed the Thunderbolt 3 connection is limited to 20Gb/s. The firmware on RX 580 Gaming Box is good because H2D would have showed 1,1XX MiB/s otherwise. I'd recommend contacting Apple Support to have your 2018 MacBook Pro looked at.

@tsakal What about trying a different TB cable? Might help. Hope you had a great thanksgiving yourself Smile

purge-wrangler patches cannot affect TB-link speed regardless of their presence. Also, if the script says there's nothing to uninstall then it's impossible for anything to have been left-over.

Like @mac_editor stated this bandwidth limitation is not due to software. Some where in your setup, a hardware component is not working properly. The Thunderbolt 3 cable is the easiest one to swap out and see if there's a difference.
