Cheers for this Pharm,

I have a simular setup 13" 2020 i7 MBP 32gb Core X Chroma +Sapphire Pulse RX5700XT.

I will not be trying Windoze just yet but not getting the full benefit from the card using FCPX its only giving me 35-40%

I have a 7" 4k monitor and mirrored the displays, the monitor I intend to use is out of stock here.

I have heard about using a headless HDMI plug to increase the graphics speed, are you aware of that?

Cheers Zeb

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

@zeb, hi, I am adding also @andygev35 and @itsage if they can offer any insight. 

I have a similar setup but I feel my cpu is not performing as expected 

For example my cpu never runs above 3.6 ghz even in 2 thread test. For comparison my 2018 i7 model runs the same test at 4.4ghz. 

In 5 thread test the 2020 model runs at 3.2ghz while my 2018 is more 3.5ghz

I would appreciate you response as I am deciding whether to keep it or send it back. 

Can you share some data from a cinebench r20 test ? 

Full 8 threads score and av frequency 

5 threads average frequency power draw watts and temps 

2 threads av frequency power draw

@zeb 

After talking to apple support and getting my performance logs today they came back with their verdict. 

Apparently there is a firmware bug affecting the t2 chip introduced with the 10.15.6 update which is the reason for my 2020 mbp i7 underperformance. Supposedly will be fixed in the next update.
