This is my first eGPU setup and post here!!!  Thank you all for the awesome resource, especially goalque!

 

System specs

  • iMac 27-Inch "Core i7" 3.5 (Late 2013) (Nvidia GTX780M + Intel Iris Pro 1536 MB)
  • OWC Helios TB3 with NVMe PCIe card with Samsung SSD PRO 512GB connected via TB1 (internal Fusion Drive has failed)
  • macOS Catalina 10.15.3

 

eGPU hardware

 

Installation steps (what did you do to get it all going?)

I just got the setup working this afternoon. I also tested the same eGPU setup connected to my 2018 MBP 15'' (6C, i7, Radeon Pro 560X). Had to disable secure boot options to make that work, but otherwise worked with no apparently problems. the eGPU is roughly 7x faster than the iMac's NVIDIA GTX780M and 3x faster than the MBP's dGPU. Plan to try an Ubuntu Linux boot on the iMac using another USB drive with the eGPU to see if I can get it to work. Might invest in a mightier NVIDIA card in the future for some ML work if I can get the Ubuntu Linux boot to work.

Current Build:
27" iMac (late 2013) + XFX Radeon RX580 8GB + ASUS XG Station Pro + automate-eGPU EFI v1.0.5 + OSX 10.15.3

Hi, did you had to used external display for that setup or you used internal iMac display ?
I'm about to try egpu on my late 2013 27" iMac but used it without external display.

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

Thanks for sharing your build! Have you tried Boot Camp at all on the iMac?
