    My upcoming computer setup is going to be something like this:
    late 2018 Mac Mini
    eGPU(Thunderbolt 3)
    HDMI 4K monitor
    I've read this: https://kb.parallels.com/124266
    It says:
    What if the display is non-Thunderbolt and plugs in via HDMI instead, does that means the display can't take advantage of eGPU?

    To clarify my question, how straightforward is eGPU with Parallels 15? Can I have macOS use the integrated graphics while assigning the eGPU to Windows 10?

    @AlexA2, you need to connect the eGPU to your Mac, and only when it works fine in macOS, Parallels Desktop will use the available graphics resources to increase virtual machine video performance.
    Also it is not possible to connect an eGPU device directly to VM.
    Please check this KB article for more info and let us know if it's not that case.

    Another question - how good is the graphics performance for the newest 5K iMac with Radeon Pro Vega 48 with 8GB of HBM2 memory? Can a VM be configured to get most of that RAM, like 2GB for macOS & 6GB for Windows?

    Egpu works fine with Parallels. It isn't treated as a stand alone device in the device manager, it's just treated as the default display adapter.

    I use a Mac mini 2018 with an external Vega 64 with the 4K screen connected to the Vega 64 HDMI port. Works fine. I don't use the Mac mini hdmi port.
