    Or because nobody is paying $1500 on a card to stick in their computer.

    Tempting, but the power draw is YUGE

    May be better off w/ multiple RX 480s for OpenCL compute.

    I'm testing dual RX 480 working w/ D700s on nMP.
    Super excited by the potential to run 128 compute units off a 12-core for an 8K narrative film post project.
    (for OpenCL compute performance the 2GByte/sec bandwidth on TB2 has a 0~3% reduction vs TB3)

    Won't work. Get two R9 Fury X and run them with an external PSU.

    Was your note in reply to my post or in general to the thread?
    Thanks

    It was in general. macOS doesn't recognize GPU with dual chip setup. 2 R9 Fury X GPUs is the equivalent to the Pro Duo and will work as long as you can supply enough juice.

    Thanks for clarifying.

    While the automate-eGPU.sh script Goalque updated a few days ago does appear to provide full access to all 36 compute units on the RX 480, I suspect we'll see better performance when 10.12.4 is released w/ native Ellesmere support vs running Polaris 10 using the Polaris 11(Baffin) drivers currently baked into macOS.
