    Hello,

    I'm back on a Mac Pro after 2 years, so I'm a bit out of the loop. From reading through the threads it seems the recommended GPU for a 2012 Mac Pro is the SAPPHIRE Pulse Radeon RX 580.

    Will it work out of the box? Do I need to buy anything else? Are there any compatibility issues? Etc..?

    Any help will be appreciated.
    Thanks.

    It should work out of the box with OS X 10.13. I'm waiting since two months for this card. How did you get it?

    I don't have it. Just checking I'm not going to have any issues.

    Are the pin connectors and power draw etc... all compatible with the Mac Pro?

    Cheers.

    In terms of driver support, it's OOTB.

    But power draw still under testing at this moment. It may draw more than 75W from the slot in extreme condition (exceed the official limit). But so far, seems didn't cause any real issue yet.

    I use one under OSX, and it's running like a champ! So far, so good. To connect it, you need a cable which adapts its 8-pin connection to dual mini-6-pin. You can find the cable on Amazon, for 13 USD.

    Has anyone put up Amazon Links to the power connectors necessary for this card and a 2010 Mac Pro?

    Ok, I just installed my Sapphire Pulse RX580 - but I do not get the boot screen, except for just a second or 2 right at the end, and it shows up as an R9 XXX. Is there more than one iteration of the Sapphire Pulse RX580? Mine has 2 HDMI, 2 DP and 1 DVI. Pics attached.

    You will not get the boot screen with an RX580, and the R9..... description is normal in Sierra.
    I believe in High Sierra it lists correctly, as its the card in Apple's eGpu.
    This is the same card I have in my mac.

    Ok, I incorrectly assumed that working OOTB meant that the card would have the boot screen. So that is my bad.

    OOTB meaning no setup, no drivers required..... unfortunately no boot screen :)
    But, really is it required?
    One thing I recently discovered, is to upgrade to HS, you need an Apple EFI card to perform a firmware update.
    Luckily I still have my old card.

    I'm going to run a few Benchmarks to see if it's worth it to ditch the R9280x, and go to the RX580. What should I run aside from Geekbench.

    Sorry thats out of my expertise, I don't dabble with benchmarks/speeds etc, just plug it in and use it.
    Have a look at the other threads, these benchmarks have all been done by others.

    with the RX580

    Geekbench: 26817
    Cinebench 59.57 fps

    BruceX: 38 Seconds

    Unless if someone can make sense of this for me and tell me something I don't know - I'm not sure the RX580 is all that much better than the R9280x.

    CineBench and Geekbench is benchmarking the CPU, not GPU. If you want to see why upgrade to RX580, try some real OpenGL benchmark (e.g. Unigine Valley, or Unigine Heaven, etc).

    Anyway, Luxmark 3 should be a good OpenCL benchmark.

    Another benefit, and to me the primary benefit, is that you can now run 4K and 5K displays (in theory) due to the RX580 having the more modern DisplayPort 1.4 and HDMI2.0 standards.

    Yep, as someone else has pointed out, you would need High Sierra to have the correct name shown.
    Indeed the drivers in High Sierra will likely be more up to date and probably perform better than the RX580 driver in Sierra.

    Could not find the dual 6 pin ones on ebay :(

    I suggest you read the thread before posting, just a common courtesy to other users.

    The RX 580 should be running 19-20 seconds on bruceX. 38 seconds seems a bit high.
