    Wasn't meaningless as I learned much by starting with this test. Failure or not, it gave me something to build on. Everything depends on what you want with a test.

    Of course we can always learn something by doing almost anything. However, from your original post, what you want to know is the performance of RX580 vs GTX970. And you said the test results mean something (RX580 is way slower than GTX970), but it is not.

    They can be meaningful to you because you learn something. However, it shows nothing about RX580 vs GTX970.

    It can’t show how MacOS vs Windows because the hardware is different.

    It can’t show how RX580 vs GTX970 becasue the OS is different.

    It can’t even show how RX580 in MacOS vs GTX970 in Windows because even the API is different.

    Sorry for my poor English about using the confused word “meaningful”. My comment was actually referring to your original post about the test result is some kind “valid” (for 580 vs 970), but it is not.

    If you are primarily using Premiere Pro CC, I would personally go for the 980Ti, even though both the 980Ti and the RX 580 perform well in Premiere, but openGL on Premiere is a lot faster than the RX 580 and openCL

    What I meant by valid was that it made me realize lots of stuff. Not valid in the meaning that we now have certain knowledge about 580 vs 970. One thing I learned is that you get false answers if you compare GPU:s with different modes (open gl vs direct). I'm very new to these kind of tests, so exscuse me if I'm using a bad and confusing vocabulary.


    Anyway, it's fun to learn more about the cMP hardwares. So I'm very glad you all take your time explaining and discussing this.

    Ok, thanks for telling! And this is when you're running macOS?

    Thanks for the info (even though it was not aimed at me directly)!
    I've been tempted to get a RX580 for (hopefully) better OS drivers, but the more I read about it, the more I think I should stick to my GTX980Ti - I don't do FCPX, little Premiere, some Resolve (tried a 1080 but was disappointed by the performance, almost identical to the 980) and mainly Avid which doesn't care about GPU (though the GTX not-so-great-drivers don't make a great combo with this app).

    Yes, under macOS. it may be even faster in Windows, but i'm not sure.

    After 3 months I finally received my Sapphire RX580 Nitro+ 8 GB today :) and it works OOTB.

    macOS only has a record of one vendor ID model so it won’t present the name for cards from other vendors.

    When you install a device in Windows it checks against a global registery online and then downloads, installs a driver and correct device name. Apple needs to catch up with the 90s.

    You're not supposed to install a 3rd party GPU on a Mac, so Apple won't bother.

    I just bought a Sapphire RX 580. I would like to keep my current AMD 5770 in another PCI-E slot for boot screen. Could someone recommend the proper and how many power cables that I need to buy for this setup? Thanks.

    2 cables required

    1) dual mini 6pin -> single 8 pin

    2) single 8pin female -> dual 6+2pin

    Then one of the 6+2 can power the 5770. The other one power the RX580. No matter which card under stress, all loading will be shared by both mini 6pin.

    The single 8pin can be replaced by single 6pin, doesn't really matter. In both case, all pin 1,2,3 can supply 12V power anyway. The single 8pin (or 6pin) is just a bridge for loading sharing. But in general, dual mini 6pin -> single 8pin is a more useful cable (as per the point below).

    Technically, the female port can be on cable 1 or 2, doesn't really matter. However, recommend female connector on cable 2. Therefore, cable 1 can be used solely if you only run the RX580 later.

    Ok cool. Do you have any recommendations on Amazon for those two?

    Perfect! 100% correct.

    I usually get the cheap cables from China. So don’t know which one on Amazon is good.

    DO NOT get the "gutsParker" Dual 6 to 8 pin adapter! Mine broke after one day!

    Some years after first considering a GPU upgrade (and a couple of failed eBay buys) I've just got an Aorus RX580. The mining craze price increases have finally gone, yay! Will be installing it this weekend, along with the nVidia GT120 I bought ages ago for boot screen. Quick question: am I OK to plug both cards into the monitor and just switch inputs or is it better to switch cables?

    I believe either or works, but just switching cables would make more sense.

    Switch input is easier. HOWEVER, you may need the disable monitor script. Otherwise, technically your Mac will sense you have 2 monitors. Therefore, no matter which input you choose, you can alway only see one monitor. That means, you better run the dual display in mirror mode. Otherwise, your mouse pointer / windows may accidentally go into another desktop. But I don't know if there is any performance degradation if you run them in mirror mode since the GT120 is much much slower than the RX580. I was with dual 7950, mirror mode is fine because they have identical performance.

    Hello. Can someone share a a test of double (dual) rx 580 in Final Cut Pro x Bruce x?

    I’m thinking in going dual. (Already have a ASUS strix rx 580 8gb)
    My main use is FCPX.
    So I wanna see if there is real benefits of this or it’s only to brag


    Thanks!

    So I bought this dual mini 6pin -> single 8 pin:
    https://www.amazon.com/gp/product/B0749DQ3VX/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1

    And this single 8pin female -> dual 6+2pin:
    https://www.amazon.com/gp/product/B0753DTX1N/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1

    The single 8pin female -> dual 6+2pin cable I bought seems to be the wrong type of female cable because it will not fit the male end of the dual mini 6pin -> single 8 pin. Do you have another recommendation of one that will fit it? I'm having difficulty finding one that will.

    RX 580 prices have gone down. But, I don't think it's down enough. Cheapest 8GB RX 580 at Newegg is $279.99 for a PowerColor version.

    According to this graph that is a screenshot from an Anandtech article of RX580/570 launch review, the MSRP for RX 580 8GB is $229.

    Screen Shot 2017-10-20 at 2.58.20 PM.jpg

    So, a PowerColor RX 580 8GB for $280 is still $50 above original MSRP.

    But, I'm a realist, so I figure that in the normal world, RX 580 8GB should be around $240. And, $260-$280 for the super overclocked, fancy cooler OC AIB ones, which aren't the ones Mac Pro users want because we just want the Reference single 8-Pin ones....

    The picture looks correct to me, why it doesn't fit?
