On default settings, Radeon Pro 575 will go up to 95✬. That 20% more juice gives the card headroom for crunching very big scenes without FPS count impact. It gives enough juice, and is virtually silent during gameplay (on default settings).ĭifference between stock and overclocked 575 card in games is between being mostly at 60 FPS vs being glued at 60 FPS. That game has unusually dynamic scenes.īetween the three cards on 27" iMacs, I really do think that Radeon Pro 575 is the optimum one. Exception is CoD WW2, which stops being stuttery when run on overclocked card. Chances are you will need to focus to be able to note that. On default setting you will usually see 60 FPS, and occasionally, on very big scenes or with massive amount of effects, there will be some frame drops, but nothing major. That said, games run great on stock Radeon Pro 575. Even better than 5k, if yuou ask me, because stuff looks smooth, but crisp at the same time.) (I tout QuadHD here because stuff in that resolution look fanastic on iMac screen. Those with 570 will probably need to resort to playing on FullHD with Pro 570, or overclock to acchieve playable QuadHD.

Radeon Pro 570, 575 or 580 can run *anything* at all on that resolution with full details. If you can’t achieve constant 50-60 FPS mark, lower your resolution to FullHD. Not even Vega64 in iMac Pro would be able to run stuff at 5k with everything at ultra 60+ FPS.Īlso, mind that games that run below 50-60 FPS fall into playable, but not enjoyable category. Card that would be able to keep with 4k or 5k resolutions with all eye candy turned on needs to be at least +300% more powerful. The resolution to go for on any iMac 2017 27” is QuadHD + Vsync (if you don’t turn vsync, the screen will tear). I will pull analogy with lens here numbers acchieved in testing can trick you. In games, you won’t notice much difference. Unigine Superposition 4K optimized (default) score / FPS: Unigine Superposition 1920 Extreme (default setting) score / FPS: Unigine Heaven QHD, MAX settings, score / FPS: Unigine Heaven EXTREME (default setting), score / FPS: The speed comparisons are between normal clock and overclock (1300/2000), which proved almost completely stable. The performance gain achieved is about 20%, which is incredible, as that puts you in Radeon Pro 580 alley (3.8 GHz and 4.2 i7 models). Performance gains with overclock are astonishing, albeit with more noise and occasional instability. (That still doesn’t mean you can’t fry your card.)

Luckily both the card and the drivers have built-in stupidity protection, so they will stop the card if it get into dangerous zones. Rising voltage to max allowed enabled to me to run some test at 1400 MHz GPU clock, but the card crashed a lot. You can get higher, but you won’t be able to stay there, and there is a good chance that you will fry something. Increasing voltage or power limits doesn’t do much, because overclocks aren’t stable. Default clock for this card is 1069 / 1695. On my iMac 2017 3.5 with Radeon Pro 575, I achieved a stable 1300 MHz GPU clock and 2000 Memory clock. That won’t be too noisy, and will cool down the card better.

How to overclock Radeon Pro GPUs on 2017 iMac computers? MSI Afterburner is a graphic card overclocking tool, and Macs Fan Control is an app to control the fan speed of your Mac. Performance difference between Apple BootCamp drivers, and these reworked ones is significant. You will also need three programs to overclock your card:Ĭustom drivers are based on the latest AMD Radeon drivers, meaning they have the latest optimizations and fixes built into them.

You need to have Windows installed on your iMac. It should be noted that: OVERCLOCKING CAN FRY YOUR COMPUTER. Below you can read how I did it, what I achieved, metrics and some other stuff. Out of scientific curiosity, I tried (and succeeded) overclocking the Radeon Pro 575 on my iMac 2017 2.5 GHz 27”.
