Testing Results: Overclocking and Crossfire
Remember when I was talking about how great the Radeon Software was for customizing those clockspeeds? Unfortunately that didn’t translate into much for the RX 580. Aorus has pretty much gotten everything there is to get out of of it. While that is slightly disappointing, the RX 570 was a different story. There were some decent gains to be had on both the core and memory clocks. That’s mostly because the 570 is underclocked to be less competitive with the 580. Check out the validations below for the final, stable values.
Core temp and fan noise has come a long way since the R9 290. I ran out of power limits before I ran out of cooling potential on all of the cards I tested. I set some custom fan settings that targeted 70c and maxed at 80c. Below is the results of that. Temps and noise levels are great and while I could max fan speeds for the sake of maxing fan speeds, there is no practical reason to worry about it as an end user.
Time to put some performance on the overclocking results. There’s a lot of lines in that graph, but I can help clear up what’s happening. Essentially, we see some nice performance gains from the RX 570 and the GTX 1060. The RX 580 doesn’t fair so well. There’s virtually no performance gain in the title which gives little to no merit to push the card. The other interesting thing is how much the RX 570 closes the gap with the 580. We’ll come back to this in the conclusion.
So what advantage does Radeon have if they have trouble with overclocking? Turns out team red still kept an ace up their sleeve in the form of multi-GPU configurations. Nvidia decided to quit supporting SLI on their mid-range segment, a decision I hope they reverse in the future. Even then, Nvidia is very specific on how SLI will work, practically needing exact GPUs to support it. AMD on the other hand allows you to pair just about anything together as long as they have the same architecture. CrossfireX is the main reason I personally love AMD and combining the RX 500 cards together worked surprisingly well. As you can see, some situations won’t draw as much benefit, but boy did 1440p see some huge gains. Not bad!
