You all asked for it, and now I’ve got the results. This is taking the same run of benchmarks as in our previous RX 480 vs GTX 1060 in DX12 and Vulkan and applying a healthy overclock to both cards. If you wanted information on our testing methodology I recommend reading over the previous article linked HERE for that information. We’ll be keeping the writing in this one on topic in regards to the overclocking and results.

XFX Radeon RX 480 OC

Starting off with overclocking the RX 480 we utilized wattman. Following the included guide for increasing efficiency can also be used to overclock the RX 480. We settled on a stable core clock of 1350Mhz and a memory offset of +225Mhz. To get there we did have to boost the voltage to 1150mv and the power limit to +50%. I did have to set a custom fan curve to maintain this overclock but we still reached a toasty 89c at a few points with the fan screaming at nearly 4k RPM.

NVIDIA GeForce GTX 1060 Founders Edition

Overclocking the GTX 1060 was admittedly an easier affair, but still required a voltage bump of 50% on the EVGA Precision X OC slider. Doing so allowed for us to push the core clock +225Mhz resulting in a peak overclock of 2126Mhz, but settling at 2088-2101 when under load. The memory could have gone +700Mhhz, but exhibited a bit of instability, so was backed to +500, resulting in the same effective memory clock rate of the RX 480. We’ve included our guide for overclocking the GTX 1060 using EVGA’s Precision X OC. Leaving the fan curve at its stock curve we reached a peak temperature of 78c with the fan only getting up to just over 2k RPM.

Ashes of the Singularity

Ashes of the Singularity has possibly been the longest go-to DX12 benchmark, mostly because it was one of the first. Most benchmark results you see floating use the “Crazy” preset for this game, but we’re using the “High” as we feel it’s fairly representative of what you would be running this game at if you owned one of these cards.

DOOM

DOOM, the first non-beta example of the Vulkan API running with full Asynchronous Compute support. We did make sure we ran this game with the settings that would take full advantage of this feature. One think I will say about this game is it really shows that you don’t have to use Direct X if you want to make a beautiful game.

 

 

Forza Motorsports 6 Apex

Apex has to be the first title to come out of the Windows Store using the UWP that didn’t perform like a sack of rotten potatoes on day one. This has been a title that has enjoyed very good performance across the board since day one. The hardest part of benchmarking this game was stopping and not continuing to the next lap!

 

Gears of War: Ultimate Edition

Remember what I said about performing like a sack of rotten potatoes, this is the game I was referring to. The Windows Store first big DX12 launch was an absolute disaster performance wise at launch. I’m happy to report that all of that is no longer the case, even though the game has swelled to over 50GB in size.

 

 

HITMAN

HITMAN 2016 is the latest in the series and is being released as an episodic adventure. This approach feels natural with this game, however with each update they tend to toss in performance ‘upgrades’ as well. Because of this the game needs to be retested regularly.

 

Rise of the Tomb Raider

RotTR had pretty bad performance when it first rolled out the DX12 patch. Thankfully that has changed significantly and has even released a recent update that allows for Async Compute capability.

 

Total War: Warhammer

If there’s any game series in history that could benefit from DX12 it’s this one. Total War has been a notoriously single threaded game in the past making it pretty much perform the same regardless of what high end GPU you have once the screen is full of units.

 

 

Conclusion

While I don’t recommend overclocking on the reference RX 480, these results show promise for the aftermarket RX 480s as this OC is just a hair faster than what they’re shipping at. It also shows that overclocking the GTX 1060 helps it out quite a bit in DX12 and Vulkan. There really isn’t a whole lot more to say at the end of this, both cards benefit a fair bit from overclocking and it doesn’t take much effort to reach these levels for the gain.
