Sapphire Dual-X R9 285 OC Review

Game Benchmark Results Continued

Metro: Last Light

“It Is the Year 2034. Beneath the ruins of post-apocalyptic Moscow, in the tunnels of the Metro, the remnants of mankind are besieged by deadly threats from outside – and within. Mutants stalk the catacombs beneath the desolate surface, and hunt a midst the poisoned skies above.”

Developed by 4A games and published by Deepsilver, Metro: Last Light uses the 4A game engine. At it’s highest settings, the 4A game engine is capable of bringing all but the most extreme gaming systems to their knees.


“Garrett, the Master Thief, steps out of the shadows into the City. In this treacherous place, where the Baron’s Watch spreads a rising tide of fear and oppression, his skills are the only things he can trust. Even the most cautious citizens and their best-guarded possessions are not safe from his reach.”

Thief was developed by Eidos-Montréal and published by SQUARE ENIX, Eidos Interactive. The newest game in our benchmark suite, Thief is also one of the most demanding and has the highest recommended system requirements. Those heavy requirements allow it to use the Unreal 3 game engine to great effect. It also features AMD’s Mantle API, as well as Microsoft’s common DirectX 11 API.

Tomb Raider

“Tomb Raider explores the intense and gritty origin story of Lara Croft and her ascent from a young woman to a hardened survivor. Armed only with raw instincts and the ability to push beyond the limits of human endurance, Lara must fight to unravel the dark history of a forgotten island to escape its relentless hold.”

Tomb Raider was developed by Crystal Dynamics and published by SQUARE ENIX, Eidos Interactive. It features a modified version of the Crystal game engine and was the first game to integrate AMD’s TressFX 2.0, which adds hair, fur and grass physics.

Total Average FPS

All the averages from all the game benchmarks are added up a totaled. This allows for a complete look at the overall performance compared to each of the other graphics card.


I started overclocking the Dual-X R9 285 OC using AMD’s own Catalyst utility. As, there are no third party overclocking utilities that support the card at this time, the video card voltage can not be adjusted, I was unable to adjust the voltage beyond the power limit of +20%. I tweaked the core speed first and then moved onto the memory speed. At this point the was running 1100Mhz on the core and 1570MHz (6000MHz) on the memory. This was an increase of 14% for the core and 12% on the memory. On an average, seeing in increase of around 7% percent increase in frame rates in our suite of benchmarks.


The Dual-X R9 285 OC does run a bit warm under load. Despite this, I found no reason to adjust the fan profile from it’s default setting.


Noise is a very subjective thing. While measuring dB level of noise can tell you how loud something is, it does not tell you the quality of the noise. Human hearing is the most sensitive in the 4000Hz range. This is roughly the same pitch as a crying newborn baby or the old adage, nails on a chalkboard. The human brain is wired to react to this frequency range and when we are unable to stop the noise, we become agitated.

For this test, the best case scenario is absolute silence. For the worst case scenario, I use the most annoying sounding and loudest video card I have at my disposal, the Nvidia 7600GT. The Dual-X R9 285 OC was always quiet. It was rare that I ever noticed fan noise except under extended extreme loads.

The Conclusion and Final Thoughts are next.
