Overclocking
XFX Radeon HD 7850 DD OC spec |

Giving the card room to breathe, we increased the voltage to 1.2V (up from 1.125V) and raised the core and memory clocks until basic stability failure. XFX's card is a decent overclocker, as shown by the GPU-Z capture above. Already overclocked out of the box, the extra 200MHz core and 920MHz memory (effective) represents a worthwhile boost.
Perhaps the most graphically-intensive test in this suite, the overclocked XFX card's performance still comes up slightly short when compared to a GeForce GTX 660 OC in Far Cry 3.
