Overclocking
Overclocking results listed in this section are achieved with the default fan and voltage settings as defined in the VGA BIOS. We choose this approach as it is the most realistic scenario for most users.
Every sample overclocks differently, which is why our results here can only serve as a guideline for what you can expect from your card.
For overclocking on Polaris, we applied the same percentage increase to each of the eight adjustable clock levels; this approach seems to provide the highest performance at the highest stability.
Maximum overclock of our sample is 1885 MHz on the memory (8% overclock). GPU overclocking reaches 1360 MHz (3% overclock).
Using these clock frequencies, we ran a quick test of Battlefield 3 to evaluate the gains from overclocking.
Actual 3D performance gained from overclocking is 2.4%.
