Overclocking

The overclocking results listed in this section were achieved with the default fan and voltage settings as defined in the VGA BIOS. Please note that every single sample overclocks differently which is why our results here can only serve as a guideline for what you can expect from your card.



Maximum overclock on our card is 1085 MHz GPU clock (26% overclocking) and 1375 MHz memory (15% overclock).

GPU overclocking is impressive. Even with the passively cooled design, the card overclocks well, reaching levels that are close to actively cooled HD 7850 cards. Memory overclocking is poor, which is probably due to the different memory chips used. I think PowerColor uses Elpida chips instead of Samsung or Hynix ones.

Important: Each GPU (including each GPU of the same make and model) will overclock slightly
differently based on random production variances. This table just serves to provide a list of typical
overclocks for similar cards, determined during TPU review.

Overclocked Performance

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 21.4%.
