Overclocking

The overclocks 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, that's why our results here can only serve as a guideline for what you can expect from your card.



Maximum stable clocks of our card are 1120 MHz core (18% overclock) and 1515 MHz Memory (26% overclock).

Compared to other HD 7850 cards we see significantly lower overclocking, which is quite surprising given the low temperatures of the card. Nevertheless, overclocking still provides large gains in performance, putting the card on par with the HD 7870.

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,
reached 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 18.6%.
