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 1245 MHz core (25% overclock) and 1545 MHz Memory (26% overclock).

We see very good overclocking potential for GPU clock, which is the best of all HD 7850 cards that we've reviewed so far. Memory overclocking works great too, and ends up higher than all custom designs, yet can not beat the AMD reference board.

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 10.6%.
