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 the majority of 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.

On NVIDIA cards with Boost, the values discussed is the highest observed boost clock after overclocking.



Maximum overclock of our sample is 1090 MHz GPU clock (8% overclock) and 1730 MHz on the memory (15% overclock).

GPU overclocking reaches levels similar to previous Hawaii cards, so no improvement there. Memory overclocking seems to be held back by BIOS timing settings, as there is a hard wall at 1780 MHz. 1780 MHz runs perfectly fine, but 1781 MHz immediately crashes the card.

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 7.2%.
