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 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 here are base clock. Boost will further increase clocks.



Maximum overclock of our sample is 1140 MHz GPU base clock (23% overclocking) and 1670 MHz memory (19% overclock).

Overclocking works very well, providing lots of headroom for your overclocking adventures. Memory overclocks nicely, too, because of the Hynix chips Sapphire used, although both the HD 7850 and HD 7870 from 2012 overclock identically.

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 21.3%.
