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.
On NVIDIA cards with boost, the values discussed here are base clock. Boost will further increase clocks.
Maximum overclock on our card is 1250 MHz GPU clock (14% overclocking) and 1800 MHz memory (11% overclock).
GPU clock reaches exactly the average clock for Bonaire. Memory overclocks much better than on HD 7790, thanks to the new high-frequency GDDR5 memory chips used, but I could not overclock the memory beyond 1800 MHz, which looked more like a software issue than a limitation of the memory itself.
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 12.0%.
