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 1190 MHz GPU clock (13% overclocking) and 1700 MHz memory (21% overclock).

GPU overclock on our sample didn't reach the levels we've seen on HD 7870 cards before it. In our previous testing, most of those cards reached 1200 MHz, some even went as high as 1260 MHz. Memory on the other hand overclocks a bit better: where we saw around 1600 MHz before, we now see 1700 MHz on the R9 270X.

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 15.2%.
