Overclocking
With manual overclocking, maximum overclock of our sample is 1860 MHz on the memory (6% overclock), restricted by the adjustment range in Wattman. For some reason, AMD chooses to artificially limit overclocking potential of their cards. GPU overclocking did max out the slider range, too.
The maximum stable overclock was 1820 MHz Boost, which increases average GPU clock from 1730 MHz to 1772 MHz (2% overclock).
Testing notes & interpretation- Overclocking results listed in this section are achieved with the default fan, power, and voltage settings as defined in the VGA BIOS. We choose this approach as it is the most realistic scenario for most users.
- Each GPU (including each GPU of the same make and model) will overclock slightly differently based on random production variances.
- The data in this table shows comparable overclocks, using identical conditions, from previous TechPowerUp reviews.
Using these clock frequencies, we ran a quick test of Unigine Heaven to evaluate the gains from overclocking.
Actual 3D performance gained from overclocking is 3.2%.
