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.

Overclocked Performance

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 4.7%.

Power Limits

All NVIDIA graphics cards have a power limit defined in the BIOS, which limits power draw by adjusting Boost frequencies accordingly. A second limit exists that defines the maximum TDP adjustment limit for user overclocking; i.e., how far the power slider will go. In the second chart, the (+xx%) value lists the percentage increase from the tested card's default power limit to the highest available manual setting—the slider's adjustment range.
