Overclocking



Manual overclocking has once more become more complicated with this generation. Since the cards are always running in the power limiter, you can no longer just dial-in stable clocks for the highest boost state to find the maximum overclock. The biggest issue is that you can't just reach that state reliably, so your testing is limited to whatever frequency your test load is running at (which usually changes all the time). That's why we're changing how we report overclocked GPU frequencies. Instead of listing the highest clock (that's only active for a short moment), we measure average GPU clock over a longer time period and report that value—which represents real-life experience much better.

With manual overclocking, maximum overclock of our sample is 1900 MHz on the memory (27% overclock) and +140 MHz to the GPU's base clock, which increases average GPU clock from 1950 MHz to 2045 MHz (5% 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.


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 9.6%.
