Overclocking
Manual overclocking has gotten a little bit stabler than on AMD's first drivers. We still had to raise the power limit to its maximum to see any meaningful overclocking.
With manual overclocking, maximum overclock of our sample is 1900 MHz on the memory (9% overclock) and 2100 MHz on the GPU, which increases average GPU clock from 1994 MHz to 2043 MHz (2% overclock). Memory overclocking is now limited by the length of the slider in Wattman, which stops at 950 MHz.
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 1.8%.
