Benchmarks - power, temps and noise
Sapphire's faster-than-default clocks are achieved without touching the voltage, which is 1.112V by default. Still, NVIDIA's card beats it out.
The graph makes little sense on first glance. We're showing the higher-clocked Sapphire - in the second BIOS position - to have better temps. Things begin to make sense when you consider the fan-speed profile is more aggressive when using this setting. Logs show the two fans to spin at 1,900rpm with the 'BP1' setting and 2,400rpm for 'BP2'.
And it's the speed of the fans that largely dictate system noise. Very quiet in standard form and not too noisome with on the second setting, the Sapphire cooler is better than the reference in every way.
