Sound, Overclocking, and Power Consumption

When testing a third party graphics card versus a reference design there are 3 key aspects to look at—sound performance, overclocking ability, and power consumption.

As we mentioned earlier, the Strix 1080 Ti has a feature allowing it to run without the fans for temperatures up to 55 degrees Celsius, contributing to its low idle sound level.

However, even at full load, the Strix GTX 1080 Ti is the quietest card of the bunch, with an impressive 4.1dB difference from the EVGA SC2 option and 4.6dB quieter than the NVIDIA blower-style reference design.

The Strix model we are looking at today is the factory Overclocked model, so we expect some significant gains from the reference 1080 Ti. The Strix card doesn't disappoint, with our sample reaching a consistent clock speed of 1923 MHz, an 11% increase in clock speed over the reference design.

To evaluate how much additional headroom there was for overclocking past the stock settings, we ran a couple of quick overclocking tests using the ASUS GPU Tweak II software.

With some simple tweaking, we were able to apply a 70 MHz offset to this card, while maintaining stability in Unigine Heaven and staying under 70 degrees Celsius on the GPU!

With our simple overclock of +20% to the power target and a +70 MHz offset for the GPU core, we were able to achieve an average clock speed of 2024 MHz on our Unigine Heaven test, an extra 7% over the default settings for this card, and over 17% better than the reference 1080 Ti design with stock settings.

As always, more clock speed comes with higher power consumption for the Strix GTX 1080 Ti. Still coming in under the air-cooled AMD Vega 64 reference design, the Strix hovers just below the 300W mark, taking full advantage of the two 8-pin connectors available for power draw
