Acoustical Testing / Power Consumption
What you see below are the baseline idle dB(A) results attained for a relatively quiet open-case system (specs are in the Methodology section) sans GPU along with the attained results for each individual card in idle and load scenarios. The meter we use has been calibrated and is placed at seated ear-level exactly 12” away from the GPU’s fan. For the load scenarios, Hitman Absolution is used in order to generate a constant load on the GPU(s) over the course of 15 minutes.
As you may have already guessed, the ASUS GTX 1050 Ti Dual and EVGA GTX 1050 SC are both extremely quiet cards. Then again, there have been very few GPUs this generation that we can accuse of being overly loud. Hopefully this trend continues.
System Power Consumption
For this test we hooked up our power supply to a UPM power meter that will log the power consumption of the whole system twice every second. In order to stress the GPU as much as possible we used 15 minutes of Unigine Valley running on a loop while letting the card sit at a stable Windows desktop for 15 minutes to determine the peak idle power consumption.
Now these results may require a bit of an explanation since they point directly towards NVIDIA being a leader –by a long shot- in power consumption metrics.
The GTX 1050 Ti and GTX 1050 actually share a lot in common here since even though the smaller sibling has an SM locked away, it still consumes about the same amount of power due to its higher frequencies. Naturally, the overclocked EVGA card requires a bit more juice but the few watts really aren’t anything to worry about, even for those of you without a modern PSU.
Against AMD cards, Pascal really shows its true colors. Both of these new GPUs outperform AMD’s RX 460 2GB but require almost 20W less. That’s nothing short of incredible and it highlights just how far behind the Polaris architecture really is.
