The NVIDIA GTX 1080 Ti Performance Review

Acoustical Testing

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.

On the previous page, we saw an interesting trend of higher clock speeds and lower fan speeds versus the TITAN X. Obviously, that allows the GTX 1080 Ti to be quieter than NVIDIA’s previous generation flagship. Let’s be clear here though: this isn’t a quiet card by any stretch of the imagination, but if you want near-silence it may be worthwhile to wait for custom board partner designs….just be prepared for those cards to dump all the heat back into your case.

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.

The power consumption results are somewhat interesting. Even though the GTX 1080 Ti is the most power hungry NVIDIA card we’ve tested in quite some time, much like the TITAN X its performance per watt ratio is straight through the roof. This thing is pulling about 5% more wattage than a GTX 980 Ti, yet it offers nearly double the performance. That’s quite incredible and it shows the inherent efficiency of NVIDIA’s latest chip designs.
