Next up is a look at the performance-per-Watt.

The performance-per-Watt of the GTX 970 through GTX 980 Ti and TITAN X were all close to the same with being well in front of Kepler and the lower-end Maxwell cards.

The performance-per-Watt with LuxMark was similar to the JuliaGPU result. The performance-per-Watt of the GTX 950 is about three times better than that of the GTX 950. The GTX 980 is about 2.5x that of the GTX 680.

NVIDIA's next-gen Pascal architecture is only a few months away that should be very interesting for carrying out a similar comparison at that time.

Here's a look at the overall AC system power consumption when running all of the OpenCL/CUDA benchmarks for this article.
