17-Way Linux Graphics Card Comparison With Civilization Beyond Earth

Consuming the most energy of the hardware tested was the GeForce GTX 780 Ti.

To no real surprise, the GeForce GTX 970 and GTX 980 were delivering the best performance-per-Watt. The Maxwell-based GTX 970/980 clearly deliver greater performance/power efficiency than the earlier Kepler GPUs and was also better than all of the AMD GPUs tested -- including the Tonga and Hawaii GPUs, given the crippled Catalyst performance under Linux.
