Note that in terms of pure compute performance the new 16nm Nvidia GTX 1080 (2560 shaders at up to 1733 MHz = 8873 SP GFLOPS) barely equals the performance of the previous-generation 28nm AMD Fury X (4096 shaders at up to 1050 MHz = 8602 SP GFLOPS). Of course the 16nm chip does so at a significantly lower TDP (180 Watt) than the 28nm chip (275 Watt), so it will be interesting to see what Nvidia can achieve at a higher thermal/power envelope with a more high-end card... I am waiting impatiently to see how AMD's upcoming 14nm/16nm Polaris chips will fare, but from the looks of it it seems like Polaris will beat Nvidia in terms of GFLOPS per Watt.
