Note that that's the GB single precision benchmark's plot which shows
surprising large performance gap between 780 Ti and 980 - perhaps
there's something in the OpenMM GB kernels that favors Maxwell.
This is the explicit solvent performance plot:
showing ~25% improvement over a 780 Ti (still pretty impressive). This
is close to what I'd have guessed based on extrapolating the 750 Ti
Also note that this is OpenCL performance which is inherently worse
than CUDA and the OpeCL-CUDA difference may not be the same across all
