I came across this benchmark comparison ( http://compubench.com/compare.jsp?config_0=14470292&config_1=18133965 ) between GTX-Titan and Tesla K40c, and the results seems very odd.Can someone please explain any possible reason behind this. How much would Tesla differ in performance if only single precision operations are being performed?

Answer 1

I'd opt for the Titan because it has more up-to-date instruction set capabilities. The GK110 ASIC that it is based on has SM 3.5 capability (e.g. read-through-texture, funnel shift) and also supports dynamic parallelism.

Maxwell is coming soon, but it will support more capabilities, not fewer, so you should use the GK110 as a baseline.
