I am sure Cycles use only single precision float point operations, and
even more, force float in every possible places even if double precision
haddware suppport existand it faster than anything. There are many other
factors other than double/single float point Kepler issues, maybe
different caches, CU instruction sets, branch prediction assumption,
missed compiler optimisations that affect final Cycles performance.
