Is there a FLOP/s specification for processors? Just wondering. If so, where can I find reliable data?

To specify the measuring of the number of floating-point operations per second one has to agree _what_ to measure.
You can measure the theoretical peak rate of common floating point ops like FADD, FSUB, FMUL and FDIV without memory interaction (i think that was the 'original' MFLOP rating).
Or you could agree on a specific workload like solving some equations with
LINPACK or the
SPEC CFP
