FLOPS estimation

The following formula can be used for estimating FLOPS for a CPU:
FLOPS = FLOPS_per_cycle * cores * frequency
Flops per cycle might be hard to find, they should be in the technical documentation of the particular CPU series, e.g. Haswell. Some of it can be found here: http://stackoverflow.com/questions/15655835/flops-per-cycle-for-sandy-bridge-and-haswell-sse2-avx-avx2. Sometimes there is a doc from producer with FLOPS: http://download.intel.com/support/processors/xeon/sb/xeon_5600.pdf
