Well, this is a measure of the efficency of the pipline of the floating point
operations on the CPU and of the bandwidth/efficency of the bus connecting the
CPU.

It has very little to do with chess.

Of course a high bandwith is good for a parallel chess program, but the
performance on integers in non vectorial calculcations is the number that
matters for chess.
