Scumbria, You are obviously confident that branch misprediction occurs less frequently than some people fear. It would seem logical, given that the way programmers tend to use the additional CPU cycles available is with more sophisticated application presentation (e.g. audio/video/3D/pixel manipulations) which boils down to simple number crunching loops. Therefore, to some extent, the degree of misprediction might be inversely proportional to CPU clock rate. Do you know if there are any more concrete statistics gathered by actually analysing mainstream apps to see how much branching they do in normal operation?
