cmov turns a control dependency into a data dependency. It is still there just in a different way. (its like the Fourier Transform of instructions - lolol).

I haven't seen cmov lose to a conditional in a few years (on very recent Intel hardware). Maybe there might be some circumstances where in creates a loop carried dependency that wrecks the optimizer, but I haven't seen one in a minute.

To be fair - cmov versions often involve some extra compution to get things in a form where cmov can be used, and I often just opt for the well predicted conditional since those couple extra instructions to set up the value to move can be avoided.
