OK, there is some performances that happen to match my machine.
If I look at the High-Accuracy mode (which is what we do), I have this
following samples :
our sin : 17 cpe, MKL sin : 10.5
our asinh : 11 cpe, MKL : 14.39
So seems some are better and some worse. Considering the difference, I guess
some of my algorithm is either non-optimal or have some pipeline hole.
I'll investigate
this and see how it fares.
