Considering one point of AP has the value of 21.75 Gold and one point of AD 35 Gold, you would gain around 1.6 times the amount of AP for the same price as AD. From a cost-efficiency perspective of course. This means that AP breaks even damage wise on her passive around level 6, with AP even being a little bit stronger and outscales AD cmopletly with level 11.

If you have 100 AD you would have 160 AP for the same gold. From level 1 to 5 your passive deals 100 bonus damage with AD, but only 88 bonus damage with the AP value. At level 6 however the bonus from AD is still the same, while the bonus damage from AP increases to 112. And at level 11 it increases again to 136 and of course at level 16 it maxes out at 160 bonus damage. That means that until level 5 AD is more cost efficient and simply stronger, from level 6 onwards it's almost even and at level 11 AP is more cost efficient and scales harder.

This however doesn't take into account AA's, E's, Q's or her ultimate. But since AA's and E's are stringer on AD, while Q and ult are stronger with AP it kinda evens out.
