I've been searching around to find some sort of chart or list that tells me how many levels of gradient there is for different single channel bit depths but I'm not having a lot of luck. Can anyone fill me in or link me to the info I'm looking for. I'd like to see from 2 all the way up to 20 or so.

The answer is not simple and is not the answer you will typically receive.
For example, with most systems there is no visible difference between 14-bits and 12-bits; and certain ly a factor of 4 difference.

You may want to look at what DxOMark call "Tonal Range".

What exactly are you trying to accomplish.
