Precision: 8, 16 or 32 bit?

Converting the hex to decimal is always going to be regardless of precision.  
F5 = Red = 245
00 = Green = 00
0d = Blue = 13

Using a higher precision does give a larger file size.
You can see the benefit of a higher depth especially with gradients, less 'ramping'
As far as I know, many of the internal calculations are using 32 bit fp even if using 8 or 16 bit

I confirm, AFAIK all internal calculations are now done in 32-bit FP linear so 32-bit FP linear is the fastest option if you have the RAM (4x the RAM of the 8-bit precision).
