How much faster are 12 bitboards for the pieces compared to int arrays in chess computers?

I programmed a chess computer and used int arrays for the position. Is it worth setting it up again because bitboards increase the speed enormously, or is the difference not that big after all?

You have to have optimised very hard so that this is something.

This may be faster, but may also be more susceptible to errors. And if the laps get better when you pull up soft tires depends heavily on the performance of your engine.

Can you change a subset of your program and thus measure the effect of optimizations?
