Answer 1

To add to the great answers here. It’s a common misconception that 32 bit is faster than 16, 64 faster than 32 and so on.

Yes if software is specifically designed to take advantage of the larger integers then yes its faster, if not it’s the same or slower.

I’m no engineer but I think you could build a 16 bit processors that could handle higher clock speeds than a 64 bit cpu, while running 16 bit code that is.
