Is a logical right shift by a power of 2 faster in AVR?

Question

I would like to know if performing a logical right shift is faster when shifting by a power of 2

For example, is

myUnsigned >> 4

Answer 1

If your targer processor has a bit-shift instruction (which is very likely), then it depends on the hardware-implementation of that instruction if there will be any difference between shifting a power-of-2 bits, or shifting some other number. However, it is unlikely to make a difference.
