If a handsaw does the same amount of work on a log is a chainsaw does, which has more power? Why?

Power = W/t
Since both does the same amount of work, don’t worry about the variable W
Let’s talk about t, time
A chainsaw can cut into a log at a faster time than a handsaw can
Let’s assume chainsaw = 2 minutes
A handsaw = 6 minutes
Let’s pretend work = 12
12/2 = 6 power (chainsaw)
12/6 = 2 power (handsaw)
Based on this example, you can see that chainsaw has more power.
