The only difference between the two is the interface. Under the hood they are doing the exact same computations.

The minimize() function is a more recently-added wrapper (available since scipy version 0.14) that provides a more convenient uniform interface for the various solvers available in scipy.optimize. minimize(method='powell') and fmin_powell() both internally call the same _minimize_powell() private function that does the bulk of the work.
