How different "come from up" and "come up from"?

To "come from up" means that something came from somewhere that is above or in an upwards direction. To "come up from" includes the phrasal verb "come up", which means that something arose or appeared from somewhere, but it does not always have to be in an upwards direction. Ex: This box came from up in the attic. Ex: He came up from Florida to visit.
