[custom:mwc15]There's a pretty big story behind the Galaxy S6, concluding with a fresh new design that bares little resemblance to the Galaxy S5 before it. Of course we're also a year removed from the announce of the GS5, and that means specs have been improved pretty dramatically when looking at what Samsung put inside the Galaxy S6. Numbers don't tell the whole story of course, but putting the two phones in perspective in terms of specs is useful — here they are.
