Bech marks are highly subjective, and frankly i don't even pay attention to them anymore. It depends on SO many factors. The iPhone 5s keeps close and a believe passes the M8 and s5 in some i believe and it's only a dual core phone with 1GB or ram. Its all how everything is optimized, how heavy the UI is. Blah, blah, blah, blah.
But i get it, its a game of who can get the higher number lol. I just judge my phone now of days on how well and fast it runs. I haven't even put a benchmark app this time around on my M8 or my S5
