Samsung is enjoying a comfortable performance lead with its Exynos 7420 that it didn't even overclock it for the Galaxy Note5, usually we see the Note get a souped up version of what the Galaxy S got.

The video doesn't show how high-end games perform though - S810's better GPU smokes the G3 even when you ignore the difference in resolution. But even pure performance isn't the end of it. Samsung's TouchWiz does a poor job of memory management and it has to reload the two games, while the OnePlus 2 and LG G3 (with 1 gig less) kept them in...
