Speed test: Samsung Galaxy Note5 vs. OnePlus 2 vs. LG G4

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. But how fast is it? Faster than the LG G4? Faster than the much more affordable OnePlus 2? This video intends to find out.

Here's an unscientific (but telling) test. Keep in mind that the Samsung Galaxy Note5 and OnePlus 2 have octa-core processors and 4GB of RAM, while the LG G4 has only six cores and 3GB of RAM.

In terms of screen resolution, both the Note5 and G4 are at QHD (1,440x2,560px), while the OnePlus is at 1080p (1,080x1,920px). The LG G4 should finish last, right? Well, here’s why you shouldn't trust "on paper" specifications.

The power of the Exynos chipset is plainly visible in the video encoding part of the test. The downclocked Snapdragon 810 in the OnePlus 2 didn’t really seem faster than the Snapdragon 808 in the LG G4.

The video doesn’t show how high-end games perform though – S810's better GPU smokes the G4 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 G4 (with 1 gig less) kept them in RAM.
