The iPhone 6 tended to run games more smoothly, with a higher average frame rate that was very stable and rarely dropped below 30fps. The Galaxy S6 came a pretty close second, with a greater frequency of performance bottlenecks that pushed the framerate below the 30fps threshold. The HTC One M9 and Nexus 6 came third of and fourth respectively, showing serious performance slow-downs in some games.
There are some caveats to GameBench's testing, for example the Galaxy S6 played some games at a higher resolution than the iPhone 6 (1080p versus roughly 720p). Also, it's possible that some games were better optimized for one platform than another. However, the tests do quantify what users would likely see in real-world performance.
GameBench's principle measurements are based on “frames per second” (fps). This includes the median fps, which represents the commonest frame rate experienced in the game and broadly correlates to what the player observes as graphical smoothness. A strength of using the median is that it naturally overlooks fringe results, such as the 0fps or 60fps that commonly occur during a game’s menu or loading screens.
