One aspect of differentiation between Android smartphones has always been how smoothly they scroll both in the OS and in the browser. Later versions of Android have addressed the issue by adding varying degrees of GPU acceleration to the OS, but there's still the need of raw memory bandwidth and the GPU horsepower to back it up. It turns out that Samsung's Galaxy S 2 delivers both.

The Vellamo data above measures scrolling performance, higher numbers being better of course. Compared to all high end GPUs available in Android smartphones today, the Galaxy S 2 is significantly faster. The Exynos 4210 features a dual-channel LPDDR2 memory interface along with a very powerful Mali-400 MP4 GPU. Combined with Samsung's GPU accelerated browser the SGS2 is able to deliver a huge leap in scrolling performance.

    I don't agree. Google aimed Android to run on as much hardware as posible, Adding GPU acceleration would have made the task much harder just look at how many SOC's WP7 runs on.

    I would rather have the huge choice hardware & features then the superficial Smooth UI of the other OS'es

    Superficial smooth UI?

    60 fps is VERY underrated by the tech savy. I have a windows phone 7 and a HP touchpad(had pre plus before the wp7). And navigating through the wp7 is so much faster. I am not talking about loading, but navigating through lists.

    And who cares what SoC is behind the screen if a higly optimized OS performes better with a 6-12 months old SoC than a unoptimized energy eating expensive SoC?

    Totally agree. There's nothing "superficial" about an interface that is smooth and fluid.

    When I play with an iphone it actually feels like I'm manipulating an object that's directly beneath the screen. This was on my old 3GS from 2009. Compare that to my current Samsung Fascinate (galaxy s) and the iphone (and WinMo7 for that matter) is so much smoother.

    A laggy interface just feels flaky, old, and instable. Reminiscent of the BSOD days from the 90s. I love Android but they better stop the choppiness by the time my contract runs out. :p
