A video is making the rounds online showing a speed test between the iPhone 6S and the Galaxy Note 7. Samsung's latest flagship is powered by the Qualcomm Snapdragon 820 processor with 4GB RAM whereas the iPhone 6S has a year-old processor and only 2GB of RAM. On paper, it should not be able to match the Galaxy Note 7 but the video shows that the Note 7 gets obliterated by the iPhone in this speed test. However, the video is not exactly an accurate representation of the Galaxy Note 7's performance.
Granted that the Galaxy Note 7 isn't as snappy as some of the other Android flagships but do bear in mind that Apple does a lot of work to optimize its hardware and software so that they work together almost perfectly. That's not the case with Android devices so they are already at an inherent disadvantage when it comes to overall system optimization.
This speed test doesn't cover some of Samsung's genuinely useful features like split-screen multitasking or the S Pen's Glance feature which are great for productivity as they enable users to use two apps side-by-side. The speed test doesn't indicate the handset's real-world performance as nobody is going to open 14 apps and render a video in the same exact sequence. What it does show is that performance is not a numbers game, optimization of software and hardware is much more important than the additional gigs of RAM a smartphone might boast.
