Benchmark Results: Real-World
Early on, we discovered how difficult it is to benchmark tablets.
Benchmarking responsiveness with a camera is the easiest approach. Of course, normal cameras don't cut it, since they only shoot at 29 FPS. That's unacceptable if you're trying to measure precise time differences. Going the stopwatch route is no better, due to human-introduced errors. As a result, we're using a 1000 FPS high-speed camera to measure performance. Since one frame equals one millisecond, it’s possible to measure timing with a high degree of accuracy.
Compared to the competition, Sony's interface enhancements only seem to slow down the time it takes for Android to boot.
Android's Chrome browser definitely seems more bloated than iOS' Safari, which is what we've found time and time again.
Input lag is the time it takes from pressing a key to text appearing on the screen. This tells you how fast a tablet is registering an action. Ideally, you want low input lag so that you don't feel like the tablet is stuttering as you type or click buttons.
