Apple made some bold claims about its new A5X chip, claiming it would give a 4x graphical boost over Nvidia's Tegra 3. At the same time, the Tegra 3 is a powerhouse of computational processing. So lets put 'em to the test.
First, the usual caveat: benchmarks only mean so much. There are a lot of anomalies that are hard to account for, and benchmarking across different operating systems is problematic at best. User experience is more important. K? K.
Results in the SunSpider test were extremely inconsistent, but the two tablets scored within the same range. In a race-type test in which lower times win, both had peaks in the 1680-millisecond range, and both had troughs down to the mid-1800s. We're calling this one a draw, but we go on record as being suspicious of the results because of the variance.
BrowserMark: Transformer Prime
The BrowserMark test gave much more consistent results, with less deviation, which made it seem more reliable. Higher scores win this test, which is designed to test Java and HTML rendering. After several runs, the Transformer Prime averaged 107,632, and the iPad averaged 99,908, making the Android device 7.2-percent faster. But again, different browsers will yield different results.
GLBenchmark 2.1: iPad
The iPad definitely won the graphical performance tests. In the Egypt standard test, the iPad processed 6740 frames at 60fps; in the Pro standard test it processed 2974 frames at 60fps. Compare that to the Prime, which clocked 5080 frames at 52fps and 2775 frames at 56fps, and the winner is clear. Watching the tests go, the iPad looked very smooth, whereas the Transformer Prime struggled with artifacting and other graphical anomalies.
Did the iPad win? Yes, solidly. But not even close to the 4x performance Apple promised, so it's unclear where the company got that number they were boasting about.
