Android tablets running the NVidia Tegra 2 chipset have a substantial performance edge over Atom-based tablets, according to a series of benchmark tests performed for Tweakers. Researchers tested four tablets running Android 3.0.1 (Honeycomb). The lone Atom tablet tested, a prototype from Compal Electronics with a dual core 1.5GHz Oak Trail CPU, posted a Caffeinemarks score that was barely one-fourth that of the slowest Nvidia tablet. Caffeinemarks is a synthetic test that gauges the speed at which Android apps will run on a given system.
The three tablets with Nvidia Tegra 2 processors were the Acer Iconia Tab A500, Samsung Galaxy Tab 10.1., and ASUS Eee Pad Transformer. All three had Caffeinemarks scores of 6200 or higher, versus the Compal tablet's mark of 1562. The standard score of 100 is based on a 133MHz Pentium running Windows 95 and the Sun JDK 1.1 interpreter.
The researchers also reported that the Compal pad seemed sluggish in comparison to the others, so the lower score was not unexpected.
