Repeated tests show that iOS performed far better at running
animations than Android. The newest iPhone 4S scored 252 PerfMarks
and the iPad 2 score 327. That compares to just 53 for the iPhone
3GS from 2009. By comparison, the Samsung Galaxy Nexus smartphone
scored 147 and the Kindle Fire scored only 25.
The iPad 2 beat every single Android device tested. The newly
released Android Galaxy Nexus was the only Android smartphone that
could handle images at 30 frames per second.
Some Android tablets performed poorly despite their powerful
hardware. The Samsung Galaxy Tab 10.1 scored 65.
I wonder whether they used Chrome or the built-in (slower) “Browser” to test the Galaxy Nexus. Anyway, I suspect the iPad 2 only has about two days left at the top of the list.
