AllThingsD reports that Spaceport.io, which makes a cross-platform gaming SDK, has tested the speed of HTML5 rendering on iOS and Android. The results show that iOS is faster by far.
Spaceport used its own benchmark, called the "PerfMark," which counts the number of moving images on a screen at 30 frames per second, a rate that provides a near-native user experience.
The group demonstrated that HTML5 games ran significantly faster on iOS 5 vs. the Android devices tested. Specifically, iPhone 4S scored 252 PerfMarks and the iPad 2 scored 327. In comparison, the newer Samsung Galaxy Nexus smartphone scored 147 and the Kindle Fire scored only 25. You'll find more details at VentureBeat.
As for tablets, the iPad 2 beat every Android device it was pitted against. "HTML5 is getting faster over time, as seen in the latest OS updates across Android and iOS," said Spaceport.io founder Ben Savage. "Although this is a welcome trend, there is still a long way to go."
Several companies are jumping on the HTML5 bandwagon, hoping to create a game that will run on many platforms. It will be interesting to see how the next-generation iPad, "iPad 3" if you will, would score on Spaceport's test.
