HTML5 Performance Benchmarks

Web Browser Grand Prix VIII: Chrome 16, Firefox 9, And Mac OS X

Facebook JSGameBench 4.1

Firefox 9 running under Windows 7 is able to pull off another significant win in Facebook's JSGameBench test, followed by Internet Explorer. Chrome places a distant third with a sub-500 score. Safari fills fourth place at close to 250 points, while Opera trails far behind with about 150 points.

The tables turn in OS X, as Safari achieves the high score of nearly 1400 points. Chrome moves up to second place, earning about 50 more points than its Windows version. Firefox drops dramatically to third place with 266 points, a mere sixth of its showing in Windows 7. Opera again brings up the rear, not even earning 100 points.


As a reminder, we use the single-pixel variant of the HTML vector charting test instead of the original two-pixel version due to unusually low scores achieved by WebKit-based browsers.
