IE9 vs Chrome 10 vs Firefox 4 vs Opera 11.01 vs Safari 5 - The BIG browser benchmark

Now that Mozilla has finally released Firefox 4 to the masses, it’s time for a BIG browser benchmark where we take the leading browsers and pit them against four of the toughest benchmark tests available to see which is the tortoise, and which is the hare.

Note: This post has been updated for the final release of Firefox 4.

Here are the browsers that will be run:

• Internet Explorer 9 (9.0.8112.16421) 32-bit


• Internet Explorer 9 (9.0.8112.16421) 64-bit


• Firefox 4


• Chrome 10.0.648.151


• Safari 5.0.4


• Opera 11.01

Here are the tests that the browsers will face:

• SunSpider javascript 0.9.1 - A javascript benchmark developed by Mozilla with a focus on real-world problem solving.


• V8 Benchmark Suite - A pure javascript benchmark used by Google to to tune the V8 javascript engine.


• Peacekeeper - FutureMark’s javascript test which stress-tests features such as animation, navigation, forms and other commonly utilized tasks.


• Kraken 1.0 - Another javascript benchmark developed by Mozilla. This is based on SunSpider but features some enhancements.

All testing carried out on a Windows 7 64-bit machine running a Q9300 2.5GHz quad-core processor with 4GB of RAM and an NVIDIA GTX 260 graphics card.

On with the testing!
