Web Browser Grand Prix: Chrome 20, Opera 12, Firefox 13

The Top Five Browsers, Tested And Ranked

This article marks our return to Windows 7. Believe it or not, more than nine months have passed since we last ran a completely Windows 7-based Web Browser Grand Prix. In the interim, we've switched venues to OS X (twice), Ubuntu, and even Windows XP. While all that OS-hopping provided a nice detour, Microsoft's current desktop operating system is most definitely the big show. This is also, then, the first Windows 7-based browser comparison employing the new scoring system introduced in Web Browser Grand Prix: Chrome 18, Firefox 11, Windows XP. Our Core i5 test system was upgraded from Intel's old Lynnfield design to a more modern Sandy Bridge-based chip, and the Radeon HD 4870 was recently replaced by a Radeon HD 7770. The benchmark suite also receives significant upgrades. We're removing five of the older benchmarks, adding ten new ones, and implementing composite scores for nearly every category of testing.

But before we get to the numbers, let's catch up on what happened in the world of Web browsers since our last installment of the Grand Prix.
