We say a long overdue goodbye to SunSpider in this installment. Kraken also gets the boot, though it is being replaced by Rightware's Browsermark 2.0 (the first version was mobile-only). We're also vetoing the inclusion of Google's Octane for the very same reason that V8 is no longer in the Grand Prix: Chrome's margin of victory is contrary, and potentially crippling to the other JS results. RIABench and Futuremark's Peacekeeper remain, bringing our total number of JS tests to just three.
This benchmark has the browsers finishing in exactly the same order on both versions of Windows: Chrome, Opera, Firefox, IE10, IE9.
Peacekeeper places Chrome in the lead on both platforms, followed by Opera. Firefox takes third in the newer version of Windows, while the Internet Explorers beat Mozilla's browser in Windows 7. Once again, both Opera and Firefox exhibit better scores in Windows 8.
The placing order is the same for both OSes: Chrome, followed closely by Firefox, and Opera in a distant third place. The IE duo falls to an even more distant fourth/fifth. Firefox again favors the newer Windows.
This result is the geometric mean of the three JS tests and Dromaeo.
Alright, now it's time to check out performance results for next-gen technologies like HTML5 and CSS3, followed by hardware acceleration.
