Although the placing of the other four browsers looks consistent, it appears that the WebKit developers didn't modify SunSpider v1.0 to account for Internet Explorer's incredulously low scores. Unfortunately, this means SunSpider returns to the bleachers, and these results won't be included in today's scoring.
Chrome takes the lead, followed by Opera Next in second place and the current version of Opera in third. At 66 seconds, Firefox places fourth, with long-term rival Internet Explorer bringing up the rear.
RIABench places Chrome in a commanding lead and IE10 in a distant last place, with Opera Next, Opera, and Firefox in-between the two. This test basically has Opera doing a trade-off, with Opera Next showing lower timed results, but the current version having higher FPS scores.
Futuremark also has Chrome in first place, with Opera Next taking the second-place position and the current version in third. Firefox and IE10 bring up the rear. In this test, Opera Next appears to be a marked improvement over the current version of Opera.
While Chrome comes away with another win in Browsermark, Opera Next is a much closer second-place finisher this time. Firefox places third, with Opera in fourth, about 2500 points behind Opera Next. IE10 places last yet again.
JS/DOM Composite Score
Chrome is the obvious winner, with Opera Next coming in second, Firefox placing third, Opera 12 in fourth, and IE10 clearly last. Opera Next appears to offer a healthy boost in JS/DOM performance over the current version.
