Web Browser Grand Prix 2: The Top 5 Tested And Ranked

SunSpider v0.9.1

Opera is the clear winner in the latest version of WebKit's SunSpider JavaScript benchmark. Trailing by one hundred milliseconds is Chrome, with Safari close behind in third. Fourth place finisher Firefox is nearly three times slower than the top three, while IE8 is just completely off the charts, taking more than five times longer to finish than Mozilla.

Google V8 Benchmark v5

As we might have predicted, Google Chrome scores the most points in the company's V8 benchmark. Opera comes in 450 points behind Chrome's score, while third-place finisher Safari trails the leader by over one thousand points. Firefox earns just shy of 300 points. Again in last place, IE8 receives a score of slightly over sixty.


The placing in JSBenchmark closely resembles that of the Google V8 test. Chrome again places first by a significant margin, but this time Apple's Safari slightly edges out Opera for second place. Firefox fills fourth place with IE8 floundering behind in fifth.

Mozilla Dromaeo JavaScript

Once again, Opera displays troubling results. It is simply too far ahead of the other contenders for this score to be valid. Chrome therefore becomes the winner here, with second-place Safari pulling in less than half the number of runs per second. Firefox takes fourth with just shy of sixty runs per second, while Internet Explorer scores fifty.

On a side note, Chrome v5.0.375.86 also displayed seriously skewed results in this test--almost a thousand more runs than Opera! However, the slight version change to 5.0.375.99 brought the outcome back in line with reality.
