Google Chrome 23 manages to keep Chrome 24 out of the top spot, with Opera 12 coming in a distance second place -- Opera's best score to date in this series of tests.
Firefox 18 achieves a better score than Firefox 16, but this is a test where Mozilla trails far behind the pack.
A close fight between Firefox 18 and Chrome 24, with Firefox 18 coming out in the lead. It seems that both Mozilla and Google have worked hard on their respective browsers to improve their score given the significant improvement.
Internet Explorer 10 holds fifth place, and Microsoft has a lot of work to do if it is to have a chance of beating Mozilla or Google in this test.
This is the new kid on the browser benchmark block. It is Google's vision of a modular, independent, and open-source benchmark comprising of tests created and voted on by developers and designers, with consultation from standards bodies and vendors.
RoboHornet is currently in alpha testing, so it is very much a work in progress and as such the results should be taken with at least a small pinch of salt. That said, it is a test worth keeping an eye on, and is another metric by which to test modern browsers.
Firefox 16 narrowly beats Firefox 18 to the top spot, with Opera 12 in third place. Chrome 23 is in fourth spot, with the newer Chrome 24 also being beaten by its older brother.
This is Google's new benchmark, based on the V8 suite. This is the test suite that Google puts the Chrome browser through.
Google's Chrome browser comfortably beats the competition, with Firefox 18 a distance second. Internet Explorer 10 and Opera 12 are in a distance third and fourth place.
So, with all that, which browser is best?
As with every browser benchmark, it's hard to draw any definitive conclusions from the data given that there's no overall winner. Chrome 24 grabs the top spot in two of the tests, with the other top spots going to Internet Explorer 10, Chrome 23, Firefox 18, and Firefox 16, making statistically the latest version of Google Chrome the overall winner.
That said, the score that Microsoft's Internet Explorer 10 achieves in the SunSpider benchmark is impressive, and it pulls in a respectable score in the other four tests, so it's clear that Microsoft has done a lot of work to make its browser better.
It's also interesting to note that in several of the tests, the older version of the browser beats the new release, which suggests that either Mozilla and Google aren't focusing as heavily on speed as they once were, or that the tests don't accurately reflect they improvements made in the browser.
