The OP tests the browser in three benchmarks, two of them are performance related , one being written by Google, and Chrome beats IE10 in that one (IE10 being the fastest in the other).
Additionally the conclusion makes me think that the OP has a bias toward Chrome.
I nevertheless think that Chrome is faster, however I am annoyed by all this IE bashing.
Even if IE was proven twice as fast in all test there is still plenty of reasons to bash it. Every version released is another variation developers will have to test on, branch code for and add some meta tags to work around it's quirks for years to come. At least that's how it's played out for the last 15 years or so. Time will tell if their recent changes will make things better, but better than horrible isn't really an admirable goal.
That said, yesterday I opened a site I've been working on and have rarely tested in any version of IE, it makes heavy use of the Google Visualization API with several interactive charts and tables on a single page, it destroys IE 6, 7 and 8, was OK in 9, but 10 rendered and executed it perfectly. So there is hope that the next 15 years won't be as plagued with IE quirks as the last but that is if, and only if, IE 7 to 9 can be eradicated faster than 6 was AND MS keeps up with the faster and transparent release cycles AND they support older OS versions AND they stop trying to add 'features' that cause developer lock-in AND developers stop buying in when they inevitably do. But that is a lot of ifs.
It does not matter which is fastest as long as both continue to make performance improvements where possible. We now have great performance from JavaScript (a key technology) in all modern browsers - which is the good news.
Yeah, misleading title. But it really surprised me that IE10 wins the Sunspider test. I guess all the IE-bashing has lowered my expectations of IE way too far. It is a wonderful thing for the internet that IE10 isn't completely worthless.
Seriously people should stop using SunSpider; it's way too old and simple (2007 design which means Jurassic, although it had a minor update in 2010). It's considered a microbenchmark suite by today's standards, doesn't mirror modern Javascript usage in any way: code style, size, features (eg typed arrays), libraries. Both Mozilla's Kraken and Google's Octane are much better.
Well, SunSpider is nowadays kinda a test how fast a browser can run through a loop. I'd still wager Robohornet is a little better (and it also considers things like scrolling and rendering speed and DOM manipulation for certain scenarios – plenty of things that probably contribute more to how fast a browser feels than raw JS performance).
