To start with the basics, IE 10, which has been available on Windows 8 and Windows RT since they were introduced, is only being made available for Windows 7. If you use Vista or XP, you're still locked into IE 9 and IE 8, respectively.
Chrome is available on XP on up, on Snow Leopard and higher on Macs, and on most contemporary versions of Linux.
Both Web browsers claim that they're doing a great job of supporting Web standards. These include HTML5, CSS3, and Document Object Model (DOM) specifications. In so much as this can be tested, however, Chrome seems to have a comfortable lead. On the HTML5 Test site, Chrome scored an impressive 463 out of a possible top score of 500, while IE came in with only 320.
Each browser has its own features. Chrome 25, for example, has started to incorporate voice-recognition. IE 10, with its roots in touch-friendly Windows 8, is touch-screen ready. Oddly, IE 10's menu bar, which is at the bottom of the screen in Windows 8 by default, is at its more natural -- as far as I'm concerned -- top position in Windows 7.
Features are rather beside the point.
The bottom line for Web browsers is speed, so here's how the two did on the benchmarks. To put the two to the test, I ran both on a Gateway DX4710 running Windows 7 SP1. This PC is powered by a 2.5-GHz Intel Core 2 Quad processor and has 6GBs of RAM and an Intel GMA (Graphics Media Accelerator) 3100 for graphics. It's hooked to the Internet via a Netgear Gigabit Ethernet switch, which, in turn, is hooked up to a 100Mbps (Megabit per second) cable Internet connection.
On SunSpider, where lower results are better, IE 10 blew Chrome 25 out of the water. IE 10 scored 182.63-milliseconds to 521.1-milliseconds.
With this test, higher is better. As you probably would have guessed, since Octane is used by Google to help build Chrome, here Chrome beat IE to a pulp. Chrome came in with a score of 9,138 to 3,742.
Peacekeeper is another benchmark where the higher score the better the browser. Once again, Chrome wins handily on this test. Chrome came in with 2,529 to IE's 1,591.
Like its forefather, lower scores are better on it. Somewhat to my surprise, Chrome once more beat IE handily. This time, Chrome scored 3,717.4-milliseconds to IE's 9,017.1-milliseconds.
In this test, higher scores are better. For once we have a close result and it may surprise you. IE edged out Chrome with a score of 115.38 to 102.73.
So, which is the best? Well, for my money, Chrome seems the easy best pick. Not only does it tend to be faster, usually far faster, than IE, it runs on almost every desktop platform you're ever likely to use and it's more HTML5 compatible. That said, if you're running Windows 7and you must use IE, this latest Microsoft browser is a good choice.
