Internet Explorer 9 unvieled

IE9 shows off HTML5 and the Hardware acceleration. Fundamentally in the right direction. Needs more spunk and refinement.

Internet Explorer 8 has been gradually loosing sheen to the nimbler, faster competitors across. It might still be the most secure browser, but it had some catching up to do on speed and the HTML5 support.

So, Internet Explorer 9 had its work cut out and it delivers. It supports HTML5, boasts a new Microsoft JavaScript engine which is codenamed “Chakra,” and it’ll support new-fangled web technologies like CSS3,DOM and SVG2. Microsoft says one of its main goals with IE9 is to provide a faster browsing experience — always good news — though they don’t have things cranked quite as high as the competition just yet. Preliminary ACID3 tests on the preview show the IE9 scores a 55/100, up from IE8’s dismal 20/100 — a huge leap forward no doubt, but still a far cry from the Chrome, Opera, and Safari scores of 100. However these are still early days for IE9 and improvements are yet to step in.

Quoting IE Blog, IE9 was designed to “enable a new class of applications. These applications will stress the browser runtime and underlying hardware in ways today’s websites don’t. We quickly realized that doing HTML5 right – our intent from the start – is more about designing our browser’s subsystems around what these new applications will need than it is about a particular set of features. From the beginning, we approached IE9 with the goal of enabling professional-grade, modern HTML5 support on top of modern hardware through Windows.”

The IE9 uses a new script engine “Chakra” which powers its fast performance. The secret lies in the fact that Chakra compiles JavaScript in the background on a separate core of the CPU, parallel to IE.

IE9 is also the first browser to provide hardware-accelerated SVG support. IE9’s hardware-accelerated graphics takes full advantage of the PC’s hardware capabilities through the operating system to deliver significant performance gains on graphically rich, interactive web pages.

The IE platform preview also shares the progress on IE platform with the developer community so that the developers can create, contribute and evolve the eco-system and the products around IE9.

As with every incumbent IE is slow on many of the parameters compared to the Firefox, Safari and others, but IE being a majority share player in the browser markets, a robust and capable IE9 would be the key to the majority users accessing graphics rich pages in a better manner.
