At MIX10, Microsoft announced Internet Explorer 9 Platform Preview – (a light-weight frame around the core IE platform which includes rendering and layout, object model, parsing, and script engines. It’s a way to try out the platform, and experience improvements to performance, standards support and interoperability, enabling “the same markup” to work). If you're a consumer, or individual PC user, with no developer needs, this release isn’t for you. But if you're curious where Microsoft is taking its web browser, here's some info you can use. First, there’ll be a public download of the IE 9 Platform Preview. Microsoft has also created a Test Drive site a set of Web pages and applications designed to showcase features and enhancements included in latest platform preview, and Platform Preview User Guide. IE 9 script engine is codenamed "Chakra" which compiles JavaScript in the background on a separate core of the CPU, parallel to IE. It takes about 70 seconds to identify a 300ms difference between browsers.

IE 9 focuses very much on three key themes: Best interoperable HTML5, Hardware Accelerated Graphics, and High Performance Browser. IE9 will include extensive support for DOM, CSS3, SVG standards and XHTML. IE9 uses Windows’ modern graphics APIs and the PC’s hardware to accelerate all graphics and text that the browser draws on screen. A basic example involves a small, simple web page that animates images, having them follow the mouse pointer:

IE9 is the first browser to take advantage of modern hardware by shifting from CPU to GPU for hardware-accelerated SVG, enhanced JavaScript performance, and GPU-powered HTML5. By moving IE9 to GPU and taking advantage of latest Direct2D tech in Windows, webpages will load faster, graphics will be improved and users can take advantage of modern hardware in their Windows PCs while taking fewer resources from their PC.

“Doing HTML5 right – our intent from the start – is more about designing our browser’s subsystems around what these new apps will need than it's about a particular set of features. From beginning, we approached IE9 with the goal of enabling professional-grade, modern HTML5 support on top of modern hardware through Windows,” said IE blog on HTML5, Hardware Accelerated: First IE9 Platform Preview Available for Developers.
