Today at the Professional Developers Conference in Redmond, Microsoft announced the release of the Internet Explorer 9 Platform Preview 6. This new preview represents a series of improvements made to the rendering engine since preview 5, and of course the IE9 beta that was released back in September. Like the previous platform previews, this one does not have the full Internet Explorer UI, but rather a minimalistic container targeted at developers who wish to test the new functions of the IE9 rendering engine.
The next milestone for IE will be a release candidate build, which will of course contain the full UI.
Below is an image representing the sun spider benchmark results on this new Platform Preview as compared to other browsers (as well as previous builds of the IE9 engine)
