Apparently AMD are using a different version of ie 9 preview that is available from the public, (presumably the developer one). That pretty much renders all the browser tests invalid.

Couple of weird things i noticed about the Kitguru comparison video, they are running a different version of the Platform Preview than is available to the public. I just downloaded the latest one from M$ which is 1.9.7916.6000, the version they are using is 1.9.7930.16394.
