It would appear as though Google have been tasting Android 2.3 aka Gingerbread and Android 3.0 aka Honeycomb recently. Indeed, if you head on over to AIRBenchmark you will be able to see an Android OS version of 2.3 and 3.0 listed, with their accompany AIRBenchmark scores. This website provides benchmarking facilities and score logged for Adobe’s AIR. “Adobe Integrated Runtime (AIR), also known as Adobe AIR, is a cross-platform runtime environment developed by Adobe Systems for building rich Internet applications using Adobe Flash, Adobe Flex, HTML, or Ajax, that can be deployed as desktop applications.”
At the time of writing, there are build versions showing up, GRH47B and GRH14B, the most recent of which is the Dalvik/1.4.0 (Linux; U; Android 2.3; Nexus One Build/GRH47B. It would appear as though the scores weigh in at 301 for Gingerbread and 584 for Honeycomb, compared to the 577 that Froyo 2.2.1 gives. The downside is that these versions can be faked, so who knows whether this is the real thing or not. Also, I would have thought that Google have their own internal methods for testing things types of things.
