Here are the details of all the new tests, courtesy of Google:
- GB Emulator is derived from an open source emulator of a famous game console running a 3D demo.
The source code of Octane itself is available for download, too.
With Kraken, Mozilla also offers a benchmark that aims to measure real-world browser performance. In my own informal tests with Octane, the current release version of Chrome generally beat the latest stable release of Firefox by a wide margin (the same, by the way, is also true for the Kraken test).
