"A high score in the new benchmarks directly translates to better and smoother performance in similar web applications," Google said in a blog post.
Google also said Octane includes a more easily understood interface that adapts to the size of the device you're using.
The news tests include Box2DWeb, Mandreel, Pdf.js, GB Emulator, and CodeLoad.
- Pdf.js is based on Mozilla's PDF reader and measures how fast the browser decodes a sample PDF document.
- GB Emulator is derived from an open source emulator of a famous game console running a 3D demo, Google said.
- CodeLoad is derived from open source libraries like Closure, and jQuery.
Octane is now available on googlecode.com.
