Today I got to try out a Motorola Droid. Here is how its browser compares to Android 1.6 on my HTC Dream (Android Dev Phone / T-Mobile G1) in the V8 Benchmark Suite (version 5):
|RegExp||did not complete||16.5||–|
|Splay||did not complete||did not complete||–|
The precise ratios are different, but the same tests that showed the most improvement from Android 1.6 to 2.0 also show the most improvement from Safari to Chrome. Based on this plus the source code snapshot, I'm pretty sure that Android 2.0 is indeed using V8.
This is exciting news. It makes Droid the first shipping product I know that uses V8 on an ARM processor, although V8 has included an ARM JIT compiler for some time now. For mobile web developers (like me), it means we're one step closer to having desktop-quality rich web applications on low-power handheld devices.
Final thought: Although the Motorola Droid is still 100 times slower than Chromium on a Mac Pro, it's actually faster at some benchmarks than IE8 on a low-end Windows machine, or Firefox 2 on hardware from just a few years ago.
