HTML5 Browser Comparison
HTML5 is coming. Not soon, but it is on the horizon. It boasts several new features. The most exciting of which (for me anyway) are new multimedia capabilities. It could bring about the end of plugins like Flash and Silverlight for video/audio playback on the web. While this next revision, is not set to become a W3C recommendation until around 2020, many of its features are already usable and starting to appear online. How do today's browsers fair with current HTML5 content? Well I decided to do some highly unscientific testing with html5test.com.
The results were not to surprising. Apple's Safari was the clear winner with a score of 208. The loser was Microsoft's Internet Explorer with a miserable 27. However, you should keep in mind that HTML5 is not exactly expected to roll out over night. For now this is more of a curiosity than a benchmark. Now, with that disclaimer out of the way, on to the results.
Results
- Apple Safari - 208 (+7)
- Google Chrome - 197 (+7)
- Microsoft Internet Explorer - 27 (+0)
- Mozilla Firefox - 139 (+4)
- Opera - 159 (+7)
As you can see Safari took the lead followed closely by Chrome. Opera and Firefox rounded out the middle while IE ended up in last place. The full score breakdown for each browser is posted below.
