Does HTML5 Really Beat Flash? The Surprising Results of New Tests

Mac Tests
* With Safari, HTML5 was the most efficient and consumed less CPU than Flash using only 12.39% CPU. With Flash 10.0, CPU utilization was at 37.41% and with Flash 10.1, it dropped to 32.07%
* With Google Chrome, Flash and HTML5 were both equally inefficient (both are around 50%)
* With Firefox, Flash was only slightly less efficient than in Safari, but better than in Chrome
Windows Tests
* Safari wouldn't play HTML5 videos, so there was no way to test that. However, Flash 10.0 used 23.22% CPU but Flash 10.1 only used 7.43% CPU
* Google Chrome was more efficient on Windows than Mac. Playback with Flash Player 10.0 was about 24% more efficient than HTML5, while Flash Player 10.1 was 58% more efficient than HTML5.
* On Firefox, Flash 10.1 dropped CPU utilization to 6% from 22% in Flash 10.0
* In IE8, Flash 10.0 used 22.41% CPU and Flash 10.1 used 14.62% CPU

Will Apple budge? At this point, it's unlikely. In blocking Flash on Apple devices, the company can easily claim that it's simply not an efficient technology...and that's true for now, considering how it's set up. But if the company wanted to allow it and make it work, it seems reasonable to believe that they could. This is what leads some insiders to believe that the decision to block Flash is less of a technological one and more of a business-minded one. After all, if you could easily visit Hulu.com to stream TV shows and movies, then why would you need to buy them from the iTunes Store?
So while Flash's "CPU hogging" may be a contributing factor in Apple's decision to not support the technology on their mobile devices, that's probably not the only reason behind the block...."
For what it's worth, from a practical standpoint, I can't tell much difference in real world conditions, and neither should most users with relatively current computers. |
The numbers are interesting but say not much about what performance would be on iPad/iPhone. Would be nice to see some numbers for other mobile devices.
Seems Adobe still has some work to tune up Flash on OS X. Or maybe the plugin architecture of Safari/Chrome/Firefox there is inherently hostile...
Would also be interesting to get some numbers for other multimedia plugins.
And of course there's probably a lot of variance with these numbers depending on how well endowed a particular system is.
