Smartphone vs PC – Javascript Benchmarks

I wanted to get a real comparison of where the current fastest smartphones are in terms of performance vs PCs I have available to test. Will update as I receive new figures from friends and/or new phones to test!

I found two javascript benchmarks, one called ‘SunSpider‘ from WebKit.org … the other ‘v8‘ from Google.

Here are the SunSpider results in milliseconds (less is better):

• [Smartphone] iPhone 4 with iOS 4 – 67
• [Smartphone] iPhone 3GS with iOS 4.3.5 – Crashed

Some interesting conclusions from the above:

• Javascript performance is about the software as much as the hardware – hence standard HTC Sensation being slower than a Nexus One in both tests! HTC Sense is probably to blame … Opera Browser far better! Also iPhone 3GS better than iPhone 4 running an older version of iOS!
• The Sony Vaio’s processor has roughly 3 times the performance of the Dell XPS Gen 4, but only ~double the performance in the benchmarks (is Vista to blame?)
