The SunSpider Javascript benchmark measures the browsing performance of mobile devices and is applicable for all mobile platforms. It not only takes into consideration the underlying hardware performance of a device, it also assesses how optimized a particular mobile platform is to deliver a high-speed web browsing experience. It is important to note that for this benchmark, a lower score means a better web browser performance of a mobile device.

The Air and Surface 2 tied for the top spot in the SunSpider Javascript while the Tab Pro 10.1 fared the worst.
