Next up, we have some numbers from the SunSpider JavaScript benchmark. According to the SunSpider website:
This benchmark tests the core JavaScript language only, not the DOM or other browser APIs. It is designed to compare different versions of the same browser, and different browsers to each other. Unlike many widely available JavaScript benchmarks, this test is: "real-world, balanced and statistically sound."

The Surface 2 smoked the competition in SunSpider, posting a score of 395.5ms. Only the NVIDIA SHIELD (524.8) and Intel Atom Z3770 tablet (577.6) were within screaming distance of the Surface 2, and most mobile devices in our test bank weren’t even close--including the original Surface tablet, which was way more than twice as slow at 1044ms.

Although its performance in Rightware’s BrowserMark wasn’t as dominant as in SunSpider, the Surface 2 scored solidly in fourth place. Again, it beat the first-gen Surface, although not by as dramatic a delta.
