Performance: Browsing and JavaScript

Next, we'll take a look at how the Nexus 6 compares to other tablets by examining a few benchmarks that are currently available online or in the Android Marketplace. 

First, let’s take a look at 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 - This test mostly avoids microbenchmarks, and tries to focus on the kinds of actual problems developers solve with JavaScript today, and the problems they may want to tackle in the future as the language gets faster. This includes tests to generate a tagcloud from JSON input, a 3D raytracer, cryptography tests, code decompression, and many more examples. There are a few microbenchmarkish things, but they mostly represent real performance problems that developers have encountered.

Balanced - This test is balanced between different areas of the language and different types of code. It's not all math, all string processing, or all timing simple loops. In addition to having tests in many categories, the individual tests were balanced to take similar amounts of time on currently shipping versions of popular browsers.

Statistically Sound - One of the challenges of benchmarking is knowing how much noise you have in your measurements. This benchmark runs each test multiple times and determines an error range (technically, a 95% confidence interval). In addition, in comparison mode it tells you if you have enough data to determine if the difference is statistically significant.

We're still building up reference data for the newest version of SunSpider, so we ran both v0.9.1 and v1.0.2 here. As you can see, the Nexus 6 returned relatively similar results in both versions of the test. In the past, we’ve noticed that the Chrome browser is typically slower than other browsers in this test. Since Chrome is the only browser that comes preloaded on the Nexus 6, we weren’t surprised to see scores that were middle-of-the road.

Rightware recently updated the BrowserMark benchmark to a version 2.1. Scores are not compatible with previous versions. For the sake of comparison, we ran the previous version of the BrowserMark benchmark. Using version 2.0, you’ll find the Nexus 6 in fourth place behind the Note 4, Galaxy S5 Sport, and iPhone 5S.
