Google Nexus 5X Review: A Model Of Efficiency

Performance: Browsing and JavaScript

Next, we'll take a look at how the Nexus 5X compares to other smartphones by examining a few benchmarks that are currently available online or in the Android Marketplace. 

First, let’s take a look at the JetStream JavaScript benchmark, which has recently replaced SunSpider in our suite of browsing tests. According to the JetStream website:

JetStream is a JavaScript benchmark suite focused on the most advanced web applications. Bigger scores are better.

Given that SunSpider was recently decommissioned, it'll take some time to build up a database of devices tested with JetStream. Furthermore, JetStream puts mobile browsers through a fairly intense gauntlet of tests. Historically, Chrome (which is the default browser on Nexus devices) hasn't fared well in these tests, while Safari (the default browser within iOS) has. Hence the significant gap between the Nexus 6P/5X and Apple's iPhone 6s Plus. Still, everyday browsing is a pleasure on this device, with nary a hint of lag or stuttering.

In the JavaScript and web-browsing related BrowserMark tests, the Nexus 5X falls just slightly behind the latest duo in the Samsung Galaxy lineup, Apple's latest phablet, and the Snapdragon 810-equipped Nexus 6P.
