Results: HTML5 And JavaScript Benchmarks
The tests on this page are JavaScript- and HTML5-heavy selections from our Web Browser Grand Prix series. Such tests are extremely meaningful to mobile devices because so much of the in-app content is served via the platform's native Web browser. These tests not only offer a view of each device's Web browsing performance, but since these tasks are traditionally so CPU-dependent, browser benchmarks (especially JavaScript-heavy tests) are a great way to measure SoC performance among devices using the same platform and browser.
Browsermark 2.1
Rightware's Browsermark 2.1 is a synthetic browsing benchmark that tests several performance metrics, including load time, CSS, DOM, HTML5 Canvas, JavaScript and WebGL.
The G3 performs as expected in our first Web browsing benchmark, achieving nearly the same score as the OnePlus One and Galaxy S5. The Snapdragon 805-powered Note 4 is only 6% faster than the G3, which is not enough to be noticeable in everyday use.
JSBench
Unlike most JavaScript performance benchmarks, JSBench could almost be considered real-world, since it utilizes actual snippets of JavaScript from Amazon, Google, Facebook, Twitter and Yahoo.
Again we see the Snapdragon-based devices line up according to CPU architecture. The iPhone 6 Plus dominates this benchmark thanks to Safari’s JIT compiler optimizations.
Peacekeeper 2.0
Peacekeeper is a synthetic JavaScript performance benchmark from Futuremark.
The Peacekeeper results are similar to those from JSBench. So far, the G3 performs on par with its peers, avoiding any performance anomalies.
WebXPRT 2013
Principled Technologies' WebXPRT 2013 is an HTML5-based benchmark that simulates common productivity tasks that are traditionally handled by locally installed applications, including photo editing, financial charting and offline note-taking.
The LG G3 performs well in our final Web browsing benchmark and doesn’t exhibit any performance or stability issues.
