Asus ZenBook UX305CA Review: Thin And Light, Great Battery Life

Benchmarks: SunSpider and PCMark 8

These first benchmarks are the most important in evaluating the Asus ZenBook UX305CA’s value. The tests help us gauge the ultrabook’s ability to handle everyday computing tasks, including Web browsing, video chatting and word processing.

SunSpider JavaScript Benchmark
JavaScript Performance Testing

SunSpider is a well-known JavaScript benchmark. The test is designed for comparing browsers to each other, so it’s worth pointing out that different Web browsers can have an impact on scores.


We used Windows 10’s default Web browser, Microsoft Edge, to run SunSpider. Microsoft’s newest browser received better JavaScript support from Microsoft last summer. Still, the system trailed several of the ultra-slim, but more powerful systems in our comparison pool.

PCMark 8
Productivity and System-Level Benchmarking

We selected three tests from PCMark 8. The Home test is just as it sounds: a collection of everyday tasks, including web browsing and chatting. The Work test is more demanding and has business-oriented tests, while the Storage test gives you a close-up look at what your SSD or hard drive can do.


Here, the Asus ZenBook UX305CA redeemed itself. It offered solid scores in all three categories, but really shined in the Home and Work tests. We used the Accelerated versions of the both the Home and Work tests on all of the systems in this comparison pool. The ZenBook’s performance here is rock solid and its SSD proves to be fairly speedy, too.
