Web Browsing and Javascript Performance

Next up, we have some numbers from the SunSpider JavaScript and Browsermark web-browsing benchmarks.

SunSpider JavaScript Benchmark
JavsScript Performance Testing

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.

All of the systems were tested using the latest version of Internet Explorer 10, with default browser settings, on a clean install of Windows 8.

The A4-5000 once again handily outruns the Atom-based Z2760 in the Sunspider benchmark, but the similarly-clocked Core i3-2377M puts up the best score of the group by far.

We see the same performance trend in the BrowserMark test (please note, all systems were tested with IE 10 in desktop mode). The A4-5000 is much faster than the Atom here, but the Core i3 once again takes the top spot.
