The fastest SunSpider test recorded on a smartphone today is 914.7 milliseconds, AnandTech confirms. The score belongs to the elusive Apple iPhone 5, based on the A6 dual-core system-on-a-chip (SoC).
The SunSpider 0.9.1 run on the iPhone 5 has churned up an impressive result of 914.7 milliseconds, which is considerably faster than any device out there, including the Samsung Galaxy S III, as well as the Lava XOLO X900 based on Intel’s Atom architecture. Highlighted
, the benchmark results reveal that “Apple specifically targeted improvements in the memory subsystem when designing the A6's CPU cores.”
The A6 has a substantially better cache/memory interface than ARM's Cortex A9, according to the hardware review buffs, who add that "The result is the fastest SunSpider test we've ever recorded on a smartphone - faster even than Intel's Atom Z2460."
According to webkit.org
“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.”
SunSpider runs each test multiple times to determine an error range and then a comparison mode is also offered to determine if the difference is negligible or not.
The current SunSpider version is 0.9.1. You can access it here
