iPhone 5 bests Galaxy S3, Intel Atom in SunSpider browser benchmark
A few days ago we looked at an unconfirmed Geekbench test – which was going to be confirmed later on – that revealed the A6 chip inside the iPhone 5 was faster than its counterparts in current high-end Android devices, and way faster than its predecessors.
The iPhone 5 beat the Galaxy S3 and the Nexus 7, although it’s worth noting that Samsung’s flagship smartphone was tested running Ice Cream Sandwich. Once Jelly Bean arrives to the high-end Android handset, the new iPhone will lose that top spot it currently occupies in that particular test.
According to AnandTech, the iPhone 5 scored 914.7ms in the test (lower is better) beating Intel-based Lava XOLO X900 and the quad-core Samsung Galaxy S3 version, which scored in the same test 1279.4ms and 1442.9ms, respectively. The iPhone 4S and iPhone 4 scored 2250 and 3545 in the same tests. The publication writes:
SunSpider is quickly outlasting its welcome as a smartphone benchmark, but it does do a great job of highlighting issues with the Cortex A9’s memory interface. Intel originally hinted at issues in the A9’s memory interface as being why Atom was able to so easily outperform other ARM based SoCs in SunSpider. As we surmised in our A6 Geekbench post, it looks like Apple specifically targeted improvements in the memory subsystem when designing the A6’s CPU cores. The result is the fastest SunSpider test we’ve ever recorded on a smartphone – faster even than Intel’s Atom Z2460.
This doesn’t tell us much about the A6’s architecture other than it’s likely got a better cache/memory interface than ARM’s Cortex A9.
We’ll probably see more benchmark comparisons in the future, especially between brand new Android devices, such as the upcoming Samsung Galaxy Note 2, and the new iPhone.
