Other iOS products see modest improvement under iOS 6
The iPhone in fact surpassed the mark easily, completing the suite of tests in just 914.7 milliseconds, far ahead of the second-place finisher, Lava's XOLO X900 (which had a score of 1,279.4. Third place was captured by what many see as the iPhone's chief rival, the Samsung Galaxy S III (international version), which scored 1,442.9 (the US version scored much lower at at around 1,800 (averaged between the AT&T and T-Mobile versions).
Somewhat surprisingly, the iPhone 5's A6 outperformed the XOLO's "Medfield" single-core Atom Z2460 processor, which runs at 1.6GHz. The iPhone 4S and other smartphones that run on chips based on ARM's Cortex A9 SoC had routinely done very poorly compared to the Atom, with Intel suggesting that memory subsystem issues were the culprit (the iPhone 4S scores 2,250 on the SunSpider test for comparative purposes).
Apple's A6 is the company's first truly custom-designed chip, though it does use some elements of ARM's Cortex A15 but builds from there. Clearly, memory bandwidth and cache was an area of customization for the A6, reports Anandtech. The use of the SunSpider software is necessitated by its compatibility with iOS and other platforms; the well-regarded SPECint does not yet have an iOS version.
The A6 has also been seen to perform remarkably well in Geekbench tests, with authentic results above 1,600, beating even the quad-core Samsung Galaxy S III (though numerous faked scores have been submitted to contest the result following publicity of the iPhone 5's superior score). Reviews have singled out the improvement in speed on both CPU and graphics tasks on the chip, which Apple says is twice as fast as the one in the iPhone 4S. Apple has not yet released its own testing of processor scores compared to any rival phones. [via Anandtech]
