Benchmark results purportedly from the iPhone 5 have surfaced which show the A6 chipset in indeed much faster than any previous Apple processor. An overall Geekbench score of 1601, if legit, is also reportedly faster than the average score of all Android phones that have run the benchmark.
Individually, the iPhone 5 scored a 1220 in the integer test, 2051 in the floating point category, returned a memory score of 1811 and a stream score of 944. John Poole of PrimateLabs points out that the iPhone 4S has an average Geekbench score of 629 while the iPad 3's average is just 766. 9to5Mac notes the Tegra-3 powered Nexus 7 tablet turned in a score of 1591 while Samsung's flagship Galaxy S III smartphone scored 1560. The S III running Android 4.1 Jelly Bean still outperforms the iPhone 5, we hear.
The handset in question was running iOS 6.0 with an ARMv7 SoC clocked at 1.02GHz - a dual-core chip that comes bundled with 1GB of RAM. It was revealed over the weekend that the A6 was designed by Apple specifically for the iPhone 5. The chip isn't based on an A9 or A15 design which means that Cupertino was able to prioritize performance and power specifically for iOS.
These results should be taken with a grain of salt, however, as it's relatively easy to fake Geekbench results. For what it's worth, Poole believes the results are legitimate but we won't know for sure until the handset hits the streets on September 21.
