The power house of Apple's new iPhone 5 is the A6 chip featuring a dual-core processor with PowerVR SGX 54MP3 graphics unit. The processor is said to be running with a clock speed at 1.3GHz.
Apple boasts the A6 chip is designed to maximise performance while consuming less power. It possesses twice the processing power as well as graphics capabilities over the A5 chip used in iPhone 4S.
The A6 chip is said to be first SoC (System on Chip) to feature Apple designed CPU cores and it is second Apple SoC to be built using Samsung's 32nm LP High-K and Metal Gate transistors. Now a range of benchmark tests based on performance conducted by AnandTech reveal that the iPhone 5 with its dual-core A6 processor is indeed powerful when compared to its predecessor as well as to the rival high-end smartphones.
In both BrowserMark (measures browser performance) and Geekbench 2 benchmark tests (measures the performance) the iPhone 5 scored highest points beating other iPhones including iPhone 4S, iPhone 4 and iPhone 3GS.
There are indeed some interesting results in the final two performance benchmark tests-SunSpider and BrowserMark-wherein the iPhone 5 was tested against more than two dozens of high-end smartphones. As the benchmark results suggests in both the tests iPhone 5 topped the chart defeating all the other rival smartphones including RAZR i, Galaxy S3 (international and US variants), HTC's all three One series phones (One X, One S and One V), Evo 4G LTE, Galaxy S2 LG Optimus G and Galaxy Nexus.
