The iPhone 5's A6 processor appears to be roughly twice as fast as any chip in an existing iOS product, if results posted by Geekbench prove to be accurate.
If these iPhone 5 benchmarks are legitimate, they would match Apple's claims. "With the new A6 chip, just about everything you do on iPhone 5 is noticeably faster -- up to twice as fast compared with the A5 chip," Apple states on its iPhone 5 features page.
Geekbench results point to a 1GHz clock speed, an increase from the A5's 800MHz. Because that's not a huge jump in the chip's frequency, chip review site Anandtech said some of that extra performance may come from doing more instructions per clock cycle.
In short, if the chip is more efficient at processing instructions, it adds performance irrespective of clock speed.
The A6 chip is also thought to be the first Apple chip made on Samsung's new 32-nanometer manufacturing process. Typically when a chip moves to a more advanced manufacturing process, it gets faster and/or more power efficient -- or both.
For reference, the Samsung Galaxy S III with a Samsung Exynos 4412 quad-core chip rated at 1.4GHz landed at the top of Android benchmarks.
