Chip in new iPhone 5 has been clocked at 1.3GHz by a new version of iOS benchmarking software Geekbench, faster than the 1.02 GHz previously reported. The silicon powering the new iPhone 5 appears to be more powerful than previously thought. The A6 processor found in Apple’s next-generation smartphone has been clocked at 1.3GHz by a new version of iOS benchmarking software Geekbench, faster than the 1.02 GHz previously reported . The new version of Geekbench, which landed today at the App Store, “features a dramatically improved processor frequency detection algorithm, which consistently reports the A6′s frequency as 1.3GHz,” Primate Labs John Poole told Engadget.
Earlier results posted by Geekbench suggested the A6 was roughly twice as fast as any chip in an existing iOS product, beating the dual-core A5 and A5X processors in the iPhone 4s and third-generation iPad (Retina), respectively. However, Poole said the previous software version wasn’t measuring the clock speed properly. ”Earlier versions of Geekbench had trouble determining the A6′s frequency, which lead to people claiming the A6′s frequency as 1.0GHz as it was the most common value Geekbench reported,” he said The new results appear to support Apple’s claims that the A6 is “up to twice as fast compared with the A5 chip.” Thought to be the first Apple chip made on Samsung’s new 32-nanometer manufacturing process, the A6 is more efficient at processing instructions. Chips moving to a more advanced manufacturing process tend to benefit by exhibiting faster speeds and more efficient power usage.

Intel appears to have taken a significant step toward competing in the mobile space.
The chip company is showing off its Rosepoint project at ISSCC this week. This is a 32nm system-on-chip (SoC) design that puts a dual-core Intel Atom processor right next to a digital Wi-Fi radio. Compared with the typical analog Wi-Fi chips that are available now, Intel claims that its digital version can be miniaturized more easily. It will also cost less to shrink them to fit mobile devices.
This breakthrough didn’t come easy because wireless radios and processors both emit radiation that tend to interfere with each other. As a result, Intel had to invent new radiation-shielding and noise-canceling methods to enable both components to exist on the same chip. The company is also looking into adding a digital cellular radio chip in the near future.
Such developments could eventually lead to smaller and more power-efficient mobile chips that will also cost less to manufacture, though Intel isn’t expecting this technology to reach the market for at least another three years.
