A6 makes iPhone 5 among first devices to ship with A15
The A6 processor Apple showed off yesterday in revealing the iPhone 5 is said by some analysts to be a Samsung-produced dual-core Cortex-A15. EETimes cites analysts at Nomura Equity Research in claiming that the device was manufactured using Samsung's 32-nm HKMG process, making Apple among the first device manufacturers to introduce a processor based on ARM's low-power Cortex-A15 design, which was introduced two years ago.
Apple provided few technical specifications on the chip powering the new iPhone, opting instead to focus on broader descriptions of its performance, but those performance details appear to match what analysts would expect out of a device with the Cortex-A15 at its core.
If indeed the iPhone 5 contains a Cortex-A15, its A6 chip is likely based on Samsung's Exynos 5250 design. Samsung began testing the Exynos 5250 late in 2011, and the design had been expected to begin shipping in volume in the summer of this year. The Exynos 5250 has a 2GHz clock frequency and is said to double the performance of the previous Exynos, which was based on the 1.5GHz Cortex-A9. In detailing the iPhone 5's internals, Apple pointed out that the A6 chip provided twice the CPU and graphics performance of the A5x that powered the iPhone 4S.
