“For quite some time, Apple has been cranking out one crazy-impressive mobile processor after another,” Ashraf Eassa writes for The Motley Fool. “This year’s A10 chip, unsurprisingly, contains the fastest processor cores ever crammed into a smartphone — bar none. The processor performance of even Apple’s prior-generation A9 has yet to be matched by any other mobile processor maker.”

“Until now, it was something of a mystery as to whether Apple’s high-efficiency cores were an internal Apple design or simply an off-the-shelf, low-power processor like ARM Holdings’ Cortex A53,” Eassa writes. “Thanks to some work done by the Linley Group (via Barron’s), that mystery is now solved.”

“The Linley Group says that Apple’s high-efficiency core is a processor that Apple has codenamed Zephyr. The core is quite small, taking up just 0.78 square millimeters of area on the A10 processor (much smaller than Apple’s high-performance Hurricane core found on the same chip), though the Linley Group says it’s a bit larger than ARM’s Cortex A53 (but I’d imagine that it’s more powerful as well). What’s interesting about Zephyr, though, isn’t necessarily its power or performance but instead the mere fact that it exists,” Eassa writes. “That Apple has designed an all-new processor core specifically to serve as a ‘high-efficiency’ counterpart to a high-performance core suggests that the company has built its processor/chip teams out even further.”
