Apple's A9 processor for the iPhone 6S was 70 percent faster than the A8 before it, and designed to be "desktop-class performance." Apple is now introducing the A10 Fusion today, with the new iPhone 7. The new chip has four cores in total, and two cores that are high-performance cores. It's designed to be 40 percent faster than the A9 chip in the iPhone 6S, and twice as fast as the A8. Apple's Phil Shiller revealed that the new A10 fusion is 120 times faster than an original iPhone.
While there are two cores that run at high-performance mode, the other two are designed for low-power apps to be run efficiently. Everything is automatically controlled by a new power controller. Graphics performance has also been improved, and Apple is promising "console level gaming" as a result. Inside the new A10 Fusion is a 6 core graphics chip that's 50 percent faster than A9 found in the iPhone 6S, and three times faster than the A8 in the iPhone 6. Apple claims the new A10 Fusion is "the most powerful chip ever in a smartphone."
Perhaps the most important new feature of the A10 Fusion for iPhone users is battery life. Apple says the new chip lets the iPhone 7 last more than two hours more than the iPhone 6S, making it the "longest battery life ever in an iPhone."
