Same powerful chip as iPhone 6s
Engineered to bring desktop-class architecture to the iPhone, the 64-bit A9 chip delivers incredible performance and console-standard graphics in apps and games. Overall computing performance is improved by up to 70% over the previous generation, while graphics are as much as 90% faster, ensuring you get a more reactive, immersive experience. Built within the A9 chip is the M9 motion coprocessor, which is connected to the accelerometer, compass and gyroscope to improve city navigation and fitness tracking. It also works to strengthen your connection to Siri, so you don’t have to hold up your iPhone to ask your questions.
