Noticeably faster performance and graphics that feel more true to life. That’s the perennial goal when creating a new mobile chip. But performance shouldn’t come at the expense of efficiency. Poor battery life for the sake of speed is never an option with iPhone. Which is why we engineered an all-new chip and an all-new coprocessor for iPhone 5s: A7 and M7.
The A7 chip is designed around 64-bit architecture — a first for any smartphone. The move to 64-bit has been years in the making. But we did it because we wanted to put desktop-class processing power in the palm of people’s hands. Just imagining what people will do with that made the decision to invest in it an easy one. The A7 chip gives iPhone 5s the power it needs for all the capabilities it now possesses. It’s up to 2x faster than the previous generation in both CPU and graphics performance. It has an all-new image signal processor. And it supports OpenGL ES 3.0, enabling visual effects previously possible only on computers and gaming consoles. Yet with all these performance enhancements, A7 is still energy efficient.
The new M7 coprocessor is designed to make iPhone 5s even more efficient. It offloads work from the A7 chip by collecting motion data from the accelerometer, gyroscope, and compass. Apps can then use this data without constantly engaging the A7 chip. Because M7 is engineered for this specific task, it uses significantly less power than A7 would require. So again, battery life is spared.
