Faster and more efficient.
With an all-new four-core design, the A10 Fusion chip’s CPU has two high‑performance cores and two high‑efficiency cores. The high‑performance cores can run at up to 2x the speed of iPhone 6, while the high‑efficiency cores are capable of running at just one-fifth the power of the high‑performance cores. That means you get the best performance and efficiency when you need it.
