The publication credited Apple for designing four of its own chips last year, which allows it to "control its own destiny" and create "the most compelling consumer-electronics experiences," including the A10 Fusion chip in iPhone 7, W1 chip in AirPods, T1 chip in the MacBook Pro with Touch Bar, and S2 chip in the Apple Watch Series 2.
"We pick the projects where we feel like we can make a difference—the big customer-impacting features," says Anand Shimpi, who works on hardware technologies at Apple. So the stunning depth-of-field effect from the iPhone 7 camera? That’s directly enabled by the new A10 chip. "The actual production of the stored portrait image is because of things that we put into the [image signal processor]," Shimpi says.Each chip has resulted in technological breakthroughs for Apple. The W1 chip in AirPods, for example, is programmed to automatically route the audio to each earphone, and engage the microphone, while its low power usage results in industry-leading battery life up to five hours on a single charge.
The S2 chip in Apple Watch Series 2 models results in performance improvements without sacrificing battery life, and the four-core A10 Fusion chip in the iPhone 7 and iPhone 7 Plus is up to two times faster than the A8 chip in the iPhone 6 and delivers the longest battery life—up to two hours longer—of any iPhone ever.
