Last year, Apple introduced the groundbreaking 64-bit A7 processor for the iPhone 5S. Not surprisingly, Apple’s upcoming iPhone 6 models are widely expected to introduce the next-generation A-series chip that has already been dubbed the “A8” processor. However, a new rumor out of Asia suggests that the A7 processor won’t be the only chip that is upgraded in the next iPhone models.
According to recently leaked Apple schematics obtained by Chinese repair company GeekBar and highlighted by GforGames, the next-generation iPhone models will also include a new coprocessor that will replace the current M7. As you may recall, besides including the 64-bit processing functionality of the A7, the system-on-a-chip (SoC) package in last year’s iPhone 5S also introduced a non-A-series chip called the M7 motion coprocessor. According to schematics uncovered by GeekBar, the next-generation coprocessor is codenamed “Phosphorus.” GeekBar speculated that it will likely be used to process new types of health-related data for the Health app and HealthKit data storage platform that was unveiled at this year’s Worldwide Developers Conference.
It should be noted that the current M7 coprocessor already continuously detects and records motion data using an accelerometer, a gyroscope, and a compass. This data enables various health and fitness apps to run on the iPhone 5S, such as apps that keep track of a user’s total steps. When the M7 chip was first announced, several industry watchers noted that the motion-sensor chip would be ideal for use in a wearable tech product with health-monitoring capabilities, such as the long-rumored iWatch. However, now it appears that Apple will be implementing an even more powerful motion coprocessor in the iPhone 6. Although the coprocessor is currently referred to by the Phosphorus codename, it is likely that the chip will follow Apple’s typical naming conventions and be called the M8.
