One of the important hardware aspects of the recently launched iPhone 6 and iPhone 6 Plus from Apple is the A8 processor chip. In fact, a processor chip or some might called it the SoC (System on a Chip) is the more important component in a smart phone nowadays since it can either break or make the device. In this article, we explain further about Apple’s new processor chips.
Apple A8’s Processor Technology
The processor chips which powered the previous generation of iPhones were manufactured by Samsung on behalf of Cupertino. However, the latest A8 chip was not manufactured by the South Korean-based company; instead it was manufactured by TSMC (Taiwan Semiconductor Manufacturing Company).
Although there is no confirmation about the clock rate of the A8 chip, but based on some preliminary benchmark result, it shows that the chip is the second generation of dual-core Cyclone processor, possibly ticking at 1.4GHz. In comparison, the iPhone 5S is also running on dual-core CPU but it is of lower clock rate – 1.3GHz. One thing that is confirmed is that the A8 SoC is based on ARMv8-a architecture which makes it a 64-bit, similar to A7 chip on iPhone 5S.
Apple A8’s Graphic (GPU)
Another important chip of iPhone 6 and iPhone 6 plus is the Graphic Processing Unit (GPU) chip. This chip controls the processing of the image display to the screen. Although there is no confirmation from Apple too, we speculate that both smart phones are using PowerVR GX6650 GPU unit. The chip is one of the manufacturer’s most efficient GPU.
Apple A8’s motion co-processor – M8
The M8 chip in iPhone 6 and iPhone 6 Plus is the next generation of M7 in iPhone 5S. The chip mainly collect information based from the sensors such as the accelerometer, the compass, etc. Improvement in M8 version includes the enhanced barometer (to monitor air-pressures), step-counting, various elevation changes and total distance travelled. It is also able to sense whether you are stationary or moving. These are a few of the usage among the other usage of the chip.
Apple A8 and iSight camera
The new iPhone 6 and iPhone 6S will come with a new fancy feature such as Focus Pixels, a better face detection and continuous auto-focus. The collaboration between Apple A8 and iSight will result in images with less noise and better quality.
Apple Battery Life
Although it is not significant but the battery life plays an important role in deciding whether a smart phone is considered good. Despite the deep optimization on hardware and software, the iPhone 5S with its 1570mAh battery does not top the performance. However, with the new A8 chips which boast of its power efficiency, hopefully will give a better battery life to iphone 6 and iphone 6 Plus. iPhone 6 with bigger 1800mAh battery size while iPhone 6 Plus with 2915 mAh battery size.
