Industry-level trade feasibility studies

iPhone6 chip: mobile phone chip with excellent performance iPhone6 is Industry-level trade feasibility studiesa classic mobile phone released by Apple in September 2014. It not only makes a lot of appearance design Improvement also has a unique advantage in mobile phone chips.iPhone6 is equipped with the A8 chip designed by Apple, which has excellent performance and energy efficiency ratio, providing solid support for the excellent performance of iPhone6. First of all, the A8 chip has excellent performance in terms of processor. This chip adopts the second-generation 64-bit architecture, is equipped with 200 million transistors, and is manufactured by TSMC's 20nm process. These features make the processor of the A8 chip have a higher clock frequency and faster running speed. In the actual test, the single-core performance of the A8 chip processing unit equipped with iPhone6 is about 25% better than that of the A7 chip of iPhone5S. At the same time, the A8 chip also uses a lot of CoreMotion collaborative processors developed by Apple itself. This co-processorThe device can monitor all sensors such as accelerometers, gyroscopes and compasses, and process the data flow generated by them through hardware. In this way, when running various applications on iPhone6, the A8 chip can avoid the inefficiency problem that too many hardware tasks affect CPU performance through intelligent processing of sensor data, making the response speed of the application faster. Secondly, the graphics performance of the A8 chip is also excellent. Apple has equipped the A8 chip with a new generation of Metal graphics API, which allows developers to use GPU resources more directly in applications such as games. In the actual test, the GPU performance of the A8 chip is more than 50% better than that of the A7 chip of iPhone5S when testing standard test software such as the application glBenchmark 2.7 and 3D Mark.This excellent graphics performance makes the image processing and game experience of iPhone6 excellent, smooth and natural without distortion. Finally, the A8 chip also has a good energy efficiency ratio. Compared with the previous A7 chip, the manufacturing process of the A8 chip is smaller and the power consumption is also reduced. At the same time, the coprocessor can also process sensor data more accurately, which greatly reduces the power consumption of iPhone6. In the actual test, the iPhone6 can reach about 11 hours of battery life to watch videos with the A8 chip, which is greatly improved compared with the previous iPhone5S. In general, the A8 chip is a mobile phone chip with excellent performance. The chip has extremely high processing performance and excellent energy efficiency ratio, which makes the iPhone6 have a more excellent performance. Through continuous pursuitAnd innovation, the future mobile phone chip technology will definitely become more and more advanced, bringing us a better user experience.
