Every generation of iPhone ships with a new processor and the iPhone 6s/6s Plus are no different; they are powered by an A9 processor. However, the A9 chipset is found to come in two different sizes.
According to Chipworks, the A9 chipsets are built by Samsung and TSMC. Further investigations reveal that the A9 chipset built by Samsung is 10% smaller than the one built by TSMC. On paper, a smaller die size is more power efficient.
Will an iPhone 6s powered by the Samsung-built A9 chipset perform better? Chipworks is in the process of conducting further testing and we will know the results soon.
