Apple has not overstated the performance of the iPhone, but the performance results of each test have made the Android camp look. The iPhone 6S is still no exception, and the A9 easily defeated the eight cores with dual-core. Now, the foreign media Chipworks sent out the initial disassembly of the A9 processor, and got several important information points: 1. The A9 CPU is dual-core and the GPU is six-core; 2, iPhone 6S built-in 2GB RAM, suppliers are Hynix and Toshiba; 3. A9 is based on the 14nm process. Now the point is, the A9 processor uses a 14nm process (codenamed APL0898), at least this is what Chipworks got. According to the previous report, the processor also has a 16nm process version (TSMC foundry processor). The number is APL1XXX, and Samsung is APL0X98/5X98). The size of A9 is 8.7 & TImes; 10.7 = 94 square millimeters, while the size of A8 is 12.5 & TImes; 10mm = 125 square millimeters, the size is reduced by nearly 75%, which is definitely the credit of 14nm process. The A9 processor is still a native dual-core design, the same as the A8, and the previous Geekbench test shows that the best processor in the A9 single-core performance kill Android phone is the Samsung Exynos 7420, and the multi-core performance is basically the same. On the GPU side, the A9 is not a custom eight-core, but a six-core, and from the actual performance test, it is equal to the A8X custom eight-core GPU PowerVR GXA6850, most likely the PowerVR Series7XT series. Compared to the A8, the A9's SDRAM cache (level 3 cache) seems to increase from 4MB to 8MB, while it may provide 3MB of L2 cache.
