Apple’s A-Series processor has been at the top of the world in recent years, and its design and performance are absolutely outstanding. The latest A14 is no exception. Icmasters, a semiconductor reverse engineering and IP service organization, recently put an apple A14 under a microscope and observed the monster carefully. < p > < p > Apple A14 is manufactured by TSMC 5nm process, which integrates as many as 11.8 billion transistors. The core area is only 88 square millimeters, and the density is 134 million transistors per square millimeter. < / P > < p > for comparison, the previous generation A13 used TSMC 7Nm process, integrated 8.5 billion transistors, with a core area of 94.48 square mm and a density of 89.97 million transistors per square millimeter. < p > < p > the earlier A12 is also TSMC 7Nm process, integrating 6.9 billion transistors, with a core area of 83.27 square mm and a density of 82.86 million transistors per square millimeter. < p > < p > according to TSMC’s propaganda, the 5nm process can achieve a density of 171.3 million transistors per square millimeter, and apple A14 is far from the theoretical value, which is less than 80%. < / P > < p > of course, this is not to say that the 5nm process of TSMC is not good, but different chips have different logic circuits, cache layout and design. However, compared with the theoretical value, the actual value is much lower this time. The previous generations have all exceeded 90%, and the A13 has even reached an amazing 98.65%. In addition, microscopic observation can clearly see six CPU cores in A14, including two big cores firestorm, three small cores icestorm, four GPU cores and 16 neural engine cores. < / P > < p > from the perspective of splitting, the GPU core occupies 11.65 square mm, the second level cache of two large cores consumes 9.1 square mm, and the second level cache of four small cores only takes up 6.44 square millimeter.
