The a15. The A15 processor integrates up to 15 billion transistors, an increase of 3.5 billion compared with 11.5 billion in the previous generation, that is, a full 30%, and the manufacturing process is still TSMC 5nm. The CPU part is still 6 cores, 2 high-performance large cores and 4 energy-efficient small cores, claiming to be 50% ahead of the competitive character, and the GPU is upgraded from 4 cores to 5 cores. Naturally, the neural engine must be upgraded, with a computing power of 15.8 trillion times per second, which is 34% faster than the previous generation, and can smoothly run powerful CoreML and AR modeling. The Kirin 990 processor will be manufactured using TSMC's second-generation 7nm process.
