1 and Kirin 990 are a new generation of mobile phone processors developed by Huawei. Hisilicon Kirin 990 processor will be manufactured by TSMC's second generation 7 nm process. The overall performance of Kirin 990 processor will be improved by 10% compared with Kirin 980.

2. Kirin 990 is divided into 4G version and 5G version, and the architecture and performance are basically the same. The difference lies in the process, CPU frequency, number of NPU cores, and whether 5G baseband is integrated. Kirin 9905G is the first flagship chip in the industry to integrate 5GModem into SoC chip, which realizes the advantages of smaller area, lower power consumption and stronger performance, and supports NSA/SA dual architecture and TDD/FDD full band.
