HiSilicon Kirin 990 vs HiSilicon Kirin 820 vs HiSilicon Kirin 980

HiSilicon Kirin 990

The HiSilicon Kirin 990 4G is an ARM based high-end octa-core SoC for smartphones and tablets, which was introduced with the Huawei Mate 30 Pro in late 2019. It integrates eight CPU cores in three clusters. The performance cluster contains two Cortex-A76 cores with up to 2.86 GHz, the balanced cluster contains also two Cortex-A76 cores but with only up to 2.09 GHz and finally the power saving cluster contains four small ARM Cortex-A55 cores with up to 1.86 GHz. Furthermore, the SoC integrates a neural processor (1 + 1 cores) for AI tasks and a ARM Mali-G76 MP16 GPU clcoked at up to 600 MHz. Compared to the 5G version, the 4G Kirin 990 integrates a fast 4G modem and is slightly lower clocked (2 of the 3 clusters and the GPU).

The Kirin 990 is produced in the modern 7nm process at TSMC.

HiSilicon Kirin 820

The HiSilicon Kirin 820 is a ARM-based mid-range Octa-Core-SoC for Android based smartphones and tablets. It was announced mid 2020 and contains 8 processor cores. One fast ARM Cortex-A76 core with up to 2.36 GHz, three addition A76 cores at up to 2.22 (as the old Kirin 810) and four efficiency Cortex-A55 cores at up to 1.88 GHz. Furthermore, the SoC integrates a 5G modem and a fast mid-range ARM Mali-G57 MP6 graphics card. For AI acceleration, the Kirin 820 integrates a DaVinci NPU.

The performance of the CPU part in our tests was slightly higher than the old Kirin 810 (thanks to the fast performance core). Huawei advertises 27% performance advantage for the CPU. The NPU and GPU have bigger performance gains with 73% and 38% more power.

The chip should also integrate Bluetooth 5 and WiFi 6.

The SoC is manufactured in the modern 7nm process at TSMC and therefore should be very energy efficient.

HiSilicon Kirin 980

The HiSilicon Kirin 980 is an ARM based high-end octa-core SoC for smartphones and tablets, which was introduced with the Huawei Mate 20 Pro in late 2018. It integrates eight CPU cores in three clusters. The performance cluster contains two Cortex-A76 cores with up to 2.6 GHz, the balanced cluster contains also two Cortex-A76 cores but with only up to 1.92 GHz and finally the power saving cluster contains four small ARM Cortex-A53 cores with up to 1.8 GHz. Furthermore, the SoC integrates a modern LTE radio with Cat 21/18 (max. 1400 Mbps download, 200 Mbps upload), 2x faster dual ISP (versus 970), a LPDDR4X 2133 MHz memory controller (34.1 GB/s versus 29.9 GB/s of the Kirin 970) and a 2160p30 H.265 video encoder (2160p60 decoding). The Kirin 980 is produced in the modern 7nm process at TSMC as the first Android SoC (after the Apple A12).
