HiSilicon Kirin 970 vs HiSilicon Kirin 990 5G

HiSilicon Kirin 970

The HiSilicon Kirin 970 is an ARM based high-end octa-core SoC for smartphones and tablet, which was introduced with the Huawei Mate 10 in late 2017. Besides 8 CPU cores (4x Cortex-A73, 4x Cortex-A53), the SoC is also equipped with a modern Mali-G72 MP12 graphics adapter, a dual-channel LPDDR4 memory controller as well as an LTE (4x4 MIMO, 5-band-carrier-aggregation, QAM-256, up to 1.2 Gbit/s) modem.

The performance cluster is clocked at up to 2.4 GHz and the four A53 power saving cores with up to 1.8 GHz. The performance should improve by about 20 percent according to Huawei and the power consumption reduced by 20 percent.

On the chip HiSilicon also included a dedicated Neural Processing Unit (NPU) for running machine learning tasks very efficiently compared to the CPU cores.

HiSilicon Kirin 990 5G

The HiSilicon Kirin 990 5G 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 2.36 GHz and finally the power saving cluster contains four small ARM Cortex-A55 cores with up to 1.95 GHz. Furthermore, the SoC integrates a neural processor (2 + 1 cores) for AI tasks and a ARM Mali-G76 MP16 GPU clocked at up to 700 MHz. Compared to the 4G version, the 5G Kirin 990 integrates a Balong 5G modem and is slightly higher clocked (2 of the 3 clusters and the GPU).

The Kirin 990 5G is produced in the modern 7nm (7FF+ with EUV) process at TSMC, the 4G version is still produced in the slightly older 7nm process as the Kirin 980.
