HiSilicon Kirin 710A vs HiSilicon Kirin 820
HiSilicon Kirin 710A
► remove from comparison
The HiSilicon Kirin 710A is a ARM-based mid-range Octa-Core-SoC for Android based smartphones and tablets. It is based on the Kirin 710, but manufactured in 14nm FinFET at SMIC (China) versus the TSMC in 12nm. It was announced mid 2020 and contains 8 processor cores (4x Cortex-A73 at up to 2 GHz, 4x Cortex-A53 at up to 1.7 GHz, BigLITTLE), an ARM Mali G51 MP4, a dual-channel LPDDR4 memory controller and a LTE radio (600 Mbps down, 150 Mbps up). Therefore, the CPU part is similar to the Kirin 960 and 970 (both higher clocked), but the graphics card is a lot slower.
HiSilicon Kirin 820
► remove from comparison
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.
