HiSilicon Kirin 9000 vs MediaTek Dimensity 920

HiSilicon Kirin 9000

The HiSilicon Kirin 9000 is an ARM based high-end octa-core SoC for smartphones and tablet, which was introduced with the Huawei P40 Pro. It integrates eight CPU cores in three clusters. A single high performance ARM Cortex-A77 cores with up to 3.13 GHz for fast single core performance. Three more performance cores (same Cortex-A77 architecture) with up to 2.54 GHz and four efficiency cores based on the ARM Cortex-A55 architecture with up to 2.05 GHz. All 8 cores can be used at once (big.LITTLE).

The integrated graphics card is using the Mali-G78 architecture and features all 24 cores (G78MP24).

For AI acceleration (NPU), the Kirin 9000 integrates the Da Vinci Architecture 2.0 (2 * Ascend Lite and 1 * Ascend Tiny). Huawei specifies 8 MB of system cache (most likely shared for CPU, GPU and AI) and can access LPDDR4X and LPDDR5 main memory. The integrated 5G modem supports SA&NSA, Sub-6G and mmWave. WiFi 6 including VHT160 and Bluetooth 5.2 are also integrated in the chip.

The CPU performance is in the top tier of mobile SoCs of 2020 and slightly above the Snapdragon 865+ and on a level with the older Apple A13 Bionic SoC.

The Kirin 9000 is produced at TSMC in the modern 5nm process.

MediaTek Dimensity 920

The Mediatek Dimensity 920 is a fast mid-range SoC with an integrated 5G modem. It includes two fast ARM Cortex-A78 cores at up to 2.5 GHz and six power efficient Cortex-A55 cores at up to 2 GHz (Octa-Core with Heterogeneous Multi-Processing). Furthermore, the chip integrates a 4 core ARM Mali-G68 MC4 GPU, a Wi-fi 6 modem, a LPDDR4x memory controller, a AI processing unit  and video de- and encoding.

The 5G modem supports Sub-6 GHz and dual SIM. The download speeds can reach up to 2.7 Gbit/s.

Compared to the older Dimensity 900, the 920 offers slightly higher clock speeds for the CPU and GPU.

The Dimensity 920 is manufactured in the modern 6nm process and should be very power efficient.
