HiSilicon Kirin 920 vs Qualcomm Snapdragon 425 (MSM8917)

HiSilicon Kirin 920

The HiSilicon Kirin 920 is an ARM-based octa-core SoC (system-on-a-chip) for smartphones and tablets. It was launched in the second half of 2014 alongside and features four Cortex-A15 cores clocked at up to 1.7 GHz. Furthermore, there are four additional Cortex-A7 cores to save power, an ARM Mali-T628 MP4 GPU and a 2x 32 bit LPDDR3 memory controller. The integrated LTE Cat. 6 modem provides download speeds of up to 300 Mbps.

Qualcomm Snapdragon 425 (MSM8917)

The Qualcomm Snapdragon 425 (8917) is an ARM-based entry level SoC for tablets and smartphones (mostly Android based). It was announced in February 2016 and integrates four 64-Bit Cortex-A53 CPU cores (quad-core) that clock with up to 1.4 GHz. Furthermore, there is a Adreno 308 graphics card, a LPDDR3 memory controller (max. 667 MHz) and wireless radios for WiFi and 4G/LTE included in the chip.

The Cortex-A53 is the successor of the entry level Cortex-A7 CPU cores. The A53 is now capable of 64 Bit (ARMv8-ISA) and adressing more than 4 GB RAM. According to ARM the performance per MHz is a lot better and even surpasses a Cortex-A9 core.

The integrated Adreno 308 ist the integrated graphics card that supports OpenGL ES 3.0.

The integrated wireless radios support WiFi 802.11ac Wave 2, Bluetooth 4.1, GPS/GLONASS/Baidou, 2G, 3G and 4G (LTE Cat.4) standards. Futhermore, the SoC is able to decode 1080p videos in H.265 (encode only in H.264) and cameras with up to 13 MP.

The power consumption of the chip is ranging in the lower range, and therefore it is also suited for smaller smartphones. It is manufactured in 28 nm LP at TSMC.
