Apple S5 vs HiSilicon Kirin 650

Apple S5

The Apple S5 is a 64-Bit dual core processor for the Apple Watch Series 5 (40 and 44mm). It integrates a GPU, 32 GB flash memory, Bluetooth 5.0, 1 GB RAM, 802.11 b/g/n 2.4 GHz WiFi and satellite positioning (GPS, GLONASS, Galileo, QZSS).

HiSilicon Kirin 650

The HiSilicon Kirin 650 is an ARM-based octa-core SoC for mid-range smartphones and tablets. It was announced early 2016 and features eight ARM Cortex-A53 cores. Four cores can be clocked with up to 1.7 GHz (power saving cores) and four with up to 2 GHz (performance cores). Furthermore, a ARM Mali-T830 MP2 graphics card (at 600 MHz with 40.8 GFLOPS), a 64-Bit LPDDR3 memory controller and a dual-sim capable LTE Cat. 6 (max. 300 MBit/s and GSM, WCDMA, UMTS, HSPA+) radio are integrated in the SoC.

The processor performance can be compared with the older Kirin 930 and therefore sufficient for daily usage as browsing and non demanding apps. High-end SoCs with Cortex-A57 or A72 cores however should be noticeably faster.

The SoC is produced in a modern 16nm FinFET process and is therefore very power efficient.
