Apple S6 vs HiSilicon Kirin 655 vs Apple S9 SiP
Apple S6
► remove from comparisonThe Apple S6 is a 64-Bit dual core processor for the Apple Watch Series 6 (40 and 44mm). It integrates a GPU, 32 GB flash memory, Bluetooth 5.0, 1 GB RAM, 802.11 b/g/n 2.4 and 5 GHz WiFi and satellite positioning (GPS, GLONASS, Galileo, QZSS). According to Apple the SiP has two CPU cores based on the Apple A13 and offers 20% more performance than the old Apple S5 in the Watch Series 5.
HiSilicon Kirin 655
► remove from comparisonThe HiSilicon Kirin 655 is an ARM-based octa-core SoC for mid-range smartphones and tablets. It was announced late 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 2.1 GHz (performance cores). The difference to the older Kirin 650 is the 100 MHz higher clock speed of the performance cores.
Furthermore, a ARM Mali-T830 MP2 graphics card (at 600 MHz or 900 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.
Apple S9 SiP
► remove from comparisonThe Apple S9 SiP (System in a Package) is a 64-bit processor with two cores (Sawtooth Dual-Core) that is used in the Apple Watch Series 9. The two CPU cores are based on the same microarchitecture as in the Apple A15 SoC. The chip also includes a Neural Engine (with 4 cores) for AI tasks for the first time.
The S9 offers 64 GB internal memory, L1 GPS, GNSS, Galileo and BaeiDou, WLAN 4 (802.11n), Bluetooth 5.3), and LTE / UMTS (optional). The ultra-wideband chip Apple U1 is also integrated.
The chip is manufactured in the modern 4nm process at TSMC (N4P).
