Qualcomm Snapdragon W5 Gen 1 vs MediaTek MT8163 V/B 1.3 GHz vs HiSilicon Kirin 655

Qualcomm Snapdragon W5 Gen 1

The Qualcomm Snapdragon W5 Gen 1 is a SoC for smartwatches and fitness trackers in the Wear series. It integrates a CPU with four ARM Cortex A53 cores and up to 1.7 GHz, an Adreno 702 GPU with up to 1GHz, a single channel (1x16) LPDDR4 2133 MHz memory controller, Bluetooth 5.3, WLAN 802.11n (2.4 and 5 GHz) and an LTE modem (Rel 13 with Cat1 bis support). The SoC (SW5100) is manufactured using a modern 4nm process. In contrast to the W5 Plus, the W5 does not integrate an additional Always-On-Chip (QCC5100 with a 250 MHz Cortex-M55 CPU).

MediaTek MT8163 V/B 1.3 GHz

The MediaTek MT8163 V/B is an ARM based entry-level to mid-range SoC for (Android based) tablets. It offers four ARM Cortex-A53 processor cores (quad-core) that are clocked with up to 1.3 GHz. Furthermore, an ARM Mali-T720 MP2 graphics card clocked at 520 MHz, a DDR3x32 1600Mbps memory controller, Bluetooth 4.0, 802.11 b/g/n, GPS and FM are integrated in the SoC.

The similar named MediaTek MT8163 V/A is the faster version, with a CPU clock o up to 1.5 GHz and GPU of up to 600 MHz.

The performance is situated in the entry level of 2015 and often similar to the Kirin 910T (see benchmark below).

HiSilicon Kirin 655

The 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.
