Rockchip RK3168 vs HiSilicon Kirin 620 vs ARM Cortex-M4

Rockchip RK3168

The Rockchip RK3168 is a low-end ARM SoC designed primarily for smartphones. It integrates two Cortex-A9 CPU cores with NEON extension, a PowerVR SGX 540 graphics card (400 MHz) and a memory controller for low-power (LP-) DDR2/DDR3. The performance should be comparable to other similarly clocked Cortex-A9 SoCs such as the Samsung Exynos 4210. Thanks to its 28nm manufacturing, the RK3168 is relatively power efficient and should enable longer battery life.

HiSilicon Kirin 620

The HiSilicon Kirin 620 is an ARM-based octa core SoC for mid-range smartphones. It was announced at the end of 2014 and features eight ARM Cortex-A53 cores at 1.2 GHz (max.). Furthermore, the processor integrates a ARM Mali-450 MP4 graphics card, an LPDDR3 memory controller, an LTE Cat.4 modem, 802.11n WiFi and Bluetooth 4.0. The chip is manufactured in 28nm and relatively power efficient.
