Rockchip RK3168 vs Renesas MP5232 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.

Renesas MP5232

The Renesas MP5232 is an entry level ARM Cortex-A9 dual-core SoC with integrated LTE cat. 4 radio. It aims at "cheap" Android based smartphones with LTE between 150 and 300 Dollars. Both CPU cores are clocked at up to 1.5 GHz, although e.g. in the Samsung Galaxy Core LTE SM-G386F they are limited to 1.2 GHz. In addition to the ARM processor cores, the MP5232 features a PowerVR SGX544 graphics card, LTE cat. 4 / DC-HSPA+ 3G / Edge radio, 1080p video de- and encoder, and a 20 MP ISP.
