Rockchip RK3168 vs Marvell Armada PXA1908 vs CSR8670

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.

Marvell Armada PXA1908

The Marvell Armada PXA1908 is an ARM based low end SoC for smartphones and tablets. The chip was announced in late 2014 and integrates four 64-Bit Cortex-A53 processor cores with up to 1.2 GHz. As a graphics card, the SoC integrates a Vivante GC7000UL. Furthermore, a LPDDR2/3 memory controller and a HSPA+/WCDMA/LTE Cat. 4 (max. 150 Mbit/s) radio is integrated. The SoC is manufactured in 28nm and also suited for small smartphones.
