Rockchip RK3288 vs Marvell Armada PXA1908 vs HiSilicon Kirin 930

Rockchip RK3288

The Rockchip RK3288 is a mid-range ARM SoC for Android and Chrome OS mobile systems. It integrates four Cortex-A12 cores clocked at up to 1.8 GHz. ARM calls these cores Cortex-A17 due to them having very similar performance levels. The SoC includes an ARM Mali-T760 MP4 (also called Mali-T764) GPU clocked at 600 MHz and a dual-channel DDR3, DDR3L, LPDDR2, LPDDR3 memory controller.

The ARM Cortex-A12 is the successor to the Cortex-A9 and is based on a 32 Bit ARMv7-A microarchitecture. A single A12 core should be roughly 40 % more powerful than an A9 core according to ARM.

The integrated video engine supports encoding of H.264, VP8, and MVC videos up to 1080p. Decoding is supported for videos up to 4K H.264 and 10 Bit H.265.

The chip is manufactured under a 28 nm HKMG process.

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. 

HiSilicon Kirin 930

The HiSilicon Kirin 930 is an ARM-based octa-core SoC (system-on-a-chip) for smartphones and tablets. It was launched in the first half of 2015. It integrates two quad-core clusters of Cortex-A53 cores (big.LITTLE). The performance cluster clocks at up to 2 GHz, the power saving cluster at up to 1.5 GHz. Furthermore, the SoC integrates a ARM Mali-T628 MP4 graphics card and LTE Cat. 6 modem. The SoC is manufactured in 28nm and thanks to the small Cortex-A53 cores also suited for smaller smartphones.
