Rockchip RK3188 vs HiSilicon k3v2 Hi3620 vs Rockchip RK3066 1.5 GHz

Rockchip RK3188

The Rockchip RK3188 is a fast ARM SoC primarily designed for tablets. It integrates four ARM Cortex A9 cores with NEON extension and a clock speed of up to 1.8 GHz, a Mali-400 MP4 graphics card (up to 600 MHz, 24 GFLOPS) and a low-power (LP-)DDR2/DDR3 memory controller. Due to the high clock rates, the performance of the CPU and GPU is superior to other Cortex-A9 quad-cores such as the Nvidia Tegra 3 and Samsung Exynos 4412. These high frequencies are possible due to the 28nm process (TSMC). However, this results in high power consumption and is thus not suited for compact smartphones.

Rockchip RK3066 1.5 GHz

The Rockchip RK3066 is a cheap ARM based SoC for Tablets and Smartphones. It integrates two ARM Cortex-A9 (ARMv7) CPU cores with NEON extensions, a ARM Mali-400MP4 (quad-core clocked at 250 MHz) graphics card and a video de- and encoder as main components. The integrated memory controller supports a maximum of 2 GB DDR1, DDR2 or DDR3 memory.

The CPU cores can be clocked up to 1.6 GHz depending on the cooling solution of the tablet / smartphone.
