Qualcomm Snapdragon 400 8930AB vs Rockchip RK3188 vs Qualcomm Snapdragon S4 Plus APQ8060A

Qualcomm Snapdragon 400 8930AB

The Qualcomm Snapdragon 400 8930AB is a high clocked dual-core ARM based SoC for smartphones. It integrates two Krait 300 CPU cores clocked at max. 1.7 GHz (the MSM8930 offers only Krait 200 cores at 1.2 GHz) and an Adreno 305 GPU. The whole chip is produced in 28nm LP at TSMC.

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.

Qualcomm Snapdragon S4 Plus APQ8060A

The Qualcomm APQ8060A (Snapdragon S4 series) is a ARM based high-end smartphone SoC in 2012. It contains two Krait (ARMv7) CPU cores, a Adreno 225 GPU (400 MHz), a LPDDR2 memory controller (up to 500 MHz). Compared to the MSM8260A it does not feature radio elements like GSM, GPRS, UMTS or LTE (only WLAN and BT). The chip is produced in 28nm LP (low power process) at TSMC.

The Krait cores offer a slightly better performance as the standard Cortex-A9 cores and are compatible to the NEON SIMD extensions.
