Qualcomm Snapdragon S4 Plus MSM8930 vs Rockchip RK3066 1.5 GHz vs Qualcomm Snapdragon 400 APQ8026

Qualcomm Snapdragon S4 Plus MSM8930

The Qualcomm MSM8930 (Snapdragon S4 Plus series) is an ARM based high-end smartphone SoC in 2012. It contains two Krait (ARMv7) CPU cores at up to 1.2 GHz, a Adreno 305 GPU, a single channel LPDDR2 memory controller and LTE radio elements.  The chip is produced in 28nm LP (low power process) at TSMC. Compared to the MSM8960, the 8930 is lower clocked, offers only a single channel memory controller, but has a faster GPU.

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

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.
