Qualcomm Snapdragon S4 Plus MSM8960 vs Rockchip RK3066 1.5 GHz vs Qualcomm Snapdragon 400 MSM8926

Qualcomm Snapdragon S4 Plus MSM8960

The Qualcomm MSM8960 (Snapdragon S4 series) is a ARM based high-end smartphone SoC in 2012. It contains two Krait (ARMv7) CPU cores at 1.5 - 1.7 GHz, a Adreno 225 GPU (400 MHz), a LPDDR2 memory controller (up to 500 MHz) and radio elements including LTE. 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.

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.
