Qualcomm Snapdragon S4 Plus APQ8060A vs Apple A6x vs Rockchip RK3066 1.5 GHz

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.

Apple A6x

The Apple A6x is a dual-core-SoC (System on a Chip) with ARM compatible CPU cores (ARMv7s instruction set). Both can be clocked at up to 1400 MHz depending on the load. It is used in the iPad 4 and compared to the A6 in the iPhone 5, the A6x offers a faster GPU (PowerVR SGX544MP4).

The CPU-Performance of the A6x is similar to the Qualcomm Snapdragon S4 Pro MSM8960T, while the GPU is about as fast as the Adreno 320.

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.
