Qualcomm Snapdragon S4 Plus MSM8960 vs Rockchip RK3066 1.5 GHz vs Apple A6x

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.

Additional Features according to Wikipedia

• VPU (Video Processing Unit) Multi-Media Processor supporting 1080p image and video decoding
• HDMI 1.4 Interface
• 2-channels TFT LCD Interface with 5 layers and 3D Display (1920×1080 Maximum Display Size)
• USB 2.0 Interface
• SD/MMC Interface

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.
