The Qualcomm Snapdragon 400 APQ8026 is an entry-level ARM-SoC for Android smartphones and smartwatches. It integrates four Cortex-A7 cores at up to 1.2 GHz (Quad-Core) and a Adreno 305 graphics card at 450 MHz. Furthermore, Bluetooth 4.0 is integrated in the SoC.
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.

The Qualcomm MSM8960T (Snapdragon S4 Pro) is a fast ARM SoC, which is mainly used in smartphones. It integrates a Krait-based dual-core processor and an Adreno 320 graphics card. Furthermore it features an integrated LPDDR2 memory controller (dual channel, max. 500 MHz) as well as various radio standards including LTE. The chip is fabricated at TSMC in a 28nm LP process.
Unlike older Qualcomm SoCs, which are still based on slower Scorpion cores, the MSM8960T uses the modern Krait architecture. The Krait design is significantly faster than the Cortex-A5, Cortex-A7 and Cortex-A9 architecture from ARM and just behind the high-end Cortex-A15. The two cores are clocked at 1.7 GHz and offer a performance, which is even above some older quad-cores like Nvidia's Tegra 3 or the Samsung Exynos 4412.
The Adreno 320 graphics card is the same as found in the Snapdragon 600 and one of the fastest mobile GPUs in mid-2013. The GPU is clocked at 400 MHz and offers enough performance for demanding games and high resolution screens.
Since the MSM8960T only has two CPU cores, the power consumption should be somewhat below quad-cores like the Snapdragon 600. The chip can therefore be used in compact smartphones with a smaller battery.
