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.
The Rockchip RK3288 is a mid-range ARM SoC for Android and Chrome OS mobile systems. It integrates four Cortex-A12 cores clocked at up to 1.8 GHz. ARM calls these cores Cortex-A17 due to them having very similar performance levels. The SoC includes an ARM Mali-T760 MP4 (also called Mali-T764) GPU clocked at 600 MHz and a dual-channel DDR3, DDR3L, LPDDR2, LPDDR3 memory controller.
The ARM Cortex-A12 is the successor to the Cortex-A9 and is based on a 32 Bit ARMv7-A microarchitecture. A single A12 core should be roughly 40 % more powerful than an A9 core according to ARM.
The integrated video engine supports encoding of H.264, VP8, and MVC videos up to 1080p. Decoding is supported for videos up to 4K H.264 and 10 Bit H.265.
The chip is manufactured under a 28 nm HKMG process.
