Qualcomm Snapdragon S4 Plus MSM8260A

The Qualcomm MSM8260A (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.  The chip is produced in 28nm LP (low power process) at TSMC. Compared to the MSM8960, the 8260A does not support LTE.

The Krait cores offer a slightly better performance as the standard Cortex-A9 cores and are compatible to the NEON SIMD extensions.
