Qualcomm Snapdragon 400 MSM8926 vs Qualcomm Snapdragon S4 Plus MSM8227 vs Qualcomm Snapdragon S4 Plus MSM8260A

Qualcomm Snapdragon 400 MSM8926

The Qualcomm Snapdragon 400 MSM8926 is an entry-level ARM-SoC for Android smartphones and tablets. It offers four Cortex-A7 cores clocked at up to 1.2 GHz (Quad-Core) as well as an Adreno 305 graphics card at 450 MHz. Furthermore, a HSPA+/LTE radio is integrated in the SoC, which is manufactured in a 28-nanometer LP process.

Qualcomm Snapdragon S4 Plus MSM8227

The Qualcomm Snapdragon S4 MSM8277 is a mid-range SoC for smartphones and tablets (mostly Android based). It contains two Krait (improved ARM Cortex-A9) CPU cores at 1.0 GHz and a Adreno 305 graphics card. A memory controller and radio elements (excluding LTE) are also included. The chip is produced in 28nm LP process at TSMC.

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.
