Qualcomm Snapdragon S3 MSM8660 vs Qualcomm Snapdragon 400 MSM8226 vs Qualcomm Snapdragon S4 Plus MSM8260A

Qualcomm Snapdragon S3 MSM8660

The Qualcomm Snapdragon S3 MSM8660 is an entry level SoC for smartphones and tablets (mostly Android based). It contains two Scorpion cores (enhanced ARM Cortex-A8) clocked at up to 1.7 GHz, a Adreno 220 graphics card and radio elements (including CDMA2000, which is the difference to the MSM8260).

Qualcomm Snapdragon 400 MSM8226

The Qualcomm Snapdragon 400 MSM8226 is an entry-level ARM-SoC for Android smartphones. It integrates four Cortex-A7 cores at up to 1.2 GHz (Quad-Core) and a Adreno 305 graphics card at 450 MHz. Furthermore, a HSPA+ radio, WLAN (b,g,n) and Bluetooth 4.0 are integrated in the SoC.

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.
