Qualcomm Snapdragon S3 MSM8660 vs Qualcomm Snapdragon S4 Plus MSM8930 vs Qualcomm Snapdragon 400 APQ8028

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 S4 Plus MSM8930

The Qualcomm MSM8930 (Snapdragon S4 Plus series) is an ARM based high-end smartphone SoC in 2012. It contains two Krait (ARMv7) CPU cores at up to 1.2 GHz, a Adreno 305 GPU, a single channel LPDDR2 memory controller and LTE radio elements.  The chip is produced in 28nm LP (low power process) at TSMC. Compared to the MSM8960, the 8930 is lower clocked, offers only a single channel memory controller, but has a faster GPU.

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

Qualcomm Snapdragon 400 APQ8028

The Qualcomm Snapdragon 400 APQ8028 is an entry-level ARM-SoC for Android smartphones and tablets. It offers four Cortex-A7 cores clocked at up to 1.6 GHz (Quad-Core) as well as an Adreno 305 graphics card at 450 MHz. The chip is manufactured in 28 nm LP at TSMC.
