The Samsung Exynos 4 Quad (also called Exynos 4412, introduced in 2012) is an ARM SoC for tablets and smartphones. It includes a quad-core processor based on the Cortex-A9 architecture (including NEON SIMD extension), which clocks with 1.4 to 1.6 GHz (depending on the model). Thus, the computing power is similar to competitors like Nvidia's Tegra 3 SoC. The memory controller supports LPDDR2, DDR2 and DDR3 with a maximum of two 32-bit channels and 400 MHz clock speed, resulting in a bandwidth of up to 6.4 GB/s.
The SoC integrates an ARM Mali-400 MP4 GPU (15.8 GFLOPS at 440 MHz). Typical smartphone games (2012) will run fluently even in high resolutions like 1280 x 720 pixels. Videos can be accelerated by a multi-format video decoder (1080p AVI, WMV, H.264, H.263, VC1, MPEG2, MPEG4).
The chip is produced in Samsung fabs in 32nm HKMG and mainly found in high-end devices like the Samsung Galaxy S3 or Note 2. Depending on the clock speed, the power consumption should be between 2 and 4 W (estimated).
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.
The Qualcomm MSM8230 (Snapdragon S4 Plus series) is a 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 radio elements. The chip is produced in 28nm LP (low power process) at TSMC. Compared to the MSM8930, the 8230 lacks LTE.
The Krait cores offer a slightly better performance as the standard Cortex-A9 cores and are compatible to the NEON SIMD extensions.
