Qualcomm Snapdragon 400 MSM8928 vs Rockchip RK3288 vs Qualcomm Snapdragon 400 APQ8026

Qualcomm Snapdragon 400 MSM8928

The Qualcomm Snapdragon 400 MSM8928 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. Furthermore, a HSPA+/LTE radio is integrated in the SoC, which is manufactured in a 28-nanometer LP process.

Rockchip RK3288

The Rockchip RK3288 is a mid-range ARM SoC for Android and Chrome OS mobile systems. It integrates four Cortex-A12 cores clocked at up to 1.8 GHz. ARM calls these cores Cortex-A17 due to them having very similar performance levels. The SoC includes an ARM Mali-T760 MP4 (also called Mali-T764) GPU clocked at 600 MHz and a dual-channel DDR3, DDR3L, LPDDR2, LPDDR3 memory controller.

The ARM Cortex-A12 is the successor to the Cortex-A9 and is based on a 32 Bit ARMv7-A microarchitecture. A single A12 core should be roughly 40 % more powerful than an A9 core according to ARM.

The integrated video engine supports encoding of H.264, VP8, and MVC videos up to 1080p. Decoding is supported for videos up to 4K H.264 and 10 Bit H.265.

The chip is manufactured under a 28 nm HKMG process.

Qualcomm Snapdragon 400 APQ8026

The Qualcomm Snapdragon 400 APQ8026 is an entry-level ARM-SoC for Android smartphones and smartwatches. It integrates four Cortex-A7 cores at up to 1.2 GHz (Quad-Core) and a Adreno 305 graphics card at 450 MHz. Furthermore, Bluetooth 4.0 is integrated in the SoC.
