Qualcomm Snapdragon 400 8930AB vs Rockchip RK3288

Qualcomm Snapdragon 400 8930AB

The Qualcomm Snapdragon 400 8930AB is a high clocked dual-core ARM based SoC for smartphones. It integrates two Krait 300 CPU cores clocked at max. 1.7 GHz (the MSM8930 offers only Krait 200 cores at 1.2 GHz) and an Adreno 305 GPU. The whole chip is produced in 28nm LP at TSMC.

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.
