Rockchip RK3288 vs Apple A6x vs Rockchip RK2918 1.2 GHz
Rockchip RK3288► remove
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.
Apple A6x► remove
The Apple A6x is a dual-core-SoC (System on a Chip) with ARM compatible CPU cores (ARMv7s instruction set). Both can be clocked at up to 1400 MHz depending on the load. It is used in the iPad 4 and compared to the A6 in the iPhone 5, the A6x offers a faster GPU (PowerVR SGX544MP4).
