Rockchip RK3288 vs Rockchip RK3188 vs HiSilicon Kirin 910T

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.

Rockchip RK3188

The Rockchip RK3188 is a fast ARM SoC primarily designed for tablets. It integrates four ARM Cortex A9 cores with NEON extension and a clock speed of up to 1.8 GHz, a Mali-400 MP4 graphics card (up to 600 MHz, 24 GFLOPS) and a low-power (LP-)DDR2/DDR3 memory controller. Due to the high clock rates, the performance of the CPU and GPU is superior to other Cortex-A9 quad-cores such as the Nvidia Tegra 3 and Samsung Exynos 4412. These high frequencies are possible due to the 28nm process (TSMC). However, this results in high power consumption and is thus not suited for compact smartphones.

HiSilicon Kirin 910T

The HiSilicon Kirin 910T is an ARM based quad core SoC for Android smartphones and tablets. As HiSilicon is fully owned by Huawei, the chip is mostly used in Huawei models like the MediaPad X1, P6 S, MediaPad M1 and Honor 3C 4G). The SoC integrates four Cortex-A9 cores (at 1.8 GHz max.), a ARM Mali-450 MP4 GPU (at 533 MHz), a 32-bit single-channel LPDDR3-1600 memory controller (533 MHz) and a LTE Cat. 4 radio. The similar named HiSilicon Kirin 910 is a 200 MHz slower clocked (CPU) version.

At the time of announcement in mid 2014, the CPU performance of the Kirin910T is in the mid-range of smartphone and tablet SoCs. The power consumption is a bit higher than usual, as the CPU cores are rather high clocked.
