Rockchip RK3188 vs MediaTek MT8161 vs NXP i.MX 6SLL

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.

MediaTek MT8161

The MediaTek MT8161 is an ARM based entry-level to mid-range SoC for (Android based) tablets. It offers four ARM Cortex-A53 processor cores (quad-core) that are clocked with up to 1.3 GHz. Furthermore, an ARM Mali-720 graphics card, a LPDDR3 memory controller (e.g., accessing 1 GB in the Lenovo Tab 2 A8-50), Bluetooth 4.0 and dual-band 802.11 b/g/n are integrated in the SoC.

The performance is situated in the entry level of 2015 and often similar to the Kirin 910T (see benchmark below).

NXP i.MX 6SLL

The NXP i.MX 6SLL or i.MX6SLL (i.MX 6 Series, MCIMX6V7DVN10AB Part Number) is a single core processor for e-readers. It integrates a single ARM Cortex-A9 processor core clocked at up to 1 GHz and a 2D graphics accelerator called Pixel Processor PXP (including E-INK display controller EPDC with support of up to 2332x1650 and 5-bit greyscale). The integrated memory controller supports up to 400 MHz LPDDR2 or LPDDR3 (32-bit interface). Flash memory can be attached using eMMC 5.0 or SD 3.0 (three connections available). Furthermore, the SoC supports 2x USB 2.0 OTH with PHY. The chip is pin-compatible with the i.MX 6SoloLite which features an additional Vivante GC320 graphics card. WiFi, Bluetooth, GPS or other peripherals have to be connected with external chips.
