NXP i.MX 6SLL vs Rockchip RK3188

NXP i.MX 6SLL

► remove 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.

Rockchip RK3188

► remove

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.
