Rockchip RK3168 vs Broadcom BCM21664T vs NXP i.MX 6SLL

Rockchip RK3168

The Rockchip RK3168 is a low-end ARM SoC designed primarily for smartphones. It integrates two Cortex-A9 CPU cores with NEON extension, a PowerVR SGX 540 graphics card (400 MHz) and a memory controller for low-power (LP-) DDR2/DDR3. The performance should be comparable to other similarly clocked Cortex-A9 SoCs such as the Samsung Exynos 4210. Thanks to its 28nm manufacturing, the RK3168 is relatively power efficient and should enable longer battery life.

Broadcom BCM21664T

► remove from comparison

The Broadcom BCM21664T is an ARM based entry-level SoC for smartphones that integrates two Cortex-A9 CPU cores clocked at up to 1.2 GHz and a HSPA+ modem with support for 21 Mbps HSDPA and 5.8 Mbps HSUPA. Furthermore, a VideoCore-IV GPU and a video decoder (H.264 1080p capable) and encoder (720p) are built into the SoC.

NXP i.MX 6SLL

► remove from comparison

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.
