NXP i.MX 6SLL vs HiSilicon Kirin 910 vs Broadcom BCM21664T

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.

HiSilicon Kirin 910

The HiSilicon Kirin 910 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 1.6 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 910T is a 200 MHz higher clocked (CPU) version.

At the time of announcement in mid 2014, the CPU performance 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.

Broadcom BCM21664T

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.
