Rockchip RK3066 1.5 GHz vs HiSilicon Kirin 910T vs Marvell PXA986

Rockchip RK3066 1.5 GHz

The Rockchip RK3066 is a cheap ARM based SoC for Tablets and Smartphones. It integrates two ARM Cortex-A9 (ARMv7) CPU cores with NEON extensions, a ARM Mali-400MP4 (quad-core clocked at 250 MHz) graphics card and a video de- and encoder as main components. The integrated memory controller supports a maximum of 2 GB DDR1, DDR2 or DDR3 memory.

The CPU cores can be clocked up to 1.6 GHz depending on the cooling solution of the tablet / smartphone.

Additional Features according to Wikipedia

• VPU (Video Processing Unit) Multi-Media Processor supporting 1080p image and video decoding
• HDMI 1.4 Interface
• 2-channels TFT LCD Interface with 5 layers and 3D Display (1920×1080 Maximum Display Size)
• USB 2.0 Interface
• SD/MMC Interface

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.

Marvell PXA986

The Marvell PXA986 is an ARM based dual-core SoC for smartphones and tablets (mostly Android based). It contains two Cortex-A9 CPU cores usually clocked around 1.2 GHz and a Vivante GC1000 graphics card. The integrated video processor is able to handle 720p30 content in H.263, H.264 BP and MPEG4 SP encoding. Furthermore, a GSM/EDGE/WCDMA/HSDPA radio is included in the chip.
