Rockchip RK3066 1.5 GHz vs ARM Cortex A8 1.2 GHz vs UNISOC Tiger T310

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

ARM Cortex A8 1.2 GHz

UNISOC Tiger T310

The Unisoc Tiger T310 is a SoC for smartphones and tablets of the entry level. It was first announced in mid 2019 and integrates four CPU cores (quad core). One big Cortex-A75 core clocked at up to 2 GHz and three small A55 cores with up to 1.8 GHz.

Furthermore, the chip integrates an LTE modem (Cat 7, TDD-LTE, FDD-LTE, TDSCDMA, WCDMA, CDMA, GSM), Bluetooth 5.0 and WiFi b/g/n/ac. The integrated ISP supports up to two cameras (16 MPixel and 8 Mpixel, maximum 30 fps video capture) and the GNSS can use all current standards (GPS, Glonass, Beidou, Galileo).

The memory controller is able to drive LPDDR3 at 933 MHz and faster LPDDR4x at 1333 MHz.

The PowerVR GE8300 iGPU is from Imagination and clocked at up to 800 MHz.

The chip is produced in 12nm at TSMC and should offer a rather good power efficiency (for 2019).
