Rockchip RK3288 vs unknown vs UNISOC Tiger T310

Rockchip RK3288

The Rockchip RK3288 is a mid-range ARM SoC for Android and Chrome OS mobile systems. It integrates four Cortex-A12 cores clocked at up to 1.8 GHz. ARM calls these cores Cortex-A17 due to them having very similar performance levels. The SoC includes an ARM Mali-T760 MP4 (also called Mali-T764) GPU clocked at 600 MHz and a dual-channel DDR3, DDR3L, LPDDR2, LPDDR3 memory controller.

The ARM Cortex-A12 is the successor to the Cortex-A9 and is based on a 32 Bit ARMv7-A microarchitecture. A single A12 core should be roughly 40 % more powerful than an A9 core according to ARM.

The integrated video engine supports encoding of H.264, VP8, and MVC videos up to 1080p. Decoding is supported for videos up to 4K H.264 and 10 Bit H.265.

The chip is manufactured under a 28 nm HKMG process.

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).
