Rockchip RK3288 vs HiSilicon Kirin 620 vs JLQ JR510

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.

HiSilicon Kirin 620

The HiSilicon Kirin 620 is an ARM-based octa core SoC for mid-range smartphones. It was announced at the end of 2014 and features eight ARM Cortex-A53 cores at 1.2 GHz (max.). Furthermore, the processor integrates a ARM Mali-450 MP4 graphics card, an LPDDR3 memory controller, an LTE Cat.4 modem, 802.11n WiFi and Bluetooth 4.0. The chip is manufactured in 28nm and relatively power efficient.

JLQ JR510

The JLQ JR510 is a lower mainstream SoC for (Android-based) smartphones and tablets by JLQ, a joint venture with Qualcomm and several Chinese companies.

The JLQ JR510 integrates eight ARM Cortex-A55 cores (similar to the Snapdragon 439) in two Clusters. 4 higher-clocked cores with up to 2 GHz and four power saving cores with up to 1.5 GHz.

The integrated graphics card is not an Adreno, but a ARM Mali G52MP1 (single cluster). Displays can be with resolutions up to 1080p/60Hz, for 720p 90 Hz is possible.

The JR510 also includes an AI accelerator with a theoretical performance of up to 1.23 TOPS. For connectivity, the SoC supports 4G (Cat4 / 7), Wi-Fi 5 (802.11ac), Bluetooth 5.0, FM and GNSS.
