The Amlogic AML8726-M is a cheap SoC (System on a Chip) for Android tablets and smartphones. It integrates two ARM Cortex-A9 cores (max. 1,5 GHz) with SIMD extensions and an ARM Mali-400 graphics card. Furthermore, the chip supports hardware decoding of 1080p videos according to Amlogic.
The HiSilicon Kirin 659 is an ARM-based octa-core SoC for mid-range smartphones and tablets. It was announced mid 2017 and features eight ARM Cortex-A53 cores. Four cores can be clocked with up to 1.7 GHz (power saving cores) and four with up to 2.36 GHz (performance cores). The difference to the older Kirin 650 and Kirin 655 SoCs is the higher clock speed of the performance cores (2.35 versus 2.1 and 2.0 GHz). The slightly older Kirin 658 is very similar. The 659 is in our benchmarks around 4% faster than the 658 and offers a better LTE radio (Cat. 13).
Furthermore, a ARM Mali-T830 MP2 graphics card (at >=900 MHz), a 64-Bit LPDDR3 memory controller and a dual-sim capable LTE Cat. 6 (max. 300 MBit/s and GSM, WCDMA, UMTS, HSPA+) radio are integrated in the SoC. The processor performance can be compared with the older Kirin 930 and therefore sufficient for daily usage as browsing and non demanding apps. High-end SoCs with Cortex-A57 or A72 cores however should be noticeably faster. The SoC is produced in a modern 16nm FinFET process and is therefore very power efficient.
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.
