HiSilicon Kirin 658 vs Mediatek MT8766B vs HiSilicon Kirin 930

HiSilicon Kirin 658

The HiSilicon Kirin 658 is an ARM-based octa-core SoC for mid-range smartphones and tablets. It was announced early 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 2.35 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).

Furthermore, a ARM Mali-T830 MP2 graphics card (at 900 MHz with 40.8 GFLOPS), 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.

Mediatek MT8766B

The Mediatek MT8766B is an entry-level ARM SoC for smartphones and tablets (mainly Android-based) that was introduced in 2020. It integrates four ARM Cortex-A53 cores clocked at up to 2 GHz. and a PowerVR GE6300 GPU. It looks very similar to the older Helio A20 (-200 MHz CPU core clock).

The integrated memory controller supports LPDDR4x. Furthermore, a LTE radio with Cat-4 DL (150 Mbps download) and Cat-5 UL (75 Mbps upload) and a 802.11 a/b/g/n/ac Wi-Fi 5 modem is integrated.

The SoC should be produced in the same 12nm process as the Helio A20 (most likely the same chip).

HiSilicon Kirin 930

The HiSilicon Kirin 930 is an ARM-based octa-core SoC (system-on-a-chip) for smartphones and tablets. It was launched in the first half of 2015. It integrates two quad-core clusters of Cortex-A53 cores (big.LITTLE). The performance cluster clocks at up to 2 GHz, the power saving cluster at up to 1.5 GHz. Furthermore, the SoC integrates a ARM Mali-T628 MP4 graphics card and LTE Cat. 6 modem. The SoC is manufactured in 28nm and thanks to the small Cortex-A53 cores also suited for smaller smartphones.
