MediaTek Helio X27 MT6797X vs Marvell Armada PXA1908 vs HiSilicon Kirin 930

MediaTek Helio X27 MT6797X

The Mediatek Helio X27 MT6797X is an upper mainstream ARM SoC for smartphones (mainly Android based). It is manufactured in a 20 nm process and is equipped with 10 CPU cores. Two fast Cortex-A72 cores are running at up to 2.6 GHz (performance), four Cortex-A53 cores at up to 2 GHz (balanced) and four Cortex-A53 cores at up to 1.6 GHz (efficiency). All cores support 64-bit and the utilization of three clusters is supposed to improve efficiency according to Mediatek. The two A72 cores are only designed for short "Burst-Performance scenarios" according to Mediatek and are probably not used for sustained workloads. Compared to the similar named MT6797, the MT6797X was introduced later and offers higher clock speeds for CPU and GPU.

The integrated ARM Mali T880 MP4 (according to Wikipedia) GPU is clocked at up to 875 MHz and has four cluster (from 16) from the Midgard (4th Gen) architecture.

The chip also includes an LTE modem (Cat. 6 300/50 Mbps, DC-HSPA+, TD-SCDMA, EDGE, CDMA2000, ...) as well as a WLAN 802.11ac (280 Mbps) modem. GPS/Glonass/BeiDou is supported for location. The integrated video encoder can handle up to 4Kx2K H.265 at 30 fps and HDR. The SoC can also decode H.265, H.264 and VP9 in 4K30. 

Power Consumption

The processor is manufactured in a 20 nm process at TSMC and should have an average power consumption under load.

Marvell Armada PXA1908

The Marvell Armada PXA1908 is an ARM based low end SoC for smartphones and tablets. The chip was announced in late 2014 and integrates four 64-Bit Cortex-A53 processor cores with up to 1.2 GHz. As a graphics card, the SoC integrates a Vivante GC7000UL. Furthermore, a LPDDR2/3 memory controller and a HSPA+/WCDMA/LTE Cat. 4 (max. 150 Mbit/s) radio is integrated. The SoC is manufactured in 28nm and also suited for small smartphones. 

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.
