Apple S5 vs MediaTek Helio X27 MT6797X vs UNISOC Tiger T310

Apple S5

The Apple S5 is a 64-Bit dual core processor for the Apple Watch Series 5 (40 and 44mm). It integrates a GPU, 32 GB flash memory, Bluetooth 5.0, 1 GB RAM, 802.11 b/g/n 2.4 GHz WiFi and satellite positioning (GPS, GLONASS, Galileo, QZSS).

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.

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).
