The Mediatek MT8176 is an upper mainstream ARM SoC (System on a chip) that was introduced in October 2016 and is primarily used for Android based tablets. It has two fast Cortex-A72 CPU cores running at up to 2.1 GHz and four Cortex-A53 cores for power-saving in a big.LITTLE configuration. The graphics unit is based on the IMG Series 6XT (Rogue) and has the designation PowerVR GX6250 clocked at 600 MHz. Among others, the GPU includes a video decoder with 4K and H.265 support (not verified, but was already the case for the older MT8173).
Processor
The biggest highlight of the SoC are the new Cortex-A72 cores, which can be seen as the successors to the Cortex-A57 design. ARM promises much more performance in combination with reduced power consumption, which results in an excellent per-thread performance with the very high maximum clock of 2.4 GHz. The architecture is based on ARMv8-ISA and therefore supports 64-bit.
The four slower, but therefore very frugal Cortex-A53 cores (clocks unknown, probably around 1.4 GHz) are supposed to reduce the power consumption and are always active with light workloads. The big.LITTLE configuration also allows the simultaneous use of all six cores (or any combination of cores from both clusters), so the MT8173 can be called a real hexa-core.
Graphics
The graphics unit is based on Series 6XT (Rogue) from IMG and has the designation PowerVR GX6250. The 2-cluster chip has a unified-shader architecture with a total of 64 FP32 ALUs as well as 4 TMUs. Compared to the MT8173, the clocks were reduced from 700 to 600 MHz, so the gaming performance is a bit lower. High-resolution screens and complex Android games should be powered without bigger problems.
The Qualcomm Snapdragon 450 (SD450) is a lower mainstream SoC for (Android based) smartphones and tablets. It features eight ARM Cortex-A53 cores at up to 1.8 GHz and is already manufactured in the power efficient 14nm process. The integrated X9 LTE modem supports Cat. 7 with maximum transfer rates of 300 Mbps (downstream) and 150 Mbps (upstream). The SoC also includes an Adreno 506 GPU with support for Vulkan and OpenGL ES 3.1. WiFi 802.11ac (1x1, max 364 Mbps) and Bluetooth 4.1 are supported as well. The memory controller supports LPDDR3 (single channel) and the integrated video engine supports H.264 (encode and decode) and HEVC (only decode) in 1080p.
