Mediatek MT8121

The Mediatek MT8121 is a low-cost ARM SoC (System on a Chip) mainly used in tablets. It is manufactured in 28 nm and integrates a quad-core Cortex-A7 processor and a PowerVR SGX 544 GPU. The CPU cores are typically clocked at 1.3 GHz while the GPU is clocked at 156 MHz.
Performance
Since the Cortex-A7 architecture is somewhat slower than a Krait or Cortex-A9 design at the same clock speeds, the performance of the MT8121 is just below Nvidia's Tegra 3 or the Samsung Exynos 4412. The PowerVR SGX 544 is also just a low-cost solution not designed for ultra-high resolution displays or very demanding games.
Features
In addition to the processor and GPU, the SoC integrates a decoder for 1080p video, WiFi, Bluetooth 4.0 as well as GPS, but lacks a 2G/3G/4G radio. Cameras are supported up to a resolution of 13 MP.
Power consumption
Thanks to the energy-efficient A7 cores and 28 nm manufacturing, the power consumption is likely very low and suitable for even smaller tablets.
