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.
The Mediatek MT6580M is a system-on-a-chip (SoC) for low-cost tablets and smartphones. It is manufactured in 28 nm and offers a quad-core Cortex-A7 processor (max 1.3 GHz) as well as an ARM Mali-400 MP2 GPU (MP2 unconfirmed, but the similar MT6582 has a MP2 clocked at 416 MHz). Furthermore, the chip supports dual SIM, UMTS and HSPA+, WiFi, FM, Bluetooth and GPS.
The CPU performance of the MT6580M is similar to other Cortex-A7 SoCs clocked at the same frequency. Depending on the benchmark, the CPU power is roughly comparable with the Nvidia Tegra 3 and sufficient for everyday applications such as browsing. The GPU will handle only simple Android games in moderate resolutions.
The dual-core Mediatek MT6572 is an entry-level ARM SoC found in a number of Android smartphones and tablets. It contains two Cortex-A7 CPU cores and an ARM Mali-400 graphics card. The CPU cores are typically clocked at 1.2 GHz and the GPU core at 500 MHz. Furthermore, an LPDDR2 memory controller, a 2G/3G (HSPA+) radio, 720p video decoder, WLAN, Bluetooth and GPS modules are integrated onto the chip.
Performance
As the Cortex A7 architecture is slightly slower per clock than the older Cortex-A9 or Krait cores, the CPU performance is approximately on the same level as a Samsung Exynos 4210 or similar. The ARM Mali-400 GPU is only an entry-level graphics card unsuited for demanding Android 3D games.
Power Consumption
Due to the power-efficient Cortex-A7 cores and the 28 nm manufacturing process, the power consumption of the Mediatek MT6572 is low enough to be used in smaller smartphones.
