Mediatek MT6582

The Mediatek MT6582 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 as well as an ARM Mali-400 MP2 GPU clocked at 500 MHz (according to Wikipedia the main difference to the MT6582M that is clocked at 416 MHz). Furthermore, the chip supports dual SIM, UMTS and HSPA+, WiFi, FM, Bluetooth and GPS. 

The CPU performance of the MT6582 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.
