Mediatek MT8127 vs Mediatek MT6592 vs MediaTek MT6572

Mediatek MT8127

The MediaTek MT8127 is a cheap ARM-SoC (System on a Chip) that is mainly used in Android based tablets. It is manufactured in 28 nm and integrates a quad-core ARM Cortex-A7 processor clocked at 1.5 GHz (typically), a ARM Mali-450 MP4 graphics card (at 600 MHz) and a single channel 32 Bit DDDR3-1333 memory controller (max. 5.3 GB/s).

Processor

The ARM Cortex-A7 design is a 32-Bit entry level core with a much lower performance per MHz than the Cortex-A9. Therefore, the MT8127 is only positioned in the lower mid-range similar to the Qualcomm Snapdragon 400.

Features

The MT8127 integrates function blocks for full HD videos (en- and decoders), WiFi, Bluetooth 4.0, GPS and FM radio. Camera modules are supported up to 13 MP.

Power Consumption

Due to the low clocked Cortex-A7 cores and the small GPU, the SoC is using not much power and therefore also suited for small tablets.

Mediatek MT6592

The MediaTek MT6592 is a mid-range 28 nm SoC for Android smartphones and tablets. It was announced near the end of 2013 and is manufactured in 28 nm. It includes 8 Cortex-A7 processor cores that are typically clocked up to 1.7 - 2.0 GHz. Furthermore, the SoC integrates an ARM Mali-450 GPU at 700 MHz, WLAN, a video decoder for up to 4K content, a LPDDR3 memory controller at 666 MHz, and a 2G/3G (UMTS/HSPA+) radio.

Although the MT6592 offers eight relatively high clocked CPU cores compared to other SoCs, its performance in day-to-day usage is a bit lower, as the Cortex-A7 cores offer slower performance per clock and only a few apps are able to make use of all 8 cores simultaneously. Modern dual-core (e.g., Apple A7) or quad-core (e.g., Cortex A15 or Snapdragon 800) SoCs can be clearly faster in everyday scenarios.

The integrated ARM Mali-450 MP4 GPU offers 4 graphics clusters that are clocked at a high 700 MHz. However, the performance of the GPU is somewhat below that of a Tegra 4 or Adreno 320. Also like the Nvidia rival, the Mali-450 lacks support for OpenGL ES 3.0.

MediaTek MT6572

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.
