Mediatek MT8127 vs Mediatek MT8321 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 MT8321

The Mediatek MT8321 is a low-cost ARM SoC (System on a Chip) mainly used in smartphones. It is most likely manufactured in 28 nm and integrates a quad-core Cortex-A7 processor and a ARM Mali-400 MP2. The CPU cores are clocked at up to 1.3 GHz while the GPU is clocked at up to 500 MHz. Furthermore, the chip includes a EDGE / HSPA+ / WDCDMA radio and 802.11 b/g/n WiFi. The integrated single channel memory controller supports LPDDR3 RAM.

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.

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.
