Mediatek MT8389 vs Mediatek MT8127
Mediatek MT8389
► remove from comparison
The Mediatek MT8389 is a low-cost ARM SoC (System on a Chip) used 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 1.2 - 1.5 GHz, while the GPU is clocked at 300 MHz. The official specifications of the MT8389 are identical to the MT8125 SoC.
Performance
Since the Cortex-A7 architecture is somewhat slower than a Krait or Cortex-A9 design at the same clock speed, the performance of the MT8389 is just below Nvidia's Tegra 3 or the Samsung Exynos 4412. The PowerVR SGX 544 is also just a simple low-cost solution not designed for ultra-high resolution displays or very demanding games.
Features
In addition to processor and GPU, the SoC also integrates a decoder for 1080p video, WiFi, Bluetooth 4.0, FM radio, GPS and 2G/3G radios (up to HSPA+). 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 low enough to be a fit for tablets.
Mediatek MT8127
► remove from comparison
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.
