Mediatek MT6582 vs Mediatek MT8321 vs Mediatek MT8389

Mediatek MT6582

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 MT8389

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.
