Mediatek MT8121 vs Mediatek MT6589T vs Mediatek MT8389

Mediatek MT8121

The Mediatek MT8121 is a low-cost ARM SoC (System on a Chip) 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 1.3 GHz while the GPU is clocked at 156 MHz.

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.

Features

In addition to the processor and GPU, the SoC integrates a decoder for 1080p video, WiFi, Bluetooth 4.0 as well as GPS, but lacks a 2G/3G/4G radio. 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 likely very low and suitable for even smaller tablets.

Mediatek MT6589T

► remove from comparison

The Mediatek MT6589T is a low-end system-on-a-chip (SoC) found in many inexpensive smartphones. It is manufactured in 28 nm and integrates a Cortex-A7-based quad-core CPU clocked at 1.5 GHz, a PowerVR SGX544 GPU clocked at 357 MHz, dual SIM and UMTS/HSPA+ support (up to 21 Mbps) and 1080p30 video decoding and encoding.

Both the CPU and GPU offer performances similar to an Nvidia Tegra 3 or the Samsung Exynos 4412 and Mali-400 GPU. Performance-per-clock of the Cortex-A7 is only slightly below that of a Cortex-A9, which can be found in the two aforementioned rivals. The graphics unit offers sufficient power for multimedia tasks and simple games, but not for extremely high resolution displays or complex 3D graphics.

Thanks to the modern 28 nm manufacturing and comparatively low performance, the power consumption of the entire chip is likely very low in order to be compatible with smaller smartphones and battery capacities.

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.
