MediaTek, founded in 1997, is the world's top professional IC design company. In the boom period of functional phones, MediaTek created the fake phone industry in Shenzhen by virtue of low-cost functional phone solutions, and even had a direct or indirect impact on the world's major mobile phone manufacturers. After the rise of smart phones, MediaTek began to decline due to the wrong decision on the route. Fortunately, the senior management timely reversed the direction and launched MT6575/6577 and other products for Android system, which again gained market recognition.
By virtue of "Turkey Solution", a "nanny service", MediaTek integrates chips and software, greatly reducing the technical threshold for mobile phone research and development, and attracting a large number of mobile phone design companies and terminal manufacturers to develop mobile phones based on MediaTek's chip platform. This practice has continued from the era of functional machines to the present and has become a major feature.
With the introduction of quad core chips by Qualcomm, nVIDIA and other manufacturers, MediaTek has also accelerated its research and development. Recently, it revealed a quad core architecture chip called MT6589, which is expected to be mass produced as soon as next year. It is reported that MT6589 is the MT6588 mentioned before, which was renamed for some reasons, but generally speaking, it should be similar. Parameter introduction:
MTK6589
Architecture: Cortex-A quad core
Process: 28nm
Frequency: 1.0GHz~1.2GHz
Memory: support LDDR2 memory
Screen: support 720P display resolution
Network: support WCDMA/TDSCDMA dual network system
Video: support 1080P video decoding support HDMI 3D output
Camera: support a camera with a maximum of 13 million pixels
GPU：PowerVR SGX 544， Triangle output rate is 55M/S, pixel fill rate is 1600M/S
Cortex-A7
The ARM Cortex-A7 processor belongs to the Cortex-A series and is based on the ARMv7-A architecture. Its feature is that it provides excellent low-power performance while ensuring performance.
Cortex-A7 architecture
The architecture and function set of the Cortex-A7 processor are identical to those of the Cortex-A15 processor. The difference is that the microarchitecture of the Cortex-A7 processor focuses on providing the best energy efficiency, so the two processors can be used in the big The LITTLE (Large and Small Core Companion Structure) configuration works together to provide the ultimate combination of high performance and ultra-low power consumption. The energy efficiency of a single Cortex-A7 processor is five times that of the ARM Cortex-A8 processor, and its performance is improved by 50%, while its size is only one fifth of that of the ARM Cortex-A8 processor.

Imagination PowerVR SGX 544
Imagination's new generation of mobile graphics core PowerVR SGX5XT (including 530/535/540/543/544) belongs to the fifth generation of PowerVR products. It adopts a unified architecture and supports DX9, SM3.0，OpenGL 2.0， It still uses the advanced TBR rendering mode and supports H264 hard decoding.
PowerVR SGX544 belongs to the Imagination PowerVR Series5XT family, and is also the second member of the family. Based on the second generation of universal scalable coloring engine (USSE2), it supports 2D, 3D, and GPGPU processing. It can be configured as a single core of high-performance four pipelines, or flexibly configured as a dual core to 16 cores (8-64 pipelines). However, in practical applications, the power consumption is generally not too much.
product positioning
According to past experience, MT6589 will replace MT6577 as the mainstream configuration next year, and the price will be 100-200 dollars, mainly for the low-cost quad core smartphone market. After the product is launched, it will have a certain impact on the current four core pattern and further compress the market price of domestic smart phones.
In addition, Qualcomm also launched the MSM8225Q/8625Q processor for the entry-level market. However, it uses the A5 architecture and only supports 720p video decoding. The performance advantage is not obvious and the threat to MT6589 is not significant.
Application examples
Recently, a Lenovo mobile phone suspected of being MT6589 was exposed, but the specific model is unknown. According to the screenshot, the machine is equipped with MT6589 processor, the highest frequency is 1.2GHz, the graphics core is 300MHz SGX544MP, it has 1GB RAM memory, it is equipped with 960X540 resolution screen, and it also supports TD-SCDMA and dual cards.

In addition, it is said that TCL and Jinli mobile phones have also started the MTK6589 quad core mobile phone planning of MediaTek, which may even be launched earlier than Lenovo. It is conceivable that next year, four core mobile phones will become mainstream at the price of 1000 yuan.
