MediaTek MT6589 Is on two thousand and twelve year twelve New four cores released in June Cortex-A7 Architecturally SoC ， CPU The dominant frequency is 1.2GHz , the graphics processor is PowerVR SGX544 。 And its first mobile phone TCL Y900 It has been released. Now let's open it MT6589 The veil of mystery.

TCL Y900 parameters

CPU MT6589 (based on MT6589) 28 nanometer process quad core 1.2GHz

RAM 1GB

ROM 4GB supports tf card expansion

Screen 5 inch 1280x720 resolution IPS (full fit)

Camera 8 megapixel rear+LED fill light

Body size 144x75x8.5mm

Operating system Android 4.1.2

SIM card type Micro SIM card (WCDMA/GSM+GSM dual card dual standby)

Battery 2500mAh network system

In terms of parameters, Y900 has reached the current mainstream level. Of course, what we want to know most about the whole machine is the new MT6589 chip. What will its performance be like?

appearance

The appearance of the TCL Y900 is simple and fashionable. The front is a whole piece of black, and only the front camera and earpiece can be seen. The fully fitted screen also makes the front of the body look very black ▼

However, due to the thick border, some users will feel some pressure when holding it with one hand ▼

The back cover is integrated with the frame, and the white paint looks fashionable ▼

On the left side of the fuselage are two micro SIM card slots and micro USB interface ▼

On the right is the volume key and Micro SD card slot ▼

The top of the fuselage is the key switch and 3.5mm interface ▼

In terms of screen, Y900 uses a 5-inch 720P screen, combined with full fit technology, and is at a high level in screen performance. What's not good is that virtual keys occupy a certain amount of screen space ▼

System and software

Y900 uses a system based on Android 4.1.2. There are three virtual keys at the bottom of the screen. The system UI has not been deeply customized, and it is basically no different from the native Android 4.1.2. The built-in launcher is basically the same as the native system, but the Google search bar has been replaced with Baidu search bar ▼

Y900 has some unique plug-ins built in, among which the more creative is the clock plug-in handwriting search, which can quickly search the software and contacts in the machine. Of course, it would be better if the recognition speed could be improved a little. ▼

The lock screen is also very similar to the native Android 4.0 ▼

Program menu, some built-in software, commendably, these software can be deleted freely, even TCL's own software can be uninstalled, which seems more humanized ▼

Built in software market ▼

TCL flash transmission, which is a wifi direct connection file transmission software, can provide a much faster transmission speed than Bluetooth ▼

TCL results, similar to a shortcut to the search bar, use bing as the search engine ▼

performance

I believe everyone is interested in the performance of the MT6589 of MediaTek. The MT6589 uses a quad core processor with a Cortex-A7 core, a GPU with a PowerVR SGX544, and 1G of RAM. The following is the performance evaluation of the MT6589.

Theoretical test

We use some common scoring software to test the performance of Y900.

The score of Antu rabbit is close to 13000, which is higher than that of the previous test due to its relatively high frequency Quanzhi A31 The GPU is a bit higher, but also because the GPU is a single core, so in graphics processing ▼

GLBenchmark 2.5.1

Use the offscreen mode in GLBenchmark to test, and the number of frames is at the same level as the Geforce ULP of Tegra3 ▼

GPU performance test NenamarkV2.4

Since the GPU of the Y900 uses a single core SGX544, there will be some pressure when dealing with the 720P resolution. The frame number is about 39 fps ▼

Vellamo

Although A7 is adopted, its score is not low, and it is not far from the high-end A9 quad core and krait quad core ▼

Sunspider

Test with Baidu Browser+T5 core. From the test results, the web page performance of the quad core A7 is good. If the frequency can be improved, the gap with the high-end quad core will not be too big ▼

Software decoding

The soft solution test uses 1080P ref=16 fps=60 mp4 video for soft solution test. The frame number is 24, which is close to the performance of HiSilicon K3V2 ▼

Actual operation video

From the actual operation video, what impresses the author most is the smoothness of operation. For a Cortex-A7 architecture processor, although there is a certain gap between the theory and the common Cortex-A9 processor, the smoothness of Y900 is really good, and the smoothness in daily operation is comparable to high-end quad core products. In particular, the browsing smoothness of the browser is quite high. Y900 can have such an experience. On the one hand, it is close to the original Android 4.1.2, which provides a good platform to play. On the other hand, it is really commendable that Y900's own software has been optimized.

summary

As the first mobile phone with MT6589 chip, the overall performance of Y900 is satisfactory. The overall design and workmanship of the fuselage are quite careful. The 5-inch high-definition screen has a good guarantee of display effect and fineness. The most surprising thing is Y900's performance in smoothness. With a system close to native Android and excellent optimization, the response speed and smoothness of the whole machine are at a very high level. TCL's built-in series of software industries are quite unique, especially the clock plug-in handwriting search function is very novel. For a mobile phone with a 5-inch screen, the 75mm width is slightly higher. It would be better if the narrow border design could be added to the next generation of products.
