Xiaomi's product line has long gone beyond mobile phones. After the launch of mobile phones, televisions, boxes, routers, mobile power supplies, headphones and other products, Xiaomi finally launched its own tablet products. In addition to continuing the cost-effective route, the Xiaomi tablet also uses Tegra K1 processor on mobile products for the first time, bringing unprecedented strong performance. We also got the engineering machine of Xiaomi tablet. Let's see how its experience is:
Unpacking
The packaging style of Xiaomi flat is the same as that of Xiaomi products in the past. It is still packed in yellow paper boxes, of course, the volume is much larger ▼
Open the package to see the millet plate, with a piece of plastic film for protection ▼
The second layer of the package is the accessories of the millet plate ▼
The accessories of Xiaomi tablet are very simple, such as data cable, power adapter, clip and related instructions ▼
The charging current of the power adapter is 2A, and the battery capacity of the Xiaomi tablet is 6700mAh. It really needs a larger current to shorten the charging time ▼
The front of Xiaomi plate is relatively simple, with black panel design ▼
Xiaomi's logo is in the upper left corner, light sensor and distance sensor are on the right side of the logo, and the front 5 megapixel camera ▼ is in the center of the top
The virtual key widely used in Android tablet does not appear on Xiaomi tablet. Instead, there are three touch keys with white backlight, namely multi task management, home key and return key. Among them, long press multi task can realize the function of menu key (settable), long press home key and return can be set to close the current task ▼
What we got is the white version of Xiaomi flat panel engineering machine. The back adopts the high gloss injection molding process. The whole back cover is smooth and smooth. It feels very similar to the iPhone 5C ▼
There is a rear 8 megapixel backlight camera in the upper left corner, and a microphone ▼ is below
Xiaomi flat plate adopts double speaker design and is installed below the back ▼
3.5mm headphone connector ▼ on the top
There is a Micro USB interface at the bottom, and there is metal protection ▼ near the interface
On the right side of the fuselage is the electroplated paint button, on the top is the volume button, and on the bottom is the power button ▼
Micro SD card slot is on the left side of the fuselage, which can be ejected by using the built-in pin ▼
UI
Xiaomi tablet uses the Pad version MIUI ▼ specially customized by Xiaomi
The initiator and mobile MIUI are very similar, but the Pad MIUI cannot add widgets at will ▼
Shortcut switch ▼ displayed in the drop-down bar
The leftmost page of the launcher is dedicated to placing widgets. Here we can add built-in clock, calendar, calculator and other components, or add some third-party plug-ins ▼
The setting menu of Xiaomi tablet adopts white as the main tone, and adopts the menu layout of left and right columns ▼
The system version of the Xiaomi tablet is Android 4.4.2, and the kernel is relatively new. The version is 3.10.24 ▼
Various user-defined ▼ keys are supported
We got the 16G Xiaomi tablet, and the usable capacity of 16G Rom is 13.46G ▼
There is no ART mode option in developer options ▼
Press the multi task key to open the task manager, which supports one key to close all tasks ▼
Built in calculator application ▼
compatibility
In fact, there is no traditional compatibility problem for Android tablets. Even Android phone applications can run normally on Android tablets. The bigger problem of Android tablet is the adaptability of the application, especially for Xiaomi tablet, the 4:3 high resolution screen will bring a lot of trouble. When the Xiaomi tablet was released, it announced that it would work closely with application manufacturers to solve the application adaptation problem. Let's take a look at the current situation:
There is no doubt that the experience of the built-in Xiaomi Mall is very good, and the entire interface also conforms to the specifications that Android applications should have ▼
Built in multi view reading HD (targeted adaptation), perfect operation ▼
Read more screenshots of HD reading ▼
In the Xiaomi application market, we can find a series of special applications for tablets. Of course, only a few of them are targeted for Xiaomi tablets. Let's download several applications to test ▼
Weibo HD (not for adaptation), which is an "old disaster" application of Android tablet, will be ugly for tablets with resolution above 1280 * 800, so the Xiaomi tablet will not be spared. The font and menu are too small. We hope Sina can update them as soon as possible to save the high-resolution Android tablet ▼
Because the adaptation of Weibo HD is a big problem, which seriously affects the use, we also try to install the mobile version of Weibo, which shows that the content of Weibo is not a big problem, but the layout is still uncomfortable. For the time being, we can only compromise ▼
The overall layout of the interface is normal due to the dictionary HD (not for adaptation), but the icon appears rough due to the high resolution, and some fonts are not fully displayed ▼
Zaker HD (targeted adaptation), perfect operation ▼
Chrome， As Google's own application, Xiaomi Tablet has no pressure to run ▼
At this stage, there are not many applications for Xiaomi tablet adaptation, and the experience of using Android applications with the "HD" suffix still lags far behind that of iPad. We can only hope that Xiaomi tablet can effectively "activate" high-resolution Android tablet applications.
performance
The Xiaomi tablet is the first device in the world to use NVIDIA Tegra K1 processor. The CPU is a four core Cortex-A15 architecture with a frequency of 2.2GHz, and it is matched with a 192 "core" Kepler architecture GPU. Such a specification has already belonged to an adverse level for a tablet. What about the performance of the Xiaomi tablet? Let's take a look at the actual measurement:
Xiaomi tablet is equipped with 2G memory, and 1.1G ▼ can be used when starting
Processor information, Tegra K1 code named Logan, A15 r3p3 version ▼
There is nothing to say in the evaluation of Anthare. It is easy to reach 40000 yuan. We are also expecting such a result. I'm afraid that only the Galaxy S5 with Exynos 5422 can compete with the first competition (reference: Snapdragon 801 runs 38000 points) ▼
Pi, the score of more than 27 seconds is not very top, but it is also an excellent score (reference: Dragon 801 score of 25 seconds) ▼
In RAR compression test, the score exceeds 1200KB/s, which is equivalent to Snapdragon 801, and still lags behind Exynos 5420/5422. This test tests the CPU's L2 cache performance (reference: Snapdragon 801 score 1243KB/s) ▼
The web page javascript performance Sunspider 1.0.2 was tested with Chrome beta, and the result was good, but it did not meet our expectations for high-frequency Cortex-A15 (reference: Snapdragon 801 score 695ms, the lower the score, the better) ▼
The GBA simulator has an excellent performance, but it is only comparable to the 1.9GHz quad core Cortex-A15, and still does not show the advantage of high frequency (reference: Snapdragon 801 170 frames) ▼
A1 SD Bench， Test the speed of flash memory in the fuselage. Since the Xiaomi tablet uses eMMC4.5 chips, reading and writing are not as fast as eMMC5.0 supported by Snapdragon 801 (reference: eMMC5.0 chip reads 220MB/s and writes 58MB/s) ▼
Video software decoding test (1080P FPS60 ref=15 mp4 video). BSPlay is used for soft decoding. The average frame number is 47, which is not very high (reference: Snapdragon 801 average frame number is 50). From this screenshot, it can also be seen that due to the 4:3 screen, when watching 16:9 video, the Xiaomi tablet will have a black edge ▼
Use the frequency detection application to check the frequency. In the video of more than one minute, the CPU of the Xiaomi tablet can basically keep above the 2GHz main frequency, which performs well, but the number of frames is not high. This situation is somewhat puzzling ▼
In the GFXBench 3.0 graphics performance test, Tegra K1 finally showed a dominant performance. In the off screen test on the right side, Tegra K1 left its competitors by a wide margin (reference: Snapdragon 801, 11 frames in Manhattan, 28 frames in Tyrannosaurus Rex). The number of frames is twice that of the top Snapdragon 801 in mobile phones, and the graphics performance is very powerful. Even in the open screen test on the left side (considering the body resolution), the frame number of the Xiaomi tablet still exceeded that of the iPhone 5S, which is famous for its graphic performance, in the T-Rex test, showing its horrible graphic performance ▼
3DMark, the Xiaomi tablet still shows the impressive graphics performance of Tegra K1, even more than 200 frames in the test of the first scene, which is the horrible performance we have never seen in previous tests ▼
Top SoC graphics performance comparison table:
With such powerful graphics performance, we also used the game to test the Xiaomi tablet. The real car 3 did not achieve the highest special effect. It is estimated that the game has not been well adapted to Tegra K1. Of course, the fluency is not a problem at all ▼
Extraordinary Spider Man 2, also failed to achieve the highest special effect, the ground lacks dynamic blur, and the smoothness is very high ▼
The Shadow Gun, because most Android devices are widescreen, many games are also adapted to this resolution. As can be seen in the figure below, part of the game menu has been cut ▼
The actual picture of the game performs well with high fluency ▼
More tests and experiences of Xiaomi tablet will be introduced in detail in the next evaluation.
