Xiaomi Mobile 3 was officially released on September 5, and this time Xiaomi 3 uses two top platforms at the same time: And MSM8974AB, of which the former is used on the mobile version and is the first mobile phone of Tegra 4. The strength of Tegra 4, we have been in Toshiba After experiencing it on the tablet, what effect will it have on the mobile phone? Let's discuss it together.
From the configuration point of view, the biggest highlight of Xiaomi3 mobile version is undoubtedly the SoC. The addition of Tegra 4 makes Xiaomi3 have unprecedented powerful performance. Other configurations such as 5-inch 1080P screen, 2G Ram, 13.1 million stack camera and other features are basically what mainstream high-end mobile phones should have, so it's not surprising. Xiaomi 3 can achieve 3050mAh large capacity battery at 8.1 mm, which is also a big highlight ▼
The following evaluation only represents the situation of Xiaomi 3 Project Commemorative Edition (mobile TD network), and the actual version on the market may be different.
appearance
I believe everyone is familiar with the shape of Xiaomi 3. More photos can be seen 。
From the perspective of shape, Xiaomi 3 has changed from the previous sleek shape of Xiaomi mobile phones. This time, the body line has become very strong. Of course, the body also tends to be flat design ▼
Due to the large battery capacity and small body thickness of Xiaomi 3, we need to make a compromise on the area. We can see that its frame is wider than other mobile phones ▼
There is a small earpiece on the top. The front 2 megapixel camera is placed on the right, and the left is the light sensor and distance sensor ▼
Xiaomi 3 still uses three touch keys, namely menu, home and return, and all of them can emit light ▼
What we got is Xiaomi 3 of "Yahei", which is also the most low-key one among many colors. The back is frosted design, and the back cover is plastic material ▼
The camera is placed in the upper left corner. This is a 13 million pixel Sony stack camera with two led fill lights. Compared with 2S, the sensor parameters are the same, but a fill light ▼ is added
Reflective logo with electroplated texture. The following details show that this is a TD version of Xiaomi 3 (using 1.8GHz), supporting TD-SCDMA and GSM networks. This is also an engineering commemorative edition (300 sets in total, each with an independent number) ▼
3.5mm headphone jack, noise reducing microphone and SIM card slot ▼ on the top
The card slot can be easily opened through the supplied card needle, and the standard SIM card design is used. Lei Jun said that this design is more suitable for Xiaomi's user group and can avoid the trouble of cutting cards. But from a small point of view, microSIM is still the mainstream standard for high-end mobile phones. Using a smaller SIM card slot can free more space to increase the battery capacity, or make the body design more compact ▼
The bottom is the speaker and microUSB interface, but the USB interface still has no "foolproof" design ▼
The key layout on the side of the fuselage is the same as that of Xiaomi 2. The surface of the key is frosted and painted, and the key position is also suitable for single hand operation ▼
screen
Xiaomi 3 uses a 5-inch 1080P IPS screen, and the screen panel is provided by Sharp and JDI. The 5-inch 1080P screen is also used by many flagship mobile phones. The screen PPI has reached 441, and the picture fineness is not a problem at all. We are more concerned about the performance of Xiaomi 3 in screen color and visual angle. For comparison, we also selected two other high-end mobile phones as reference objects, namely LG G2 using AH-IPS and Samsung Super AMOLED 。 Their resolution is 1080P.

Solid color contrast (left G2, medium and small meter 3, right E330S) ▼
White is the strength of IPS, and the E330s of Super AMOLED is a bit horrible here. Compared with G2 and Xiaomi 3, the former is cold and the latter is warm.
Solid color contrast (left G2, medium and small meter 3, right E330S) ▼
Of course, Xiaobian didn't take away the mobile phone on the right... Black is the traditional strength of Super AMOLED, while G2 and Xiaomi 3 have light leaks in the lower left corner and the lower right corner respectively.

IPS screen always performs well in visual angle. The following is Xiaomi 3's visual angle test ▼
After the above tests, it can be seen that the quality of Xiaomi 3's screen is excellent, and its performance is more balanced.
UI
The system of Xiaomi 3 is still MIUI V5. Of course, it adds some special functions ▼ on the basis of 2S
Here you can see the system information. The processor is Tegra 4 1.8GHz, the memory is 2G, and the system is based on Android 4.2.1 ▼
The available ROM capacity is less than 10G. It is recommended that users with good money should go directly to 64G ▼
Power on available RAM exceeds 1G ▼
MIUI V5 still consumes RAM. After simple use, the available RAM often drops below 400M ▼
We won't describe other features of MIUI in detail here, but only show some unique functions of Xiaomi 3:
Among the displayed options, Xiaomi 3 has added glove mode, which is also the ultra sensitive touch screen technology ▼ used by many high-end mobile phones
Xiaomi 3, like Xiaomi 2A, has added NFC function ▼
In terms of sound effect, Xiaomi 3 adds Mi sound to enhance sound effect, while Xiaomi 2S uses ▼ of Dolby sound effect
performance
Of course, the performance of Xiaomi 3 is the focus of this evaluation. What new surprises will Tegra 4 bring when it first lands on the mobile phone? Let's take a look through the actual measurement.
The mobile version of Xiaomi 3 is used here. It is equipped with Tegra 4 1.8GHz (CPU-Z is marked as Tegra 2 due to identification error)+2G Ram. The GPU is Geforce ULP (72 "core"). It is particularly noted that Tegra 4 also has different models, among which Xiaomi 3 uses AP40, which has a certain reduction in specifications, and is known as the "nuclear bomb handheld" Tegra 4 with high-frequency 1.9GHz "full blood version" code T40 is used.
Theoretical score
Angu rabbit evaluation V3.4
In the evaluation of commonly used running points, the Xiaomi 3 mobile version scored an unprecedented high score. The score of nearly 37000 is definitely the most powerful model in mobile phones. In particular, the CPU's integer performance and floating point performance are significantly ahead of its rivals. In particular, the floating point performance score has exceeded 12000, which is beyond the reach of top chips such as Exynos 5410 and MSM8974. But when we look at the 3D drawing performance, there is no big surprise. It is even lower than the SGX544MP3 on Exynos 5410. The gap between it and Adreno 330 is still large ▼
We also tested the latest Anthare V4.0, and also ranked top in score. Compared with Exynos 5410 and Snapdragon 800, the main advantages are multitasking and CPU floating point performance ▼
Vellamo
This is a web testing software launched by Qualcomm, which mainly tests the HTML5 performance of mobile phones. Xiaomi 3 mobile version performs well, which is obtained in HTML5 test High score of 2824 , than E330S (2442) and I9500 (2071) All high ▼
Due to the server problem during the test, two items cannot be carried out. If the complete test can be passed, the score of Xiaomi 3 will be higher ▼ than that in the screenshot
Pi
In the evaluation of Anthare, we were deeply impressed by the floating point performance of Xiaomi 3 mobile version, while in the Pi test, its performance was not very ideal, and 1.6GHz Exynos 5410（32s） Similar ▼
CPU general performance test
Sunspider 1.0.1 (tested with Chrome Beta V30)
This web Javascript test is also often used in mobile phone evaluation, and the Cortex-A15 core has always been an absolute advantage in this test. Of course, Tegra 4 is also an expert in this field. With 1.8GHz high frequency, Xiaomi 3 mobile version successfully broke the 600ms barrier 595ms The test is completed with excellent results, and the performance is better than Exynos 5410 (612ms) and MSM8974 (710ms) Excellent ▼
Google Octane V1 (tested with Chrome Beta V30)
Similar to Sunspider, it is also a web page javascript test. Xiaomi 3 mobile version is still eye-catching in this test, The score reached 5363 ▼
Software decoding
Video software decoding is also an important test item to measure the general performance of the CPU. This test item tests the multithreading performance of the CPU, which is different from the video hard solution. It is a method to test the general computing power of the CPU, and multi-core processors will be used. The following tests use BSPlayer version 1.9.153, and the video used is 1080P ref16 FPS60 MP4 video ▼
Xiaomi3 mobile version software has good decoding ability, with the average frame number exceeding 41, fully demonstrating the strength of high-frequency A15.
GBA simulator
Using the built-in Benchmark of GBA.emu (1.5.12), the test object is a 14KB bios.zip. This test can more accurately reflect the CPU's computing power. Xiaomi 3 mobile version performs very well in this test, reaching 163 frames , Reference: E330S: 152 frames, I9500: 142 frames ▼
GPU graphics performance
Tegra 4 uses the new "72 core" Geforce ULP. We are also looking forward to the performance of this GPU. What is the performance of this GPU with the 1080P screen?
GFXBench 2.7.2
In the GFXBench test, the Xiaomi 3 mobile version performed well. Both 2.5 and 2.7 significantly exceeded the SGX544MP3. Of course, there is still a gap between it and Adreno 330 ▼
3DMark
3DMark updated the new version on September 9, and the test standard has changed. The latest Ice Strom Unlimited mode used here has also shown strong strength, with a total score of nearly 15000 ▼
Basemark X
In the Basemark X test, the performance of Xiaomi 3 mobile version's On Screen and Off Screen is almost the same, both exceeding 10 frames, which is also higher than that of the I9500, but there is still a big gap with the E330s ▼
In the graph test summary, Tegra 4 shows a strong graph performance. Here we also choose the strongest competitor Compare. It can be seen from the comparison chart that the 3D performance of Tegra 4 is still a little lower than that of Adreno 330 (450MHz), but such performance is no less than that of other mobile phones. This also makes us look forward to the Adreno of China Unicom and China Telecom 330@550MHz ）Graphic performance ▼ of
game
We have tested the Tegra 4 tablet, but the resolution is too high to run large games, and the Xiaomi 3 resolution is the mainstream 1080P, so this test is also very comparable. Tegra 4 uses the "72 core" Geforce ULP, which is six times that of Tegra 3. However, since it still uses separate rendering, the architecture of the GPU of Tegra 3 has not changed much compared with that of Tegra 3. It is purely "stacking", so the specifications are not surprising. What about the actual performance of Xiaomi 3? Let's have a look.
PS: Due to compatibility problems, the frame number detection software FPS Meter on Xiaomi 3 can't display the average frame number, so we can only measure the smoothness by looking at the real-time frame number plus "visual inspection".
Wild Racing 7 Shanghai Track
Although many players have passed the pass of Wild Speed Racing 8, Wild Speed Racing 7 still has its unique charm. For the test game, the Shanghai track of Wild Speed Racing 7 is also a test project with great pressure on GPU.
From the perspective of special effects, Xiaomi 3 mobile version is a high special effect, with complete body reflection and tire smoke effects, and satisfactory frame number performance, On average, it can approach 40 frames in the first lap, and the whole process is kept at more than 30 frames, so it runs smoothly However, the frequency is reduced at the beginning of the second cycle, and the number of frames will also decrease ▼
Wild Speed Racing 8
It is believed that there is no need to explain this super masterpiece. The special effects of the scene are better than those of the previous generation. Xiaomi 3 mobile version can basically guarantee high image quality 30 frames or so ▼
Top Speed Car 17
Top Speed 17 is also a commonly used project in game evaluation. Xiaomi 3 mobile version is on special effects Lack of dynamic blur , the fluency is not a big problem, Average 40 frames ▼
Modern Warfare 4
Modern Warfare 4 is also a regular customer of game evaluation, and it also has high requirements for the GPU of mobile phones. Xiaomi 3 mobile version is satisfactory in the performance of special effects, but the performance of frame number is not very stable. Most of the time at the beginning of the first stage Below 30 frames ▼
Real Racing 3
Frames in About 50 frames , running smoothly (the average frame number here is not displayed correctly, which can be ignored) ▼
Rapids 2
Rapids have always been Tegra's "royal game", and the specific performance is of course the exclusive special effects. While other mobile phones of Rapids 2 can only drive to Medium on the Shader, only the equipment of Tegra 4 can drive the highest special effect.
It is puzzling that the Shader of Xiaomi 3 mobile version using Tegra 4 can only be driven to Medium, that is, the special effect performance is the same as that of other mobile phones ▼
Very good in terms of fluency, the number of frames can basically reach About 40 frames ▼
The performance of Xiaomi 3 mobile version can be seen in combination with the following videos. The video content is about the frame number of Modern Warfare 4, NBA 2K13, Wild Racing 8, and the frequency reduction of soft video CPU ▼
From the video, you can see the changes in the number of frames of several large games (shown in red numbers on the upper right corner of the screen). In terms of frequency reduction, the phenomenon of high temperature frequency reduction began to appear at the end of a minute and a half of video playback, and dropped to about 1.1GHz at the lowest time.
In addition to regular game masterpieces, we have to mention all kinds of Tegra exclusive games, and Xiaomi also opened NVIDIA in the game center Tegra Game Zone. Here we can find some specially optimized games, and even some games are launched by NVIDIA, obviously to show Tegra 4's own special effects advantages. Xiao Bian also installed several special games such as rampage, gunfire battle line, hero summoning, etc. for testing ▼
Hero summoning ▼
Shotgun ▼
During the test, the quality of the game in this area was good, and the fluency was high enough. Of course, different people have different opinions on the playability.
Video decoding
Tegra 3's hardware decoding capability has impressed us deeply, and Tegra 4 will certainly inherit this tradition. We use mainstream 720P and 1080P video formats to test the hardware decoding of Xiaomi 3 mobile version.
Video list:
720P group

The test results are as follows:
The comparison table also takes other SoC mobile phones as a comparison, including the I9500 of Exynos 5410 and the E330s of MSM8974. By contrast, Xiaomi 3 mobile version performs well in terms of hard solution performance, but strangely WMV cannot be hard solved The editor tried to bring his own browser, and the latest version of BSPlayer and MXPlayer could not play normally. This should not be because Tegra 4 does not support WMV hard solution, because the editor can normally hard solution WMV video when testing AT703 before this. I hope that the Xiaomi 3 mobile version can play normally after upgrading the software. The hard solution performance of other videos of Xiaomi3 mobile version is completely consistent with that of AT703.
photograph
Xiaomi 3 uses the same Sony stack 13 megapixel camera with aperture F/2.2 as Xiaomi 2S (32G). Xiaomi 3 has also added many camera functions, such as manual focusing, RAW format, real-time HDR and other professional functions. Of course, multi-function is not enough. We also have requirements for the quality of mobile phones in photos. For comparison, LG G2 is also used as the contrast object. G2 uses 13 million cameras, aperture F/2.4, and three-stage OIS optical anti shake. The following is a comparison of some samples of Xiaomi 3 and G2:

G2 Daylight imaging (click to view the large picture) ▼
In this group of samples, Xiaomi 3 has better analytical power and G2 has more saturated colors.

G2 Daylight imaging (click to view the large picture) ▼
This group of proofs are similar to each other, but G2 is still attractive in color and can better reflect the luster of metal.
Xiaomi 3 dusk imaging (click to view the large picture) ▼
G2 Twilight imaging (click to view the large picture) ▼
This group of proofs both have the analytical power of 13 million pixels, and the difference is also in color performance.
Full manual mode
The full manual mode allows us to manually adjust the exposure, ISO, and white balance. In particular, we can adjust the shutter time up to two seconds. Next, we will also compare the shutter time of two seconds with that of shooting night scenes in the normal mode ▼
Xiaomi 3 automatic mode night view (click to view the large picture) ▼
Xiaomi 3 two second long exposure effect (click to view the large picture) ▼
It can be clearly seen that a 2-second exposure combined with a low ISO value can bring better picture purity, while the picture will not appear too dark, much better than the effect of automatic mode.
As a contrast, the following is a sample of the same scene of G2. G2 cannot view the shutter and ISO information after turning on the night view mode. The night view performance in this mode is between the automatic mode of Xiaomi 3 and the long exposure (click to view the large picture) ▼

Xiaomi 3 1/2 second exposure night scene sample (click to view the large picture) ▼
After manually lowering the ISO, a relatively long 1/2 second exposure can bring better picture purity, but this exposure time is difficult for handheld users. From here, we can see that the night view of Xiaomi 3 can be better played by adjusting the ISO and shutter speed with the help of the full manual mode. For ordinary users, such adjustment is slightly cumbersome and complicated.

From this group, it can be seen that G2 is better than Xiaomi 3 in terms of brightness and noise control in the night scene mode, but the color is yellow.

RAW format
I believe that friends who have used SLR or SLR should be familiar with this word. Taking pictures in RAW format means saving the pictures without the JPG algorithm in the machine. RAW format photos give users more space in the later stage. Of course, RAW format photos are relatively large in size and can only be processed by computers.
In machine jpg straight out sample (click to view large picture) ▼
RAW to JPG+color mixing sample (click to view the large picture) ▼
It can be seen that after color mixing of RAW photos, the color problem of Xiaomi 3 photos can be improved to a certain extent. Of course, in addition to color blending, RAW format can also be sharpened, saturated, reduced noise and other adjustments. There is also a small problem here, that is, the shutter speed of JPG straight out and RAW format is inconsistent.
Millet 3 sample (click to view the large picture) ▼
When it comes to taking photos, we have to mention taking photos of ourselves. Many mobile phones now emphasize the high pixels of the front camera. We can even see the front camera with 8 million pixels and 13 million pixels. Xiaomi 3 uses a 2 million pixel back facing front camera. Although the pixel is not high, the self portrait of Xiaomi 3 has a very interesting function, that is, it can be beautified to different degrees according to people's gender and age. Here are some simple tests.
When taking a selfie, you can automatically identify gender and age. Of course, the error is still a bit large. Guess what the real age of the sister paper in the picture is? ▼
Display age and age range can be set
Selfie sample ▼
consume power
Xiaomi 3 uses a large capacity battery of 3050mAh. Although its capacity is not comparable to some super large screen phones, this capacity is very large for 5-inch phones. We also test the endurance of Xiaomi 3 with some daily use scenarios. The test results are as follows (test environment: screen brightness 60%, volume 50%):
Half an hour large game (NBA2K13, automatic operation): 100% → 84%, Power consumption 16%
Half hour WiFi access: 84% → 78%, Power consumption 6%
Half hour 3G Internet access: 78% → 69%, Power consumption 9%
Half hour GSM call: 69% → 65%, Power consumption 4%
From the above tests, Xiaomi 3 mobile version is still satisfactory in terms of endurance performance.
signal
As the name implies, the Xiaomi 3 mobile version supports mobile 3G networks. Due to the reason of the base band of Spreadtrum SC8803G5, it only supports TD-SCDMA and GSM networks. This is determined by hardware, and it is impossible to support other networks through cracking. In actual use, Xiaomi 3's signal performance is good, and the GSM signal has always been good, but the TD-SCDMA signal is not ideal, and you can only access EDGE indoors. Of course, this is not entirely the problem of Xiaomi 3 mobile version. This is the case with most mobile 3G phones ▼
fever
Although TSMC 28nm HPL process is used for manufacturing (HKMG), the heating capacity of four high-frequency Cortex-A15 cores should not be underestimated. The following is our heating test for Xiaomi 3 mobile version (test environment: room temperature 27 ℃):
20 minutes for large games, The maximum temperature on the front is 44 ℃, and the maximum temperature on the back is 41 ℃ ▼
WiFi Internet access for 20 minutes, The maximum temperature on the front is 39.2 ℃, and the maximum temperature on the back is 37.1 ℃ ▼
On the whole, Xiaomi 3 mobile version is just so hot, but not as "enthusiastic" as expected.
summary
Xiaomi has always been famous for its cost performance ratio, which has not changed since the generation of Xiaomi 3. Judging from the appearance design of Xiaomi 3, the style is indeed different from the previous products. Xiaomi 3 takes the thin and light route and uses an integrated body, which shows its difference from previous generations of products.
In terms of hardware configuration, Xiaomi 3 has also reached the top level. The 5-inch 1080P screen+2G Ram+13 megapixel camera is also the "standard configuration" of many flagship phones. In addition to these, Xiaomi 3 has also taken the lead in using two top SoCs, Tegra 4 and MSM8974AB, and has taken the lead in performance. Specifically, on the Xiaomi 3 mobile version, Tegra 4 has indeed brought great performance improvements. The four core high-frequency Cortex-A15 has strong performance, and the 72 core Geforce ULP is also commendable. However, we should also note that because of the huge power consumption and heating of the A15 itself, the problem of high temperature frequency reduction will be relatively serious. In terms of game performance, Xiaomi3 mobile version is not a problem in dealing with the fluency of mainstream large-scale games. It also performs well in image quality. The only problem that affects the performance is the frequency reduction. After our actual measurement, Xiaomi3 mobile version stays at high frequency for about one and a half minutes, which will be reduced to the lowest 1.1GHz in the future, which will certainly have a certain impact on the operation of the game. Since we have not yet been able to detect the frequency of Geforce ULPs, it is not clear whether the high temperature frequency reduction is only a CPU problem or the GPU will also follow.
In terms of photographing performance, Xiaomi 3 can basically display the strength of 13 million stack sensors, and performs quite well in solar imaging. In the low light environment, Xiaomi3 has a lot of noise and needs further optimization. It is slightly slow in focusing speed. In terms of the playability of taking photos, the rear camera of Xiaomi 3 supports RAW, manual focusing, 2-second exposure and other playing methods, which can allow players to take more colorful photos. The 36 level front camera and the skin beauty of automatic gender and age recognition also make Xiaomi 3's selfie more playable.
In general, the performance of Xiaomi 3 mobile version can meet the needs of most people, and the performance is balanced in all aspects. Of course, the control of high temperature frequency reduction is not very good at this stage, and there is still room for optimization of system smoothness, but it is not easy for an engineering machine to achieve such an overall performance. For mobile users, the Xiaomi 3 mobile version is a very good choice. At the price of 1999 yuan, you can enjoy the top hardware configuration and use the TD network, which is cost-effective. Users with high requirements for graphics performance can consider waiting for Unicom of MSM8974AB and Xiaomi 3 of Telecom. I believe its 3D performance will never disappoint us.
