Unlike the flagship machine, the price of the new Snapdragon 660 has been falling all the time due to fierce competition in the middle end machine, many of which have reached about 1500 yuan. What's more, Xiaomi 8 SE, the first Xiaolong 710, set the starting price at 1799 yuan.
Snapdragon 710 will be the core upgrade point of mid tier computers in the second half of this year. This time, we will take a look at the comprehensive performance of the new SoC through the first model of Xiaomi 8SE. As usual, this evaluation will be carried out according to the core parts of "appearance, screen, performance, photography, and endurance".

Appearance and workmanship
List of accessories: manual warranty, card taking pin, silicone protective case, Type-C to 3.5mm interface, data cable, QC3.0 fast charging head. The charging head is the same as Xiaomi 8, the model is MDY-08-ES, the maximum output is 18W, and it is manufactured by Huizhou BYD.
Xiaomi 8 SE, Xiaomi 8, Xiaomi MIX 2, Xiaomi MIX 2S
It is rumored that this year's iPhone SE will be a glass back cover, but Xiaomi has already taken the lead in building an SE. The original meaning of "SE" refers to the flagship of the small screen. The appearance feature of the Xiaomi 8 SE is that the 2.5D arc is small, and the angled "total reflection" glass back cover can really be used as a mirror. From my aesthetic point of view, the most beautiful Xiaomi 8/8 SE of this generation is the bright blue.
This vertical double photography and back fingerprint are both "heritage design" of Xiaomi this year. Even if I don't like it, I guess I will change the design language next year.
Xiaomi 8 SE, Xiaomi 8 and Xiaomi MIX 2
Samsung AMOLED Liu Haiping, 5.88 "18.7:9 on the front, 2244 x 1080 (4 pixels less than Xiaomi8 vertically). Generally, the four corners of a Liu Haiping are big rounded corners, while the Xiaomi 8 SE is square in shape, and the rounded corners on the screen edge are very small, so the Liu Haiping is highly recognizable.
The width of the bangs is smaller than that of Xiaomi 8, and the number of icons displayed on the notice bar is a little more than that of Big Brother (about half of the icons are really a little bit). The lower border is obviously narrower than that of Xiaomi 8, but the side border is thicker than that of Xiaomi 8. In addition, the notice bar of MIUI 10 is wider than the fringe, which seems to be disharmonious. I hope OTA can help the notice bar slim down in the future, or provide options for similar functions. In addition, please put back the function of directly displaying the percentage of electricity.
The interface layout has not changed significantly, but the top infrared transmitter (small Mi8 and MIX 2S are not available). The power key has concentric circular lines, which is convenient for blind touch and identification.
It should be noted that there is no plastic washer between the back glass and the middle frame of Xiaomi 8 SE, but there is a washer at the screen edge, so the side view is asymmetric, which affects the feel of sliding screen edges, and improving the fall prevention performance is really costly.
Workmanship, feel and face unlocking
Xiaomi 8 SE The key feedback is clear and good, but we have this machine The keys have obvious false position, which affects the overall texture.
In terms of hand feel, the horizontal width of the Xiaomi 8 SE is similar to that of the previous 5.2 inch mobile phone, but the square shape, weight of 164g, and lack of radian on the back all affect the hand feel performance. Nowadays, mobile phones are becoming more and more slender, and it is difficult to touch the notice bar with one hand on Xiaomi 8 SE.
screen
Factory default adaptive mode, sRGB color standard
Test results in different modes
(The closer the color gamut is to 100%, the better the color temperature is to 6500K, and the smaller the color level delta E, the better)
Xiaomi 8 SE manual full white maximum brightness is 401 nits, the fringe area is 395 nits, and the bottom is about 416 nits. Full white automatic brightness, which can reach 540 nits under strong light, and the limit of shrinking area can reach 730 nits. There is nothing wrong with readability in the sun.
The default color temperature of Xiaomi 8 SE is about 7500K, and the cold screen. The color gamut is even wider than that of Xiaomi 8, which can break through the DCI-P3 color gamut and exceed the sRGB color gamut by nearly 50%. The effect is that in the default adaptive mode, its color is even more colorful than Xiaomi 8 in the same mode. However, the actual color accuracy is average (the sRGB color accuracy of the red rice series can reach about 2).
performance
If the Snapdragon 660 inherits many technical features from its previous flagship (Snapdragon 820/821) Snapdragon 710 has acquired the technology of flagship Snapdragon 845 of the same generation ：
The same 10nm LPP process as that of Snapdragon 845 was used;
The Hexagon 685 DSP of Snapdragon 845 is used;
The ISP is the Spectra 250 of the same generation as the Spectra 280 on the Snapdragon 845. It has a two-way 14bit camera. It supports up to 20 million pixels of dual photography, or 32 million pixels of single photography. It supports up to 4K30 frames of video recording;
Although the baseband is "only" X15 LTE, there are also Cat 13 uplink (150Mbps) and Cat 15 downlink (800Mbps), which support 4x4 MIMO;
The screen supports up to 3360 * 1440, or 2K+, and HDR10.
The performance we are most concerned about:
CPU part is 2 2.2GHz Kryo 360 Gold large core and 1.7GHz Kryo 360 Silver small core (based on A55) The Kryo 385 of Snapdragon 845 is based on the semi autonomous architecture modified by A75, while the Kryo 360 is based on Kryo 385 reduction/frequency reduction. Qualcomm claims 20% performance improvement The running score of Anthare increased by 22%, and the speed of web browsing increased by 25% and the speed of application opening increased by 15%.
The GPU is Adreno 616, the highest dominant frequency is 500MHz, and it is claimed to be improved by 25% , game and 4K HDR video playback power consumption reduced by 40%, and streaming media power consumption reduced by 20%.
In addition to CPU and GPU architecture ISP、DSP、 The baseband is not up to the level of rivals at the same level. "Invincible is the loneliest" is very suitable for describing the current Snapdragon 710 . However, from the configuration point of view, there are only two CPU cores, and the extent of multi-core performance improvement is worrying. and On the Xiaomi 8 SE, eMMC 5.1 flash memory is still used.
Performance comparison
In order to control the variables brought by the system and manufacturers, Xiaomi products are used uniformly this time. The comparison objects include the flagship of these two generations, Snapdragon 845 (Xiaomi 8) and Snapdragon 835 (Xiaomi MIX 2), Snapdragon 660 (Xiaomi Note 3) and Snapdragon 636 (Hongmi Note 5). Because Xiaomi 6X still has the limitation of multi-core performance output in the latest stable version system, Xiaomi Note 3 is used as the representative of Snapdragon 660.
CPU performance test:
Overall ranking: The CPU performance of Snapdragon 710 is about 1.3 times that of Snapdragon 636, 100-110% of Snapdragon 660, 90% of Snapdragon 835, and 70% - 80% of Snapdragon 845;
Single core performance: What's interesting here is that Qualcomm has 2.2G core frequency on Snapdragon 710 and 660, which is just convenient for us to compare the performance of the same frequency. The new architecture brings About 15% of the single core performance has been improved, and it almost meets Snapdragon 835. The stronger single core performance will bring some improvements to some games.
Multi core performance: In the Android platform that pays more attention to multi-core performance, multi-core performance is more valuable. But Qualcomm only gave two big cores, The multi-core performance is only competing with Snapdragon 660 (four big cores and four small cores). In the multi-core burst test required, Snapdragon 710 only led 660 in the RAR multi-core test by a small margin, but pi and GeekBench 4 multi-core test both lost to 660. It is hoped that the "low multi-core performance bug" can be corrected in the official version of the system.
GPU performance test:
In terms of GPU, Qualcomm is not so generous. There is a huge gap between different products. Snapdragon 710 is about twice as many as Snapdragon 636 and 1.4 times as many as Snapdragon 660, only about 50% of Snapdragon 835 and 40% of Snapdragon 845.
How to describe such GPU performance? It means that after stimulating the battlefield with high image quality, high frame rate and anti aliasing, it can only maintain 30 frames, and after reducing the image quality, it can maintain 40 frames of smooth operation.
Memory and flash performance test:
In terms of memory testing, Qualcomm's generation of Kryo 385/360 based on A75 has more serious memory latency than before, but multi-core performance in ternary combination testing is still growing at a high speed.
In terms of flash memory, including the unseen Xiaomi 6X, after the Hongmi Note 5, Xiaomi's random write performance test of flash memory this year has increased significantly, and its performance is closer and closer to that of the F2FS file system models.
But it's a pity that Xiaomi 8 SE, the Snapdragon 710, UFS flash memory is still not used, or eMMC 5.1 . Although this time we participated in the comparison of UFS models, their flash memory capacity is larger (under the same conditions, the larger the capacity, the faster the speed), we can not hide the gap between the two types of flash memory in terms of reading speed (continuous reading is almost 3 times, random reading is almost 2 times). The good news is that continuous read and write performance has less impact on daily use than random read and write performance.
Briefly summarize the performance of Snapdragon 710 The core improvement lies in single core performance and GPU ：
Compared with Snapdragon 660, its CPU The single core performance is improved by about 15%, but the multi-core performance, which is more significant for daily use, is almost unchanged . Not only did it not reach the official standard value, but also the range was so small that it was very suitable to use "squeezing toothpaste" to describe it. There are stronger large cores, but only two are given, which is obviously controlling the performance increase;
The GPU part needs a lot of sincerity, with an increase of 40% However, this increase is far from catching up with the previous flagship Snapdragon 835 (about 40% of the 835), let alone the Snapdragon 835. Qualcomm's poor positioning of Snapdragon 600 and Snapdragon 800 is very clear.
Of course, Android's CPU has long been a bottleneck, but GPU is still in the process of rapid growth, which has been recognized by the industry.
In addition to CPU and GPU, Snapdragon 710, network, ISP and DSP have improved significantly, but not as much as the previous Snapdragon 660 and 636. We seem to have been spoiled, but hopefully Qualcomm is not deliberately squeezing toothpaste.

Hardware and Analysis
According to the ranking analysis of the photo generation process, the reference of these contestants is interesting when they are put together:
Sensor and aperture (the bigger the better) : Except that Xiaomi 6X is 1.25 μ m, the rest are 1.4 μ m products. Among them, the IMX363 of Xiaomi 8/8 SE is more advanced than the Samsung S5K2L7 on Hongmi; The Xiaomi 6X with the smallest unit size has the largest aperture, Xiaomi 8 SE has no optical anti shake, and its aperture is smaller than Xiaomi 8;
ISP (Image Signal Processor) : Hongmi Note 5 is a Snapdragon 636, but its ISP and DSP are consistent with the Snapdragon 660 on Xiaomi 6X; Xiaomi 8 SE is a higher level. The Spectra 250 ISP of Snapdragon 710 is the same generation product of the Spectra 280 on Snapdragon 845;
Algorithms and systems: As of June 7, both Hongmi Note 5 and Xiaomi 6X are MIUI 9.5.7 stable version systems, while Xiaomi 8/8 SE are MIUI 10.5.30 development version (mass production machine is MIUI 9). Between these two generations of systems, Xiaomi has updated its own photography algorithm. During this period, there were two DxOMark percentage cameras, Xiaomi MIX 2S and Xiaomi 8.
Photography experience, wide angle, HDR and telephoto
The experience of Xiaomi 8 SE, such as the photographing interface, imaging speed and shutter response, is very close to that of Xiaomi 8 , but it has no optical anti shake, the frame is not as stable as Xiaomi 8, and the weak light rate is lower.
When the left side is aligned, the field of vision of Xiaomi 6X on the right side is smaller
Xiaomi's EXIF does not provide reliable equivalent focal length information, but it can be found in the actual film that not only the aperture and lens module (all of them are OFI light) of Xiaomi 8 SE are close to those of Hongmi Note 5, but even the setting of large wide-angle is the same. Their wide-angle is larger than that of Xiaomi 8, and even larger than that of Xiaomi 6X with a "telephoto" lens.
Enlarge the scene 5 meters away, and enlarge it proportionally
The advantage of large wide-angle is that the field of vision is large, but the same object will be smaller in the photo (that is, the unit scene can be divided into fewer pixels, the effect is as shown in the above figure), and the discrimination will suffer.
Comparison of Xiaomi 8 SE on and off HDR
Xiaomi 8 SE open and close HDR contrast, zoom in (pay attention to the light source and dark part)
Xiaomi 8 SE open and close HDR contrast, amplification
When the Xiaomi 8 SE is in weak light, the automatic HDR trigger is not as sensitive as the other three machines. The above two test scenarios are not triggered. This eliminates the need to worry about the automatic HDR switch.
Among the four machines, only Xiaomi 8 has a telephoto sub camera, which can be magnified and contrasted. Of course, there is no comparability:
2x magnification and contrast
Among them, Xiaomi 8SE and Hongmi Note 5 are the same sub camera, and the 5 megapixel S5K3E8 is responsible for the depth of field visualization. The Xiaomi 6X is the most special. Its 20 million pixel subphoto is a conventional focus segment. This kind of sub shot is generally used for digital cutting (2000W is cut into 1200W) when zooming, or for weak light imaging (pixel 4 in 1 technology), but the sub shot of Xiaomi 6X is not involved in zoom and weak light imaging, and is still used for depth of field virtualization (very wasteful), the situation is the same as one plus six

Summary
The metering, white balance and saturation of Xiaomi 8 SE are very close to that of Xiaomi 8, except that the primary color of 8SE is red, and that of Xiaomi 8 is yellow, but they are quite different from the styles of Note 5 and Xiaomi 6X. Limited by wide angle, Xiaomi 8 SE and Hongmi lost their daytime discrimination to Xiaomi 8 and 6X. But after the light became weaker, it was Xiaomi 8/8 SE. The brightness, tolerance and details were all crushed. The other two were beaten completely out of temper.
But the details of Xiaomi 8 SE are still far from Xiaomi 8 After all, the wide-angle is large, the aperture is small, and there is no optical anti shake. Here is a detail: the Xiaomi 8 SE will not trigger HDR as easily as the Xiaomi 8 SE under weak light, which will cause side effects. This is very good.
Endurance and charging
Xiaomi 8 SE is equipped with 3120mAh battery, and its endurance performance is not as expected. After 30 minutes of large-scale games (NBA 2K15), 30 minutes of wifi and 4G Internet access and 30 minutes of local video playback, a total of 2 hours of endurance testing, the remaining power is 76%. Although the battery capacity is also small, the 8 SE screen is also a bit smaller than the Xiaomi 8. It was originally expected to be similar to the Xiaomi 8, but the actual endurance is weaker than the same generation of Snapdragon 845 and Snapdragon 660 models. You know, this is only a two-hour test. If the time is prolonged, the gap will be doubled.
The zero load power consumption records (minimum brightness, flight mode) of Xiaomi 8 SE and Xiaomi 8 are about 560mW and 400mW respectively
A careful look at the small test project shows that its power consumption is higher than that of other comparison models in web browsing and video playing under low load. This may be because The base power consumption of mobile phones is higher In the previous power consumption test (see the figure above), the power consumption of Xiaomi 8 SE under zero load is indeed higher than that of Xiaomi 8, or even that of Hongmi Note 5 (Snapdragon 636, about 450mW).
The reason for the high basic power consumption is unknown. It may be because of Snapdragon 71, or it may be this Liu Haiping, other peripheral circuits or MIUI pots. Of course, this is not too bad. It is close to the level of Xiaomi 5 (Snapdragon 820) in the past two years, but the endurance growth of Android platform in the past two years is really too fast.
Xiaomi 8 SE supports QC3.0 fast charging, and can have about 16W charging power at 60% charge
Charging node diagram
Although the power is not very high, the actual charging speed of the Xiaomi 8 SE is very high, and the trickle charging speed is very short. It is full in 1 hour and 12 minutes. Nubia Z17S and One Plus 6, which are close to using the high current scheme, not only easily surpass Xiaomi 8, but even faster than Black Shark. Of course, a large part of the reason is that the battery is small. Black Shark has 4000mAh batteries, and Xiaomi 8 has 3400mAh batteries. In addition, the trickle charging time of Xiaomi 8 SE is very short, which together results in extremely fast charging. The points lost in the endurance are finally made up in the charging side.
summary
Xiaomi 8 SE reminds me inexplicably of Xiaomi 4C. its The outstanding selling points are photography and game performance, and there is no competition among a crowd of Snapdragon 660 models that are close to the price ：
Its appearance is absolutely recognizable, but different people will have different opinions on whether it looks good or not;
The adaptation of MIUI's fringe screen still needs time;
CPU performance is squeezed, and the improvement is concentrated on the game related GPUs;
Although taking photos is not as good as our flagship, it is difficult to meet rivals at the same price;
The battery life is slightly weak, but the charging is fast.
Then look at the price. You can buy the 4+64 version for 1799 yuan, which is only 200 more expensive than the same Xiaomi 6X. Compared with other Snapdragon 660 models in the price range of 1500 yuan, the difference of several hundred yuan can bring a significant improvement in game performance and photography, which is also worth it. However, although the 4G memory of MIUI is still enough for the time being, the author suggests that adding 200 can add 6G memory, and the service life/smooth life of this version will be longer.
Look at Liu Haiping, and then look at the actual performance, and quote the famous expert Wang Jingze:
Of course, in terms of cost performance, the Xiaomi 8 SE can't beat its own Xiaomi 8. On the basis of 1999 yuan, add 700 yuan to make Xiaomi 8. "Bite your teeth and open the sea and sky", that's what I said. It is a difficult choice between them, but in the final analysis, it seems that the power of speaking is not pinned on our reason, but on our wallet.
