As the flagship of 202 1, Xiaomi digital series shoulders the heavy responsibility of refreshing the performance of mobile phones and setting a new benchmark for the flagship. Xiaomi 1 1 is the first model of Qualcomm Snapdragon 888. Everyone must be as curious and expecting about its performance as I am.

Compared with Snapdragon 865 and Snapdragon 865 Plus, Qualcomm Snapdragon 888 manufactured by 5 nm process has undergone a series of upgrades in architecture. It uses Kryo 680 CPU with "1+3+4" core design, Cortex X 1 core with 2.84GHz as the super core, Cortex A78 with 2.4GHz as the three cores, and Cortex A55 with 1.8GHz as the performance core. In terms of graphics performance, Adreno 660 GPU is faster in rendering, optimized for the flexible design and higher performance requirements of game phones, and can run continuously and stably in a wider heating range.

In addition, in terms of AI processing capacity, Snapdragon 888 adopts the 6th generation Qualcomm AI engine including Hexagon 780, which can achieve 26 trillion operations per second (26TOPS). On the other two hardware with "iron triangle" performance, Xiaomi 1 1 is upgraded to "full blood version" LPDDR5 RAM and UFS 3. 1 ROM. Compared with ordinary LPDDR5, the frequency of "full blood version" LPDDR5 is upgraded to 3200MHz, and the transmission rate is increased to 6400Mbps.

From Snapdragon 865 to Snapdragon 888, from LPDDR5 to "full blood version" LPDDR5, from UFS 3.0 to UFS 3. 1, how much has the performance of Xiaomi 1 1 improved compared with the previous generation? We have tested Xiaomi 1 1 1 with 12GB memory and +256GB storage through a variety of testing software and games, and compared the results with Xiaomi 10 Pro.

In the evaluation of Ann Bunny, the score of Xiaomi 1 1 is 707574, including 198582 for CPU and 31/924 for GPU, which is 8 GB+compared with Xiaomi 10 Pro that we evaluated last year. In GeekBench 5. 1, which is specially designed for CPU performance testing, Xiaomi 1 1 single thread124 points, multi-thread 3622 points, in contrast, Xiaomi 10 Pro single thread 90/kloc-.

In the evaluation of Ann Bunny, 12GB+256GB Xiaomi 1 1 got 707574 points, and the comprehensive performance was obviously improved. The performance improvement of GPU is more prominent.

GeekBench 5. 1 single-threaded performance 1 124, multi-threaded 3622, Cortex X 1 super-core with strong performance.

It can be seen that Snapdragon 888 relies on Cortex X 1 core and 5nm process technology, which can effectively improve the single-thread processing ability, but the frequency and number of its cores have not changed, and the improvement of CPU multi-thread performance is relatively less obvious than that of single core. Adreno 660 GPU has made a qualitative leap in the graphics processing ability of mobile phones, bringing about nearly 50% performance improvement.

In the storage test of AndroBench, the continuous reading speed of Xiaomi 1 1 can reach 1837.6MB/s, and the continuous writing speed can also reach 769.98MB/s, which are 13.3% and 4.3% higher than Xiaomi 10 Pro respectively. Especially in the aspect of 4K random reading and writing, UFS 3. 1 is improved obviously, and the reading and writing speed reaches 263.28MB/s and 295.55MB/s respectively, which obviously reduces the game loading time and the App installation time.

In the storage test of AndroBench, the continuous reading speed of Xiaomi 1 1 can reach 1837.6MB/s, and the random reading and writing performance of 4K is improved, which obviously reduces the game loading time and App installation time.

In terms of actual game performance, we use Peace Elite and Genshin Impact to test, and use Perfdog to record the game frame rate. In Peace Elite with HDR high-definition quality and limited frame rate mode (full frame 60fps), the average frame rate of Xiaomi 1 1 reached 59.7fps, and the whole game process was very smooth, maintaining a continuous and stable output. In Genshin Impact, where the overall performance of mobile phones is tested, Xiaomi 1 1 is relatively stable at the highest picture quality. Controlling the game characters to run, slide and cast ordinary attacks is very smooth. Only in the face of siege and casting elements, there was an unexpected frame drop, but the game screen was not obviously stuck, and the average number of frames in the whole game remained at 55.9fps.

"Peace Elite" sets the picture to HDR high-definition quality and limited frame rate mode (full frame 60fps), and the average frame rate of Xiaomi 1 1 can reach 59.7fps.

Running the highest quality Genshin Impact game, the average frame number of Xiaomi 1 1 keeps at 55.9fps, and there is no obvious stagnation during the game.

In addition to its powerful performance, Qualcomm Snapdragon 888 also brings more comprehensive network connection to Xiaomi 1 1. The integrated Snapdragon X60 supports 5G sub-6GHz carrier aggregation and millimeter wave, and can provide commercial 5G network speed up to 7.5Gbps, supporting almost all major networks in the world. In the actual test, we tested its 5G rate near the 5G base station, and conducted several tests with SpeedTest, and got the best results. Xiaomi 1 1 has an actual downlink rate of 94 1Mbps and an uplink rate of 97.6Mbps. During the test, the Ping value is low, the jitter is small, and the connection is very stable. On the other hand, Xiaomi 1 1 also supports enhanced Wi-Fi 6. The bandwidth is upgraded from 80MHz to 160MHz, and the maximum throughput rate can reach 3.5Gbps, which is very stable in practical use, and online games and download applications are uninterrupted.

Xiaomi 1 1 The measured downlink rate near the base station is 94 1Mbps, and the uplink rate is 97.6Mbps, so the connection is relatively stable.

Different from the relatively stable design of Xiaomi 10 series, Xiaomi 1 1 has become thinner and more fashionable. Xiaomi 1 1 In addition to the "Lei Jun Signature Edition", it also provides two versions of AG frosted glass and plain leather in five colors. We got a smoky purple plain leather version, which looks very elegant and exquisite. The back cover of plain leather has excellent hand feeling and will not leave fingerprints after long-term use.

The plain leather back cover looks very advanced, feels comfortable and can effectively prevent fingerprints.

In detail, Xiaomi 1 1 is more exquisite than the previous Xiaomi mobile phone. The camera module adopts integrated glass CNC, which is beautiful and can better protect the lens. The curved waistline design makes the phone look thinner.

The front camera is located at the top left of the screen, and the micro-slit receiver is almost invisible, but it does not affect the call quality.

Having said that, I have to mention "the most expensive and best screen in the history of Xiaomi mobile phone". Xiaomi 1 1 is equipped with a 6.8 1 inch four-curved full-screen with a resolution of 3200 1400 and a pixel per inch of up to 5 15PPI, which brings a more delicate screen display effect. Thanks to the application of the new E4 luminescent material, the screen peak brightness of Xiaomi 1 1 is as high as 1500 nits, and it can also be displayed at 900 nits under strong light, which is higher than the common E3 luminescent material at present and lower in power consumption.

In terms of color, the screen of Xiaomi 1 1 supports 100 billion color display, and each screen will be calibrated before leaving the factory, thus ensuring accurate color reproduction of the screen and more realistic display effect, and even meeting the requirements of professional users for color display. I tested the color gamut of this screen with Konica Minolta CS-200 color luminance meter. In the adaptive mode, the screen of Xiaomi 1 1 covers 96.8% of the NTSC color gamut, and the color display is bright and bright. After switching to the bright mode covering 106.7% NTSC color gamut, the screen color will be further improved. As for users who like to be close to real colors, they can also switch to the primary color mode covering 72.9% NTSC color gamut.

In the adaptive mode, the screen of Xiaomi 1 1 covers 96.8% of the NTSC color gamut and has bright colors. In addition, it provides a bright mode and a primary color mode.

In order to give full play to the advantages of 2K resolution screen, Xiaomi 1 1 has added a brand-new AI master image quality engine, which supports functions such as super-resolution display enhancement, AI intelligent scene optimization, video enhancement, and dynamic picture compensation. In the display settings of Xiaomi 1 1, users can switch the display resolution (FHD+/WQHD+) and the screen refresh rate (120Hz/60Hz) according to the remaining power and their own needs, taking into account the picture quality and battery life. Super-resolution enhancement can carry out AI enhancement processing on 720p pictures or online videos, and get 1440p high-definition pictures and clear video pictures, and the quality improvement is quite obvious.

In addition to the improvement of visual effects, the screen cover of Xiaomi 1 1 also adopts the latest corning gorilla glass, Victus, which is the toughest corning gorilla glass at present, and has better anti-fall and scratch effects. The off-screen fingerprint module can not only quickly identify and unlock, but also measure the heart rate in Xiaomi Health APP, which has high accuracy in the actual test and can truly reflect the change of human heart rate.

Considering more and more mobile game users, Xiaomi 1 1 not only has strong performance, but also meets the needs of games and entertainment with the design from the inside out. 120Hz refresh rate and 480Hz touch sampling rate can provide clear and coherent game screen and arbitrary screen control, and perform well in games supporting high frame rate mode. Different from the general curved screen, Xiaomi 1 1 has a narrow curved area and small curvature, which takes into account the visual experience of users who like straight screen and curved screen, and can also effectively reduce the problems of color cast and misoperation. In addition, it also has two brand-new grip sensors built in to detect the grip state of the mobile phone. Combined with sensors such as gyroscope, it can realize intelligent error-proof judgment and error-proof operation in the grip area of palm.

Inside the mobile phone, Xiaomi 1 1 has built-in dual stereo speakers professionally tuned by Harman Kardon. In the actual experience, whether the game audio or songs are played outdoors, there is an obvious sense of space and excellent sound quality experience. I also felt the phenomenon that the back cover resonated when users gave feedback. When the volume is increased above 50%, the two-in-one linear speaker at the top of the fuselage will shake some air, making the back cover slightly shake. The use of protective shell can effectively alleviate this problem. The 4900mAh battery has a good endurance, and it can easily last for a whole day even if it is used a lot during the test.

The infrared remote control function is retained, and the sound hole of the two-in-one speaker is set on the top of the fuselage, and the logo of "Harman Kardon" is engraved.

Xiaomi 1 1 currently offers standard version (without charger) and set version (with 55W GaN charger). In our actual test, the 55W GaN charger charges Xiaomi 1 1, which is powered off. 10 can charge 29% of the electricity in one minute, and it can "return blood" in half an hour. Moreover, GaN charger is small in size, which can not only provide battery life for mobile phones, but also be used as power supply for some notebooks. I choose to use it instead of the original charger of MacBook Pro, and I only need one charger for my future travel and business trip.

In the test game, I also paid special attention to the fuselage temperature change of Xiaomi 1 1. Xiaomi 1 1 uses a lot of graphite, copper foil and thermal grease, and cooperates with a large-area VC steam chamber to sandwich the main board, thus forming a three-dimensional and efficient all-round heat dissipation system. Under the environment of room temperature 20, the maximum temperature of the fuselage of Xiaomi 1 1 light load game is 38.4 after half an hour, and it will be hot to the touch, compared with 44 after ten minutes of the original game.

Xiaomi 1 1 adopts a rear-mounted three-camera lens, namely/kloc-0.08 million pixel Samsung HMX main camera,/kloc-0.30 million pixel super wide-angle lens and 5 million pixel telephoto macro lens, which meets the needs of users to shoot the whole scene. We are already familiar with the main camera of Samsung HMX. It has11.33-inch photosensitive area, 7P lens, OIS optical image stabilization support, and can directly output ultra-high definition images.

The rear camera adopts a new arrangement, and the combination design of angel ring and rounded rectangle makes the fuselage look slim and not abrupt.

When using Ultra HD mode, I can clearly feel that the imaging speed of Xiaomi 1 1 is faster than that of the previous10.8 megapixel mobile phone, and the imaging is almost instantaneous from pressing the shutter, which is mainly due to the Spectra 580 CV-ISP (Computed Visual Image Signal Processor) integrated by Xiaolong 888, and the pixel throughput is increased to 2.7 billion pixels per second.

Under the daily lighting conditions, I use the default mode and ultra-high-definition mode to shoot high-rise buildings, and the main body of the building has a layered sense of light and shade changes, showing a good tolerance. In contrast, the default mode of Xiaomi 1 1 adopts the four-in-one pixel technology, and the picture is brighter by synthesizing 1.6μm, and the wall of the building still retains rich details; After switching to Ultra HD mode, the overall brightness of the picture decreases slightly, but the details are richer, which is convenient for later editing.

Ultra HD mode. The default mode can provide good tolerance. After switching to/kloc-0.08 million pixels ultra HD mode, you can see more prominent details by enlarging the same area (not more than/kloc-0.00%), which is convenient for later editing.

The technology of outsole and four-in-one pixel improves the photosensitivity of a single pixel, which makes Xiaomi 1 1 perform well in the night scene. As can be seen from the proofs, even if the default mode is adopted, Xiaomi 1 1 can fully show the bustling night scene of the shopping mall, the complex light sources can be well restored, and the noise of buildings and the night sky can be effectively suppressed, thus obtaining relatively pure night scene photos.

After switching to night mode, Xiaomi 1 1 will slightly improve the brightness of the picture, and the lights will become more dazzling, showing more details in the dark. Judging from the flagship mobile phone recently experienced, the difference between the default mode and the night scene mode is further narrowed, because after the shooting is completed, the flagship mobile phone has the spare capacity to optimize the photos later, and it will be more beautiful to view the photos after opening the album.

In the face of night scene shooting, the default mode (I) can better suppress noise, thus obtaining relatively pure night scene photos. After turning on the night scene mode (below), the brightness of the picture can be obviously improved, more dark details (at the red box) can be preserved, and the lighting is more brilliant.

In the face of big scenes such as magnificent buildings, Xiaomi's1113 megapixel ultra-wide-angle lens can come in handy. After the distortion correction function is turned on, the edge of the ultra-wide-angle picture taken by Xiaomi 1 1 has no obvious deformation, and large-scale buildings can be photographed completely. Xiaomi 1 1 In addition to the regular camera function, it also provides shooting modes such as front and back double scenes and post-editing functions including magic weather change. Different from before, Xiaomi 1 1 will automatically correct the brightness of the subject, the change of light and the color of the environment while "changing the weather", making the edited effect more realistic.

Super wide-angle mode (I) can shoot a grand scene with no obvious distortion at the edge of the picture. After the post-processing of "changing the sky with one key" (below), it can not only "change" the cold weather in Chongqing in winter, but also automatically correct the brightness, light change and environmental color of the building, making it look more beautiful and realistic.

If Qualcomm Snapdragon 888 is compared to the main ingredient of a big dish, then full blood LPDDR5, UFS 3. 1, 2K 4 curved surface screen, Harman Kardon speaker, VC liquid cooling system and10800000 pixel three shots are the side dishes and seasonings. After careful collocation, Xiaomi 1 1 and Colorful 20265438 are ripe.

As the first Qualcomm Snapdragon 888 model, we can also see some features of the flagship mobile phone equipped with this platform in the first half of 2002/KLOC-0. The enhanced version of LPDDR5 and UFS 3. 1 will be their standard configuration. The screen with high refresh rate, high resolution and high touch sampling rate can give full play to the advantages of Snapdragon graphics processing, supplemented by large-capacity battery, GaN fast charging and liquid cooling system to meet the needs of gamers.
