On the evening of March 17, Redmi released the Redmi K50 Pro of Tianji 9000, the K50 of Tianji 8100 and the K40S of Snapdragon 870. K50 and K50 Pro are unprepared With the 2K screen and MediaTek Tianji package, the peripheral configuration is stronger, but the price is reduced instead 。
Although it is not a nominal debut, the Redmi K50 Pro is a "physical debut". Now let's see how Tianji 9000, who has been waiting for a long time for a long time, performs
PS： For the convenience of viewing, the evaluation of K50 and K50 Pro There are a lot of cross references.
Redmi K50 Pro specification is simply repeated, and the key words are "Tianji 9000, 2K screen, from 2999 yuan". 8.48mm thick, 201g weight, 6.67 inch 120Hz Samsung E4 2K AMOLED flexible straight screen, 3200x1440, gorilla Victus glass. Front 2000W IMX596, main camera 100 million pixels HM2+OIS, 800W ultra wide angle S5K4H7+200W macro, 5000mAh+120W fast charge. 8+128 version 2999 yuan, 8+256 version 3299 yuan, 12+256 version 3599 yuan, 12+512 version 3999 yuan
Because K50 and K50 Pro use exactly the same mold, many components, including batteries, can be interchanged except that the main camera and screen touch are not common. However, the 5000mAh battery of the Redmi K50 Pro is designed for 120W fast charging, Although the physical size is the same as 5500mAh of K50, the capacity density and fast charging durability of both are different, and it is not recommended that users with hands-on ability and financial resources replace them by themselves However, I hope Redmi can provide a 5500mAh battery+67W fast charging version for K50 Pro.
Appearance packaging
The packaging of K50 and K50 Pro is different only in charging specifications and corner marks. There are also blind boxes of the mascot Kino sold this year ↑
The 120W fast charging head of Redmi K50 Pro is also MDY-12-ED. The latter is a real heirloom, and has been used since the Xiaomi 10 Ultra, the first 120W fast charging head in 2020. Cook and OPPO have to make up three thirds of its leading specifications and environmentally friendly molds.

Dark Edition K50 ↑
As in the previous generation, K50 and K50 Pro are the same appearance mold, which is really the same , including 3D, weight, and color matching. So the appearance of our two mobile phones is "copy and paste". If you have seen the K50 evaluation, you can skip this part.
From top to bottom are K50 E-sports version, K40 Pro, K50 Pro and K50 ↑
Interface layout, Seriously condemn any behavior of "putting the microphone next to the SIM card slot" . The previous generation put the microphone beside the speaker, but this generation put it back beside the SIM card slot. According to incomplete statistics, the microphones of hundreds of millions of mobile phones are injured by SIM card needles every year.

The chin control of K50/K50 Pro is better than that of K40, and the body width and height are smaller. In order to add 500mAh battery and cooling configuration, this generation of The thickness is bigger, and the radian of the back cover is not as comfortable as the previous generation.
Reasonably, the appearance design of K50/K50 Pro is inferior to that of K40 series. The first is the harmony of the camera matrix, the second is the side radian, and the third is the color details (the black K40 is actually a gray middle box, and the K50 is pure black, which suffers from the texture).
The K50/K50 Pro is the same as the previous generation. The edges of the plastic middle frame and the upper and lower bottoms have been polished. This design is very "eat color" and has little impact on the dark color model. The light color model will form an obvious blinking effect, which is difficult to create a sense of quality.
However, the ink feather color matching (nano microcrystalline+photolithography) of K50 series is more elegant than the previous generation's ink feather color matching. At first glance, it looks like broken glass, and when you look closely, the lines are ever-changing, I like it。 The Youmang (green) color matching is AG glass, simple and clean, and never wrong AG.
Fingerprint&system&external amplifier&vibration motor
The ancestral side fingerprint (sink top) of Redmi K50 Pro was mentioned in K40 evaluation, and we still maintain the same conclusion. Unless it is a wide area 3D ultrasonic fingerprint, the actual experience of the fingerprint under the screen is not as good as that on the side of the entity (except Sony), Physical fingerprint is still an insurmountable peak 。
The MIUI 13 system will not be repeated. It can be understood as the MIUI 12.5 with simplified animation, slightly lightweight, larger font and more intensive typesetting. Most importantly, K50/K50 Pro Although it is Fage platform, it has Google framework, and CDM is L1.
Both the external amplifier and the motor are at the same price and normal level. They are not brilliant, but they are not a drag.
Screen: almost all except LPTO
6.67 inch 120Hz 2K AMOLED flexible straight screen, made of Samsung E4 material, has no visual angle problem of E5 screen microlens. 3200x1440526ppi, gorilla Victus, 480Hz touch sampling. DisplayMate A+16 more recorded beliefs than K50.
The brightness of K50/K50 Pro is very close to that of the naked eye (after all, it is the same screen), and the core difference is color calibration.
The Redmi K50 Pro has a maximum brightness of 473 nits in the center, and a four corner brightness of 486/483/482/482. The uniformity performance is good. The highest brightness is stronger than Xiaomi 11 and slightly weaker than Xiaomi 11 Ultra, which is sufficient for daily use.
The gamma values under different display modes are very accurate (directly affecting the contrast control), and the color accuracy performance of the three display modes is better than that of Xiaomi 12 Pro (dry turning Xiaomi!). DC mode is available, but 60Hz is locked. It is officially announced that there will be 120Hz DC in the future, waiting for good news. As long as it is not DC, it is worth waiting more.
Apart from the absence of LTPO, this screen has no regrets.
Remember "No 2K, no A screen"?
Can you remember the world before the 1080P A screen dominated? The LCD screen arranged in 1080P RGB is the best dessert. It is said that the 2K RGB LCD is in the wrong direction. Then came the 1080P A screen. At that time, people shouted the slogan "No 2K, no A screen", which was the consensus of mankind in the last century. But now?
Ordinary people in 2022 will find the 1080P A screen every time they look at the screen carefully, The fineness is not as high as the 2013 antique in the drawer. The low-frequency PWM mobile phone has been used for a long time, and his eyes are sore. He still thinks he is old.
Two years ago, Samsung's own flagship could not achieve 2K 120Hz. But now we don't need to go to Little Yellow Croaker to find the foreign garbage flagship and PDD. The new machine has a 2K 120Hz straight screen of 2399 yuan.
Earthlings always like to compromise.
For example, you said that the LCD contrast is not good. If you want to change to 1080P A screen, you must not allow it.
But if you want Zhou Dongyu's 1080P A screen, they will adjust it and are willing to use the ordinary 1080P A screen.

The core upgrade of Redmi K50 Pro camera hardware is to add OIS:
2000W, IMX596, 0.8 μ m, F2.24 main camera (the same specification as Xiaomi's ancestral K3T2);
10800W, S5KHM2, 0.7 μ m, 9in1 into 2.1 μ m, 1/1.52 "", F1.9, OIS;
Ultra wide angle 800W, S5K4H7，1.12μm，1/4''，F2.2；
200W macro, GC02M1，1.75μm，1/5''，F2.4；
Reasonably, the size of HM2 is larger than that of the IMX766 running all over the street. With OIS, the Redmi K50 Pro should be regarded as the flagship of entry. In addition, the ISP of Tianji 9000 is also very strong, but it is generally acknowledged that it is not easy to tune.
Redmi K50 Pro has a good photo taking experience, and multi frame synthesis is not very active, The main camera has automatic night view, but not super wide angle . Actual The rate of night scene is lower than K50, higher than Xiaomi 11 Ultra.
Because of the epidemic situation and time, it is only too late to simply compare K50/K50 Pro, K40 Pro and Xiaomi 11 Ultra:
Main panoramic contrast
Main camera contrast, central amplification
Main camera contrast 2
Main camera contrast 2, central amplification
Main camera contrast 2, zoom in on the right side of the center
Ultra wide angle contrast 1
Ultra wide angle contrast 1, central amplification
Ultra wide angle contrast 1, left edge enlarged
Ultra wide angle contrast 2
Ultra wide angle contrast 2, right central magnification
Redmi K50 Pro with current firmware, There is a tendency to press the dark part, the white balance is magenta, and the anti glare ability of the lens is average. The dark details of the night scene will be abandoned, but the highlight suppression is good, and the discrimination is also good.
Ultra wide angle is very suitable for comparing the ISP of Qualcomm and MediaTek. From the different results of K40 Pro (Snapdragon 888), K50 (Tianji 8100), and K50 Pro (Tianji 9000), we can see that Qualcomm's algorithm is better. However, it should be noted that none of them has the automatic night view function. At the actual imaging speed, they may not even trigger multi frame synthesis. This scene may be the most basic and realistic single frame output.
Performance and Games
Re read the specifications of Tianji 9000, MT6983， TSMC 4nm, 3.05G X2 (1M L2)+3x2.85G A710 (512K L2)+4x1.8G A510 (256K L2), 8M L3 and 6M SLC cache, the first 7500Mbps LPDDR5x memory support.
The GPU is Mali-G710 MC10, and the frequency is 848MHz. Because of the scale adjustment of this generation, MC10 can be generally understood as the previous MC20, and the scale is also very considerable.
The "enemy in life" Snapdragon 8 Gen 1 is Samsung 4nm, 3G X2+2.5G A710, and L2 cache on both sides is consistent. The L2 cache of Qualcomm A510 small core is unknown, and it uses the core 2+2 structure design with less area, 6M L3+4M SLC, 6400Mbps LPDDR5 memory.
The Tianji 9000 has a higher frequency of super cores and large cores, higher L3 and SLC caches, and higher memory specifications (although there is no mass production machine using LPDDR5x memory), but the biggest difference may be the process difference between TSMC and Samsung.
The performance tuning of the Redmi K50 Pro is obviously conservative, but it is Tianji 9000 after all. Except that the GPU is slightly weaker than the Snapdragon 8 Gen 1 (especially in the 3D Mark, known as Qualcomm Mark), other parts are the strongest in Android. The most unexpected is the flash memory read and write performance. Both sequential and random read and write are Android ceilings.
Because of the interference of the white list of running points, you can cooperate with GeekBench 4 and RAR test to watch (the latter is definitely not a white list). They are closer to the peak performance of daily use. The GPUs of Tianji 9000 and Snapdragon 8 Gen 1 are indeed better than all Android SoCs in the past. It will be more obvious when running GPU tests together. Tianji 9000 always runs a few steps ahead of others and then enjoys the cool.
Performance mode RAR frequency, normal mode daily peak frequency, 3DMark stability test ↑
In the current version of firmware, the maximum frequency of normal use of the Redmi K50 Pro is limited to a very conservative 2.3G+2.45G+1.4G, The 3.05G+2.85G+1.8G fire can be fully opened only when the performance mode is turned on when the application and high load are turned on. It is obvious that manufacturers are scared by Snapdragon 8 Gen 1.
As long as these "3A masterpieces" on Taobao are not opened, the fluency of the two modes is not very different. But for users who are accustomed to flagship products like Snapdragon 865/870, the fluency of both can be perceived. Personally Redmi can be more relaxed.
It was mentioned in the press conference that the original spirit can stabilize 59 frames in one hour, and the maximum temperature is 46 degrees. I don't know what the official conditions are. And we In the original God test, the average frame rate is 54.8 frames in 20 minutes, which is relatively stable overall.
However, pop all the options and count the sawtooth through the screenshots, Redmi K50 Pro Only 576P In fact, Tianji 9000 can be 720p in the original god. Temporary package name change, game mode switch and other methods cannot be adjusted temporarily. In addition, Glory of the King will be reduced to 900P, but Peace Elite will be 720P 。
In the game mode, the Redmi K50 Pro will lock the CPU more obviously. I hope the official can open the full fire switch. Even if the entrance is a little deeper, it can still prevent small white users from mistakenly opening and then spraying. Anyway, users who need image quality or hold a heat dissipation clip should be left with a full fire.
Heating and power consumption
In terms of heating, Redmi sets The surface temperature line may be 48 degrees 27.5 ℃ room temperature, 200nit screen brightness, 77% humidity, Redmi K50 Pro pressure test in 3DMark Wild Life for 30 minutes, 65.1% stability, the highest temperature in the front, 48 ℃. The performance is obviously better than that of Snapdragon 8 Gen 1 After all, in this environment, many Snapdragon 8 Gen 1 could not persist in the test.
For the 20 minute Elite of Peace HDR+limited frames+anti aliasing, 27.5 ℃ room temperature+200nit brightness, the maximum temperature of the Redmi K50 Pro is 40 ℃, which also appears on the front. Two years ago, the large-scale games in front of this generation of GPUs were just a drizzle.
In GPUGFLOPS, Redmi K50 Pro forces 2K 120Hz+flight mode+minimum brightness Static power consumption is about 0.78W (All GPUGFLOPS screenshots below are in this setting), the static power consumption of 1080P 60Hz mode is about 0.57W.
The above are the results of single thread locking of super core, big core and small core. It seems that GPUGFLOPS cannot lock it at all (in performance mode, software power consumption test results are for reference only)
The above results are CPU MIX 2 single baking, GPU MADD+ADD single baking, and GPU MADD single baking. At room temperature of 27, GPU fire can only be fully opened for 3 or 4 minutes regardless of performance mode.
In the AndSPEC test, the effect is as shown in the figure. The power consumption unit is disordered, but the result is not affected. Interested users can refer to it.
The mass production version of Tianji 9000 is far better than the Snapdragon 8 Gen 1 and the Snapdragon 888 in terms of heat generation, but its energy efficiency is not as strong as that of engineering machines. even if it is TSMC 4nm can not withstand the full power of 6M L3+4M SLC "PC level cache" . There is also some blame for the new armv9 instruction set and the X-2 architecture.
During frequency and temperature monitoring, it can also be found that the core temperature of GPUGFLOPS and other baking machine tools rises rapidly. It reminds us of AMD using TSMC's 7nm process. Too advanced manufacturing process, too small Die size, The problem of heat accumulation makes wind and cold water cool people's life, etc 。
The huge heating of circuit structures such as buffer can only be suppressed by PC active cooling. When the mobile SoC is close to the scale, it is really unrealistic to press the small copper foil and small VC soaking plate of the mobile phone. Mobile phones, as mobile products, are not suitable for high power SoCs at all. Even if the performance is several times better than that of today, it is useless, Snapdragon 8 Gen 1 and Tianji 8100 are the best opposite examples.
Endurance and charging
Redmi K50 Pro is a 2K screen+Tianji 9000+5000mAh single cell. After 30 minutes of "Peace Elite" (HDR high-definition+limited frames+anti aliasing), 30 minutes of Youku 1080P video playback, 30 minutes of microblog short video, 30 minutes of Wi Fi and 5G surfing, a total of 2.5 hours of endurance test, the remaining power is 74%. Note: Station B consumes 40% more power than Youku due to unknown reasons. Except for the two new machines of MediaTek, all other videos are played at station B.
Redmi K50 Pro The endurance has exceeded many 1080P screen models of Snapdragon 870 and Tianji 1200 , excellent performance. It is better than LTPO 2.0's One Plus 10 Pro. This story tells us that no matter how power is saved by LTPO, it is better to change to a more power saving SoC.
The Redmi K50 Pro is the same type of surging P1 self-developed charging chip as the Xiaomi 12 Pro. Its core advantage lies in the 5000mAh single cell 120W fast charging, taking into account the capacity and speed.
120W for Redmi K50 Pro, with a peak value of 100.6W, lasting for nearly 4 minutes; Then it fluctuates, and its fluctuation duration is directly related to curve and ambient temperature; 73W for about 9 minutes for 2 minutes; 11:30, 58W for 3 minutes; 46W for 2 minutes; 19 minutes and 40 seconds. The time of UI filling on Redmi K50 Pro is very close to the actual filling time.
The Redmi K50 Pro is charged to 34% in 5 minutes, 63% in 10 minutes, 86% in 15 minutes, and full in 20 minutes. When the battery capacity is larger than that of Xiaomi 12 Pro and iQOO 9 Pro, the speed is faster, which is close to 120W of game phone level.
The charging power curve at room temperature of 28 ℃, and the ambient temperature significantly affects the output of the middle section ↑ (yes, Shenzhen has entered summer)
But Redmi K50 Pro The charging speed is very sensitive to the cooling environment The fuselage is also too hot when charging. We had a room temperature of 24 degrees, and only 20 minutes of charging time could be achieved with the mobile phone standing on its side. Many multimedia charging speeds exceed 27 minutes, which may be due to the slightly higher ambient temperature.
Conclusion: This is not much better than the Snapdragon 8 Gen 1?
The 5799 yuan Tianji 9000 was delayed, but the 2999 yuan Tianji 9000 came. lose at sunrise and gain at sunset. Although not as exaggerated as the energy consumption ratio of MediaTek engineering machines Tianji 9000 is much better than the "broken chip" of Snapdragon 8 Gen 1. It is the real flagship SoC of 2022.
8+128 version of Redmi K50 Pro is 2999 yuan, 8+256 version is 3299 yuan, 12+256 version is 3599 yuan, and 12+512 version is 3999 yuan. At 2999 yuan, you can get Tianji 9000+2K screen+120W fast charging+HM2 with OIS, even IP53 and infrared. All Snapdragon 8 Gen 1 models should be ashamed.
Redmi didn't stack cameras and charge wirelessly, which is the face of all high-end flagship companies. If it is not for the pursuit of extreme photography, the Redmi K50 Pro is the best choice at the same price today, which may not be one of them. Before 618, only its younger brother could threaten the Redmi K50 Pro.
