Let's welcome the annual dark horse, flagship shredder, popular candidate of Shenu, and the real game chip Tianji 8100!
On the evening of March 17, in the Luweibing Square and the Rice Noodle Spring Festival Gala, the "Armored Wuling" (K50) series was officially released. At 2399 yuan, the Redmi K50 with 2K screen+Tianji 8100+5500mAh battery is undoubtedly the MVP of the whole show.
Now let's take a look at Tianji 8100, the love letter sent by MediaTek to Jiquan.
PS： [No dinner in this issue] Identify the author of the public account“ Love to play computer games The handsome boys of ", the content of chili sauce certification is not proper;
PS2： For the convenience of viewing, the evaluation of K50 and K50 Pro has a lot of mutual references.
Redmi K50 specification reread, The key word is "Tianji 8100, 2K screen, from 2399 yuan" 。 K50 Pro has the same appearance, 8.48mm, 201g weight. 6.67 "120Hz Samsung E4 2K AMOLED flexible straight screen, 3200x1440. Front 2000W, 4800W IMX582+OIS, 800W ultra wide angle S5K4H7+200W micro distance, 5500mAh battery+67W fast charge. 8+128 version 2399 yuan, 8+256 version 2599 yuan, 12+256 version 2799 yuan.
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 67W fast charger is the ancestral MDY-12-EF, which has been in use since K40 game enhancement and Redmi Note 10 Pro.
Like the previous generation operation, K50 and K50 Pro are the same appearance mold, which is exactly the same, including 3D, weight and color matching.
Ink Feather K50 Pro ↑
Dark Edition K50 ↑
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 of ink feather color matching. At first glance, it looks like broken glass, and when you look at the grain, it changes a lot. I like it. The Youmang (green) color matching is AG glass, simple and clean, and never wrong AG.
Fingerprint&system&external amplifier&vibration motor
Redmi K50/K50 Pro are both tactile and FPC fingerprints.
The ancestral side fingerprint, which we said in K40 evaluation, 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: 2K+120Hz+straight screen
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 recorded beliefs are less than K50 Pro.
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. DC mode is available, but 60Hz is locked. It is officially announced that there will be 120Hz DC in the future.
The Redmi K50 Pro has 492/489/483/486 nit of brightness at four corners under the condition of 477 nit of maximum brightness in the center, which is slightly worse than its brother's uniformity. In fact, it is OK on the whole. The highest brightness is stronger than Xiaomi 11 and slightly weaker than Xiaomi 11 Ultra, which is sufficient for daily use.
The gamma value under different display modes is very accurate, and the color accuracy of the three display modes is slightly weaker than that of Big Brother, However, except for the bright mode, the color accuracy of the other modes can still win the competition of Zhenwo, iQOO and Huawei flagship.
This is the only 2K straight screen (the other one is on the real GT2 Pro). Apart from the lack 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. Sir, the times are changing.
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 camera hardware is to add OIS:
2000W，IMX596，0.8 μ m. F2.24 Main camera (the same specification as Xiaomi's ancestral K3T2);
4800W，IMX582，0.8 μ m，1/2''，F1.79，OIS；
Ultra wide angle 800W, S5K4H7, 1.12 μ m，1/4''，F2.2； (Same as Redmi Note 11 Pro+)
200W macro, GC02M1, 1.75 μ m，1/5''，F2.4。
This camera is a love letter for the code scanning party. The 4800W is very sweet. The IMX582 has been eaten through for a long time. The performance consumption is low, still equivalent to 0.8 μ M double digital cutting, OIS optical anti shake, more stable code scanning To enhance the scanning experience and the recognition rate of long-distance two-dimensional codes.
The K50's night scene completion rate is far higher than that of the K40 Pro without OIS. The completion rate is good, and the imaging speed is fast. The ultra wide angle still has no automatic night scene, and the automatic HDR is also very inactive.
Because of the epidemic situation and time, it is only in time Briefly 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
As an old CMOS, the algorithm of the IMX582 is very mature. The dynamic range of the K50 is larger than that of its big brother no matter day or night. The dark details are more abundant, the white balance and light metering are relatively normal, and the highlight suppression is stronger than many phones of other brands. But after all, it is MediaTek, and it is a new SoC. In algorithm debugging, it is still the same as the K40 of Snapdragon 888 There is a gap in Pro. Even if there is OIS in the K50, the night view is still weak, mainly due to the gap in the dynamic range of the dark part.
Performance: riding face output for Qualcomm
Redmi K50 code 22041211AC, Tianji 8100 code MT6895. MediaTek positioned Tianji 8100 and Tianji 8000 as light flagship, but The actual CPU and GPU output makes the Tianji 8100 not so close to the "light flagship".
The TSMC 5nm process is used. The CPU is 4x2.85GHz A78+4x2.0GHz A55, 512KB L2 cache with large core, and 4MB L3 cache. From the perspective of K50 CPU scheduling, it is more like a 1+3+4 structure.
The GPU is Mali-G610 MC6, and its frequency cannot be found for the time being, but its frequency will not be lower than 850MHz from the gap between its performance/scale and Tianji 9000. Mali-G710 starts with 7 cores, ends with 16 cores, and G610 with 6 or less cores. The core size of the G610/G710 GPU has doubled, which can be generally understood as the previous generation MC12. It is already a large size.
The Tianji 8100 supports the current maximum 6400Mbps LPDDR5 memory, 3-way 14bit ISP, dual 3200W+1600W cameras, Wi Fi 6E and Bluetooth 5.3 support (but does not have the 160MHz bandwidth of Tianji 9000). It even has the MediaTek M80 baseband of the same model as Tianji 9000, but the peak speed is "only" 4.7Gbps. Tianji 9000 is 7Gbps, and it also lacks the support of dual card dual pass. Of course, few manufacturers now engage in dual card and dual pass.
The main features of Tianji 8100 and Tianji 8000 are frequency and screen support, respectively Lu Weibing said that because Redmi needs 2K screens, Tianji 8100 will appear.
The performance of K50 Tianji 8100 can be summarized as Single core CPU slightly stronger than Snapdragon 865, multi-core CPU stronger than Snapdragon 888/Snapdragon 8 Gen 1, and close to GPU of Snapdragon 888. The read-write performance of flash memory is second only to Tianji 9000, which is second to Qualcomm's family.
Its CPU multi-core has the strongest energy consumption ratio in the Android camp (the single core energy efficiency record is still in the hands of Snapdragon 865), and its GPU energy consumption ratio is only second to Tianji 9000, and also surpasses the Qualcomm family (including Snapdragon 865).
In practice, the Redmi K50 does not need a game mode to actively maximize the frequency of application startup and high load (this is normal SoC behavior). Four 2.85GHz large cores are even more active than small cores, which makes it The smoothness of application installation and daily use is close to that of Tianji 9000 。 However, the resolution of K50 has also been reduced in the original god. The Peace Elite can not even open HDR by default. Fortunately, 720P can be unlocked manually.
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.
Normal mode, static, MIX 2 single baking CPU, single baking GPU MADD
Performance mode, static, MIX 2 single baking CPU, single baking GPU MADD
K50 and K50 Pro are highly consistent hardware, which is very suitable for comparing platform power consumption. Also force on 2K 120Hz+flight mode minimum brightness, The basic power consumption of Tianji 8100 is 0.73W, slightly lower than the 0.78W of Tianji 9000.
28.9 degrees, humidity 75%, K50 in normal mode, Tianji 8100 MIX2 single bake CPU unexpectedly reduced 2GHz A55 to 1.4GHz in just 10 seconds, but the big core still has full power, which is really a long time to see. In about 100 seconds, the large core also dropped from 2.8GHz to 2.35Hz and can be maintained for a long time. At this time, the fuselage is slightly warm (it is still warm when the room temperature is close to 29 degrees), The default temperature control is conservative.
The GPU is a classic energy-saving unit, with a room temperature of 28.9 ℃, GPU Output and power consumption are in line. Even in the performance mode, the power consumption of the whole machine has been maintained at about 3.9W (3.7W in the normal mode), which has not been seen on the flagship SoC for centuries. The fuselage is also only partially warm. Fage Saigao! TSMC Saigao!
CpuFloat shows that the core temperature is also soaring as fast as Tianji 9000, but the actual fuselage is only partially warm. It is not sure whether it is a similar problem of large buffer heat accumulation? Or the problem of platform software detection? It needs further testing.
In terms of temperature control, K50 is more open than K50 Pro, although the surface temperature line is also 48 degrees. However, the room temperature is 27.5 ℃, the screen brightness is 200 nit, and the humidity is 77%. The Redmi K50 was tested under 3DMark Wild Life Unlimited pressure for 30 minutes, and the stability is 99.2%. The highest temperature is also at the front, 47.8 ℃.
Wild Life U stress test in normal mode and performance mode, and Wild Life Extreme stress test in performance mode ↑
Terrible stability, On the one hand, it depends on the terrible energy consumption ratio of Tianji 8100, and on the other hand, its GPU performance is just good.
If the test is adjusted to the 3DMark Wild Life Extreme test with higher pressure (also the test of running 20 rounds in a row), the stability of the K50 will be only 65.7%, and the fluctuation between different cycles can be seen, which is different from the performance of the Xiaolong platform that can not go down when it comes down. This shows that the extreme power consumption of this GPU is just like this. As long as the ambient temperature is lower, its stability performance can be significantly improved.
If the 20 minute Elite of Peace HDR+limited frames+anti aliasing, 27.5 ℃ room temperature+200nit brightness, the highest temperature of the Redmi K50 is 42.3 ℃, which also appears on the front, and the temperature is slightly higher than that of the K50 Pro. On the one hand, the GPU is slightly weaker than Tianji 9000, and on the other hand, K50 scheduling and temperature control are more open.
The CPU and GPU output of Tianji 8100, combined with the huge gap in energy consumption ratio, It is simply the riding output of MediaTek to Qualcomm, which is extremely harmful and insulting.
Endurance and charging
The Redmi K50 is a 2K screen+Tianji 8100+5500mAh single cell. After 30 minutes of "Peace Elite" (HDR high-definition+limit 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 testing, the remaining power is 79%. 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 Even the 2K screen has set a new record for endurance 。 The iQOO Z5 defeated the LCD+5000mAh battery+Snapdragon 778G, and the iPhone 13 Pro Max defeated the true LTPO+A15. Given a LCD 1080P screen or LTPO version, Tianji 8100 can take off with endurance.
This story tells us that any screen is fake, which is not as direct as changing to a more power saving SoC. In addition, the Tianji 8000 is basically the reduced frequency version of the Tianji 8100, and its endurance is expected to be more terrible.
67W fast charge of Redmi K50, peak 58W, lasting for 4 minutes; 46W for 10 minutes; Then 37W and 30W; The curve drops after 27 minutes, it becomes 5V charging after 41 minutes, and it is disconnected after 55 minutes.
The Redmi K50 is charged to 19% in 5 minutes, 35% in 10 minutes, 50% in 15 minutes, and 85% in half an hour. It takes 51 minutes to fully charge, and it will be disconnected after 4 minutes. The time difference between UI full and actual full is only 4 minutes, and the phase power difference is only 1% to 2%.
K50 Even if it is 5500mAh+67W, it is still faster than the 4360mAh+66W Huawei P50 Pro, Even the speed of the first 15 minutes is not much slower than the 65W of the real GT2 Pro. This 67W is enough.
Reasonably, in my opinion, 5550Ah+67W is more balanced than 5000mAh+120W. If you add a 50W wireless charger, this configuration will not fall behind in five years.
summary
The false flagship of Android in 2022: Snapdragon 8 Gen 1
What you think is the flagship of Android in 2022: Tianji 9000
The actual flagship of Android in 2022: Tianji 8100
In 2022, you will finally get the flagship of Android: Snapdragon 870
False game phone: Snapdragon 8 Gen 1
Real game phone: Tianji 8100
The performance of Tianji 8100 is strong and balanced, which makes people sigh that MediaTek has caught up with the best Meizu, but Meizu has not caught up with the best MediaTek.
Coupled with Redmi's more sophisticated knife technique, At 2399 yuan, there is Samsung E4 2K straight screen+Tianji 8100+5500mAh battery, and you can also get infrared, IP53 and 67W fast charge. This is the top equipped bicycle 。 The disadvantage is that different people have different opinions on the appearance, the texture of the plastic middle frame is ordinary, and there is no wireless charging. But these are nitpicking in front of 2399.
One year after Xiaomi 11 used the 2K screen, Redmi came to the 2K screen. In addition to the process, camera and wireless charging, the performance output, endurance and wired charging have all achieved comprehensive surpasses (dry turning friends!)
The 8+128 version of the Redmi K50 is 2399 yuan, the 8+256 version is 2599 yuan, and the 12+256 version is 2799 yuan. Now the official store's Xiaomi 11 will cost 2969 yuan, and the Snapdragon 870's K40S will cost 1999 yuan (regardless of the 6G memory version, WeChat can eat up memory with one app). The price difference of 400 between K40S and 2K screens, stronger SoC and 1000 mAh batteries is not bad. As long as you don't wait for the 400 yuan emergency, it is recommended to bite the bullet and open the sea.
Everyone scolded iPhone SE 3 like this:
3499 Despicable and shameless cooks put industrial waste in the backward era
2799 Fruit Company launched an ingenious retro design
2399 The famous mobile phone manufacturer released a new flagship with strong performance
In 1999, the great technology company that inherited the will of Mr. Jobs created a modern machine for us
But with 2K screen, Tianji 8100 and 5500mAh batteries, Even if it is 2399, I would also like to call the Redmi K50 the modern machine king! At the moment when the price was announced at the press conference, the K50 seemed to coincide with the first generation of Xiaomi. My wallet was filled with tears, as were the users who had just bought the flagship of Snapdragon 8 Gen 1.
