Now, the Redmi K50 series is finally officially born. We Kuai Technology also got two versions of Redmi K50 and Redmi K50 Pro ahead of time, equipped with MediaTek Dimensity 8100 and Dimensity 9000, respectively.
Here, let’s experience the standard version of the Redmi K50. The core configuration of the Redmi K50 is a three-piece performance set consisting of Dimensity 8100 + full-blooded version of LPDDR5 memory + upgraded UFS 3.1 high-speed flash memory. Benchmark Snapdragon 888/888+.
The Dimensity 8100 is positioned as the second flagship. It adopts TSMC’s 5nm manufacturing process, integrates an eight-core A78+A55 CPU, the highest frequency reaches 2.85GHz, integrates a six-core Mali-G610 GPU, and integrates a new APU AI unit, which is higher than that of the Dimensity 1200. %, integrated 5G baseband, the maximum download speed is 4.7Gbps.
The Dimensity 9000 and the Snapdragon 8 compete on the flagship platform; the performance is the same and even surpasses multi-core CPU. The energy efficiency is a lot ahead.
It can be said that MediaTek has been “suffering” for so many years and finally launched a chip that can surpass Qualcomm’s Snapdragon, allowing the market to have more choices. This is also the “healthy competition” situation that users expect.
The mission of the Dimensity 8100 is to bring down the Snapdragon 888/888+, whether it is performance or energy efficiency, as well as terminal price. As for whether it can be done, we will see below.
In addition to performance, Redmi is also committed to popularizing 2K screens. The Redmi K50 uses the same Samsung AMOLED flexible straight-edge screen as the K50 Pro.
It has a resolution of 3200×1400, a refresh rate of 120Hz, and a PPI of 526. It also has an ambient color temperature, DC anti-flicker dimming, 16,000-level automatic brightness adjustment, and supports HDR10+, Dolby Vision. Factory primary color screens, etc., are completely flagship-level on the market.
In addition, the Redmi K50 also has a 5500mAh large battery and 67W fast charging, and the charging and battery life are completely free from the “burden” of 2K high brushing.
Next, let’s take a look at the specific performance of this Redmi K50 equipped with Dimensity 8100. The following picture shows the parameter information:
Design & Appearance
The overall color of the outer box is white, which is very simple. There is only a golden K50 on the front, and 67W and 2K are printed on the side, indicating that it supports 67W fast charging, and the screen adopts a 2K resolution.
The K50 we received has a silver trace color scheme, a double-sided glass body, a frosted surface, and a metal texture reflective; combined with the distinctive square and round collision design, it looks full of high-end feeling.
The front of the Redmi K50 uses a 6.67-inch Samsung AMOLED flexible straight screen with a resolution of 3200×1400, a refresh rate of 120Hz, and supports HDR10+ and Dolby Vision.
This is also the first time that the Redmi series adopts a 2K flagship straight screen, which can improve the display effect and optimize the false edge touch.
Up to 16,000 levels of automatic brightness adjustment, plus ambient color temperature sensing, allowing users to watch the screen outdoors and indoors very comfortably.
This screen also supports DC anti-flicker dimming; users are not afraid of hurting their eyes when using it in a low-brightness environment.
The Sony IMX596 sensor is used in the front digging area, and the 20 Megapixels can bring a clearer portrait effect.
At first glance, the author thought that the K50 uses a narrow frame with the same four sides. After careful observation, I found that the top and bottom are slightly wider, but the overall visual effect is very good, with a strong sense of unity and immersion.
For local details of the camera, the main camera lens used by the K50 is a 48-megapixel Sony IMX582 sensor, combined with an 8-megapixel 119° wide-angle lens and a 2-megapixel macro lens to form a three-camera solution.
At the same time, Redmi also used OIS optical image stabilization for the K50 for the first time, which is not available in many flagship phones.
In partial details of the top and bottom and the conventional USB-C interface and SIM card slot, the K50 also supports Dolby Atmos stereo dual speakers and infrared.
The physical buttons of the K50 are on the right side of the fuselage, with the volume up and down buttons on the top and the power button that supports fingerprint recognition on the bottom.
The whole family bucket in the package comes with a SIM card needle, charger, data cable, manual and water sleeve.
Hardware & Performance
The MediaTek Dimensity 8100 powered by the Redmi K50 adopts TSMC’s 5nm manufacturing process. The processor is an 8-core processor consisting of 4 A78 cores + 4 energy-efficient cores A55. The highest frequency can reach 2.85GHz, and it integrates a 6-core Mali-G610 GPU. A new APU AI unit and an integrated 5G baseband with a maximum download speed of 4.7Gbps.
And the full-blooded version of LPDDR5 memory + upgraded version of UFS 3.1 high-speed flash memory constitutes a three-piece performance set, which is also at the level of a quasi-flagship machine on the market.
Now, let’s take a look at the performance of this Redmi K50.
AnTuTu scored 793,078 points, including 170,178 points for CPU, 310,393 points for GPU, 154,526 points for memory, and 157,981 points for UX.
Master Lu scored 1,033,422 points, surpassing 99% of mobile phones and ranking fourth. The CPU score is 294,474 points, the GPU score is 430,641 points, the memory score is 99,458 points, and the storage score is 208,849.
We chose GeekBench 5, the mainstream processor benchmark software on the market, for testing. The results are 977 for single-core and 3634 for multi-core. Compared with Snapdragon 888, the former is still about 14% behind, and the latter is only 4% worse.
The Dimensity 8100 used in the Redmi K50 in GFXBench is almost the same as the GPU performance of the Snapdragon 888.
In Androbench, the measured continuous read and write speeds are 1879.9MB/s and 1684.91MB/s.
From the above evaluation results, the single-core performance of the Dimensity 8100 is slightly weaker, and the multi-core is the same as that of the Snapdragon 888. Surprisingly, the proudest GPU performance advantage of the Qualcomm Snapdragon series is beaten by the Dimensity 8100. no longer exists.
The MediaTek Dimensity 8100 used in the Redmi K50 has a very good performance, so in theory, it should have a good performance in the game. Next, we will test it for the game.
Glory of the King
In “Honor of Kings”, we changed the frame rate to extremely high, the resolution to ultra-high, and the total picture quality defaulted to high-definition.
The overall picture is maintained at about 120 frames during the game, and the average frame rate is 118 frames.
In “Ace Warrior”, we changed the game’s picture quality and frame rate to the highest, allowing automatic reduction of picture quality and frame rate to be turned off.
During fast battles, excluding frame rate fluctuations caused by death, the average frame rate was 112.
In “QQ Speed”, we changed the game’s image quality settings to ultra-high, the intra-game frame rate and the out-of-office frame rate to very high, and the resolution to ultra-clear.
In the multiplayer game, except for the opening, the overall performance is still very stable, with an average frame rate of 115 frames.
-Now, let’s test “Genshin Impact”, which is known as a baking machine tool by the public. We change the game image quality to extremely high and the frame rate to 60 frames.
During the game of “Genshin Impact”, we randomly fought monsters and ran maps for 15 minutes in multiple scenes, and we could keep it at around 60 frames. As the phone started to get significantly hot, the frame number also gradually dropped to 45 frames, but This performance is still much better than most flagship phones using Qualcomm 888.
At the same time, we also tested the temperature after 15 minutes of turning on Genshin Impact. The infrared thermal imager detected that the temperature next to the camera was the highest, which is generally where the SoC is located, with a maximum of 44.7 degrees Celsius and a body of 41.2 degrees Celsius. . This temperature is far from being hot to the hand. It feels warmer when you hold it in your hand.
This is also thanks to the 3950 square millimeters VC liquid-cooled three-dimensional heat dissipation system of the Redmi K50, 7-layer graphite and copper foil, and other thermally conductive materials. Users do not have to worry about sacrificing performance when playing games.
Of course, other games will not cause much pressure, and the fever will naturally not be so serious.
The K50 uses a rear three-camera solution with the main camera lens of 48MP (Sony IMX582 sensor) + 8MP 119 ° ultra-wide-angle lens + 2MP macro lenses.
IMX582 is also an old friend. Redmi continued to polish it. Redmi used OIS optical image stabilization for the first time in the K50 series.
To put it simply, OIS optical image stabilization can offset the impact of shaking when the person holds the phone without the help of a third-party bracket, thereby reducing the blurring of the image during shooting and improving the filming rate.
At the same time, OIS optical image stabilization can also improve image quality, achieve better nighttime photo effects, and make it easier to take relatively pure samples.
For example, it is easy to cause blurred photos in a low-light environment due to camera shaking. After adding OIS optical anti-shake, in a low-light environment, you can increase the shutter time of the mobile phone, increase the amount of light entering the lens, and shoot better night scenes. Brighter and purer.
Let’s take a look at the Redmi K50 in various scenarios.
The weather has continued to be gloomy recently, and the Redmi K50 has restored the overall atmosphere well. The local details are well preserved, especially the color of the sky and the level of clouds, which have been truly displayed. In addition, there is some edge distortion at the ultra-wide-angle, but it does not affect the overall look.
The overall color reproduction is more accurate when using the main lens to shoot the car model. Even if many books are in different colors in the background, it does not interfere with the car model.
Thanks to the addition of OIS optical image stabilization, the dark light performance of the Redmi K50 has been significantly improved compared with previous generations, and it can also suppress more complex light and shadow, regardless of color reproduction, glare, and noise control. High-end level, Chinese characters can be distinguished. Although there is still some gap with the flagship video phone, you can take it and shoot it if you want to shoot night scenes.
The macro lens has a certain degree of playability, but unfortunately, the white balance adjustment of the macro lens is different from other lenses. The most obvious one is shooting green plants, etc., and you will find that the color of the main camera is not consistent.
The author suggests that there is no special requirement, and the main camera can be used instead of the macro lens to shoot. The same scene is shot with higher pixels and clearer colors, and the color is more comfortable.
The Redmi K50 supports 67W fast charging and has a built-in 5500mAh single-cell battery. The advantages of a single cell are obvious, it is safer, the battery is thinner, the charging heat is lower, and it can also avoid cell loss.
We started collaringfrom 5% of the battery, charged 53% in 20 minutes, and entered the protection charging mode after 90%. The speed slowed down significantly, and it took 58 minutes to charge fully.
Battery life test
We use a professional battery life test tool for the battery life, the battery dog produced by Kuai Technology to test.
For the test items, we chose the limit battery endurance test. We checked all test items, including CPU high voltage, CPU multi-threading, AI recognition, picture browsing, video playback, and web browsing, simulating real usage scenarios and restoring the whole load to the greatest extent. Infinitely close to the real power consumption.
We set the manual 50% brightness, and the test is divided into two stages, from 100% to 20%, which takes 6 hours and 34 minutes, and from 20% to shutdown, which takes 1 hour and 26 minutes.
The superposition of the two battery life test results is 8 hours, which is the same as that of most flagship models in the market, and it is not a problem to use it intermittently for a day.
As the first launcher of the MediaTek Dimensity 8100, the Redmi K50 has brought many surprises, and it still retains Redmi’s tradition of not being stingy with comprehensive stockpiling. It can be called an annual light flagship with no shortcomings.
In addition to its impressive performance, the Dimensity 8100 is not relentless in the face of the Snapdragon 888. Although the single-core performance is slightly weaker, the multi-core performance is comparable, and the GPU performance is unexpectedly superior. At the same time, thanks to the architecture design and energy efficiency optimization, TSMC’s 5nm advanced technology, but also very well controlled power consumption and heat, in the hand experience, the most obvious is that the heat is much lower than the Snapdragon 888/888 Plus.
This is also thanks to the 3950 square millimeters VC liquid-cooled three-dimensional heat dissipation system, 7-layer graphite, copper foil, and other thermally conductive materials equipped on the Redmi K50. Even the “Genshin Impact” with a high load can run at 60 frames for a long time. The maximum surface temperature of the fuselage does not exceed 45 degrees. This performance makes the author look at it with admiration.
Qualcomm, which dominates mobile chips, is now finally facing an opponent, and it must be under pressure. The competition between the two major brands is believed to bring better products to the market in the future.
Redmi K50 has also been upgraded in many aspects, such as screen and fast charging. In this era, when curved screens are rampant, it is even rarer for the Redmi K50 to stick to the straight screen solution. Samsung’s flagship flexible 2K straight screen brings stunning display effects to users. HDR10+, Dolby Vision, and Dolby Atmos Sound blessing, whether looking at photos or swiping videos, the effect is even higher.
Although the rear main camera has used several generations of Sony IMX582 sensors, the Redmi K50 has thoroughly polished it and used OIS optical image stabilization for the first time, so that this lens has a good performance in various scenarios, whether it is The gloomy daytime and the colorful night scene are all in place. It is a pity that the matched macro lens is relatively common, and there is a difference in white balance.
A 67W fast charge can charge a 5500mAh battery to 53% in 20 minutes. It can be fully charged in less than an hour, and it can also provide 8 hours of battery life under a high load.
In general, the performance, screen, image, charging, battery life, etc. of the Redmi K50 series are very promising, as well as Wi-Fi 6 80MHz, Bluetooth 5.3, dual-frequency GPS, full-featured NFC, infrared remote control, X-axis linear motor Wait, it’s all available, no wonder Lu Weibing can shout all kinds of “arrogant” slogans. It is believed that this extremely high-level Redmi K50 will be the first choice for many mainstream users to switch phones in 2022.
