I. Foreword: The first Redmi K50 equipped with Tianji 8100
To say that the most successful mobile phone on the market last year, Redmi K40 is definitely a strong competitor, with exquisite design, no shortcomings of the strong specifications, once launched, it has attracted market attention, in the 1999 yuan price point for a year as a "goalkeeper", called "a generation of divine machine" is not excessive.
In this context, the new generation of Redmi K50 is naturally "expected", the official is also constantly warming up, Redmi brand general manager Lu Weibing is shouting out the slogans of "fierce imagination" and "comprehensive welding door".
Now, the Redmi K50 series is finally officially born, and we have also got two versions of Redmi K50 and Redmi K50 Pro in advance, respectively, equipped with MediaTek Tianji 8100 and Tianji 9000.
Here, let's try the standard version of the Redmi K50.
The core configuration of Redmi K50 is a performance three-piece set composed of Tianji 8100 + full blood version of LPDDR5 memory + upgraded version of UFS 3.1 high-speed flash memory, which is also the world's first model to use "Fa Ge" MediaTek Tianji 8100, with the front of the standard Snapdragon 888/888+.
The positioning of Tianji 8100 is the flagship, using TSMC 5nm manufacturing process, integrated eight-core A78+A55 CPU, the highest frequency reaches 2.85GHz, integrated six-core Mali-G610 GPU, integrated new APU AI unit than Tianji 1200 to 275%, integrated 5G baseband, the highest download speed of 4.7Gbps.
Tianji 9000 and Snapdragon 8 have played back and forth on the flagship platform, the performance is basically flat, and it is even exceeded in multi-core CPUs and other aspects, and the energy efficiency is a big lead.
It can be said that MediaTek has "held back" for so many years, and finally launched a chip that can surpass Qualcomm Snapdragon, so that the market has more choices, which is also the situation of "healthy competition" that users expect.
The mission of Tianji 8100 is to pull down the Snapdragon 888/888+, whether it is performance or energy efficiency, as well as terminal price. As for whether it can be done, let's move on.
In addition to performance, Redmi is also committed to popularizing 2K screens. The Redmi K50 uses the same Samsung AMOLED flexible direct side screen as the K50 Pro.
It has a resolution of 3200×1400, a refresh rate of 120Hz, a PPI of 526, and also has an ambient color temperature, DC anti-strobe dimming, 16,000 levels of automatic brightness adjustment, and supports HDR10+, Dolby Vision Dolby Vision, factory primary color screen, etc., which is completely flagship on the market.
In addition, Redmi K50 also has a 5500mAh super battery, 67W fast charging, charging endurance is completely free of the "burden" of 2K high brush.
Next, let's take a look at the specific performance of this Redmi K50 equipped with Tianji 8100, the following figure is the parameter information:
Second, the appearance: silver color matching has texture The rear three-shot shape is very chic
The overall color of the outer box is white, very simple, the front is only gold K50, the side is printed with 67W and 2K, indicating that it supports 67W fast charging, and the screen adopts 2K resolution.
The K50 we received was a silver color scheme, a double-sided glass body, a frosted surface, and a metallic reflection, with a very distinctive square and round collision design, which looked highly advanced.
The Front of the Redmi K50 uses a 6.67-inch Samsung AMOLED flexible direct 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 direct screen, which can improve the display effect while also optimizing for edge mistouching.
There are also up to 16,000 levels of automatic brightness adjustment, coupled with ambient color temperature sensing, so that users will be comfortable to watch the screen outdoors indoors.
This screen also supports DC anti-strobe dimming, users in a low-brightness environment, not afraid of hurting the eye.
Sony's IMX596 sensor is used in the front-facing excavation area, and 20 megapixels can bring a sharper portrait effect.
At first glance, the author thought that the K50 used the same narrow border on all four sides, and when I looked closely, I found that the upper and lower sides were slightly wider, but the overall visual effect was very good, with a strong sense of unity and immersion.
Camera local details, K50 uses the main lens of 48 million pixels Sony IMX582 sensor, with 8 million pixels of 119 ° large wide angle lens, 2 million pixel macro lens, composed of 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 on many flagship machines.
Top and bottom local details, in addition to the regular USB-C interface and SIM card slot, the K50 also supports Dolby Atmos stereo dual speakers and infrared.
The K50's physical buttons are on the right side of the fuselage, with the volume plus or minus keys on the top and the power buttons supporting fingerprint recognition on the bottom.
The family barrel is packed with a SIM pin, charger, data cable, instruction manual and water cover.
Third, performance test: Tianji 8100 strength is good performance reached the flagship level
Redmi K50 is equipped with MediaTek Tianji 8100, using TSMC 5nm manufacturing process, the processor is 4 A78 large core + 4 energy efficiency core A55 composed of 8 cores, the maximum frequency can reach 2.85GHz, integrated 6-core Mali-G610 GPU, a new APU AI unit, and integrated 5G baseband, the highest download speed of 4.7Gbps.
And the full blood version of LNDDR5 memory + upgraded version of UFS 3.1 high-speed flash memory to form a performance three-piece set, in the market also belongs to the level of quasi-flagship machines.
Now, let's take a look at the performance of this Redmi K50.
- Ann Rabbit
An Tutu ran a score of 793078 points, including a CPU score of 170178, a GPU score of 310393, a memory score of 154526, and a UX score of 157981.
--Master Lu
Master Lu ran a 1033422 point, surpassing 99% of mobile phones and ranking 4th.
The CPU score is 294474 points, the GPU score is 430641 points, the memory score is 99458 points, and the storage score is 208849 points.
——GeekBench
We chose GeekBench 5, the more mainstream processor benchmark software on the market, for testing, and gave the results of single-core 977 and multi-core 3634, which is about 14% behind the Snapdragon 888 and only 4% behind the latter.
——GFXBench
The Performance of the Tianji 8100 in GFXBench, adopted by the Redmi K50, is almost on par with the GPU performance of the Snapdragon 888.
——AndroBench
In Androbench, the measured continuous read and write speeds were 1879.9MB/s and 1684.91MB/s, respectively.
From the above evaluation results, the single-core performance of Tianji 8100 is slightly weaker, and the multi-core is basically equivalent to the Snapdragon 888, and the unexpected is that the GPU performance advantage that Qualcomm Snapdragon series is most proud of, which is beaten by Tianji 8100.
Redmi K50 uses mediatek Tianji 8100, the overall performance release is very in place, then the game theory should also have a good performance, and then we will test the game.
Fourth, the game experience: a number of games support 120Hz temperature control is better
- Glory of Kings
In Honor of Kings, we changed the frame rate to extremely high, the resolution to ultra-high, and the total picture quality defaulted to HD.
During the game, the overall picture remains at around 120 frames, with an average frame rate of 118 frames.
- Ace Warrior
In Ace Warrior, we changed the game's screen quality and frame count to the highest, allowing for automatic reduction in image quality and frame rate off.
During the fast war, excluding the frame rate fluctuations caused by death, the average frame rate is 112 frames.
——QQ Flying Car
In "QQ Flying Car", we changed the picture quality setting of the game to ultra-high, the in-game frame rate and the external frame rate to extremely high, and the resolution to ultra-clear.
In multiplayer matches, the overall performance is still very stable, with an average frame rate of 115 frames, except for the opening.
- The original god
Now let's test the original god, which is known as the grill tool, and we change the game image quality to extremely high quality and the frame rate to 60 frames.
During the game of "Original God", we randomly played monsters in multiple scenes and ran pictures for 15 minutes, which could basically be maintained at about 60 frames, and as the mobile phone began to heat up significantly, the frame rate began to gradually drop to 45 frames, but this performance was still much better than most flagship mobile phones that used Qualcomm 888.
At the same time, we also tested the temperature 15 minutes after opening the "Original God", through the infrared thermal imager detection, the temperature next to the camera is the highest, which is generally where the SoC is located, the highest is 44.7 degrees Celsius, the fuselage is 41.2 degrees Celsius. Such a temperature is far from being hot, and it is a warm feeling to hold on the hand.
This is also thanks to the Redmi K50's 3950 square millimeter VC liquid-cooled stereoscopic heat dissipation system, 7 layers of graphite and copper foil and other thermally conductive materials, so that users do not have to worry about sacrificing performance when playing games.
Of course, other games will not cause so much pressure, and the fever will naturally not be so serious.
Fifth, take pictures: for the first time equipped with OIS optical image stabilization, deep polishing IMX582
The K50 uses a rear triple-camera solution for a main lens of 48 million (Sony IMX582 sensor) + 8 million 119° ultra-wide angle lens + 2 million macro lens.
The IMX582 is also an old friend, And Redmi continues to polish it deeply, and Redmi uses OIS optical image stabilization for the first time in the K50 series.
In simple terms, OIS optical image stabilization can offset the impact of jitter on the shooting when the character is holding the phone without the help of a third-party bracket, thereby reducing the blurry image situation during shooting and improving the film completion rate.
At the same time, OIS optical image stabilization can also improve the image quality, achieve better night photography effect, and make it easier to take a relatively pure sample.
For example, in the environment with weak light, it is easy to blur the photo due to camera shaking, after adding OIS optical image stabilization, in the environment with weak light, you can increase the shutter time of the mobile phone, so that the amount of light entering the lens is increased, and the night scene taken is brighter and purer.
Let's take a look at how the Redmi K50 performs in various scenarios.
Main camera 1X
Ultra-wide angle 0.6X
Recently, the weather has continued to be gloomy, Redmi K50 has better restored the overall atmosphere, local detail preservation is also in place, especially the color of the sky, the level of clouds, have been truly displayed, in addition to some edge distortion under the ultra-wide angle, but does not affect the overall look.
When using the main lens to shoot the car model, the overall color reproduction is more accurate, even if there are more books of different colors in the background, there is no interference with the car model, the object is clearly layered, and the details of the car model are accurately displayed.
Nightscape sample effect
Thanks to the addition of OIS optical image stabilization, the low light performance of the Redmi K50 has been significantly improved compared with previous generations, and it can be suppressed against more complex light and shadow, whether it is color reproduction or glare, noise control, it is a high-end level, and the Chinese characters can be clearly distinguished. Although there is still some gap with the flagship image phone, if you want to shoot night scenes, you can completely take pictures as you like.
Macro sample effect
Macro lenses have a certain degree of playability, but unfortunately, the white balance tuning of macro lenses is different from other lenses, the most obvious is to shoot green plants, etc., you will find that the color of the main camera is not consistent.
The author suggests that there is no special need, you can use the main camera to replace the macro lens shooting, the same scene main camera to shoot the picture pixels are higher and clearer, the color is more comfortable.
Sixth, charging and battery life: 5500 mAh battery can provide 8 hours of battery life
The Redmi K50 supports 67W fast charging and has a single battery of 5500 mAh built-in. The benefits of a single cell are obvious, with safer batteries, thinner batteries, lower charging heat, and avoiding cell losses.
- Charging
We start charging from 5% charge, charging to 53% in 20 minutes, and then entering the protected charging mode after 90%, the speed is significantly slower, and it takes a total of 58 minutes to fully charge.
- Endurance test
For the battery life, we use a professional battery life test tool - battery dog produced by Fast Technology for testing.
In terms of test items, we selected the limit battery life test, checked all test items including CPU high voltage, CPU multi-threading, AI recognition, picture browsing, video playback, and web browsing, simulated real use scenarios, maximized the restoration of real load, and infinitely close to the real power consumption.
We set the manual 50% brightness and the test was divided into two phases, from 100% to 20%, which took 6 hours and 34 minutes, and from 20% to shutdown, which took 1 hour and 26 minutes.
The two endurance test results are superimposed for a total of 8 hours, which is basically equivalent to the endurance of most flagship models on the market, and intermittent use is not a problem.
Vii. Summary: Tianji 8100 can hit the fever low, K50 will become a divine machine
As the launcher of the MediaTek Tianji 8100, the Redmi K50 has brought a series of surprises, still retaining the tradition of Redmi's unsparing and comprehensive stacking, which can be called the annual light flagship without shortcomings.
Tianji 8100 performance in addition to good performance, in the face of Snapdragon 888 is not soft, although the single-core performance is slightly weaker, but the multi-core performance is comparable, GPU performance is unexpectedly surpassed, while benefiting from architecture design, energy efficiency optimization, TSMC 5nm advanced technology, but also very in place to control the power consumption and heat, take the experience in hand, the most obvious is that the heat is much lower than the Snapdragon 888/888 Plus.
This is also due to the Redmi K50 equipped with a 3950 square millimeter VC liquid-cooled stereoscopic heat dissipation system, 7 layers of graphite and copper foil and other thermal conductive materials, even if the load of the "Original God", can run for a long time at 60 frames, the fuselage surface temperature is not more than 45 degrees, such a performance, let the author impressed.
Qualcomm, which dominates the mobile chip, is now finally meeting the opponent, and it will definitely feel pressure. The competition between the two major brands believes that it will bring more excellent products to the market in the future.
The Redmi K50 has also been upgraded in many ways such as screen and fast charging. In this era of curved screens, Redmi K50 can adhere to the use of straight screen scheme is even more rare, Samsung flagship flexible 2K direct screen for users to bring a gorgeous display effect, HDR10+, Dolby Vision Dolby Vision with Dolby Atmos Dolby Atmos blessing, whether looking at photos or brushing videos, the effect is more layered.
Although the rear-facing main camera uses several generations of Sony IMX582 sensors, the Redmi K50 has polished it deeply and used OIS optical image stabilization for the first time, so that this lens has a good performance in various scenes, whether it is gloomy daytime or colorful night scenes, it is very well grasped. Unfortunately, the matching macro lens is relatively ordinary, and there is a difference in white balance.
With a 67W fast charge, it can charge a 5500 mAh battery in 20 minutes, fill up with blood in less than an hour, and provide 8 hours of battery life under high load.
In general, the performance of the Redmi K50 series, screen, image, charging, battery life, etc. are very material, as well as Wi-Fi 6 80MHz, Bluetooth 5.3, dual-band GPS, full-featured NFC, infrared remote control, X-axis linear motor, etc., are readily available, no wonder Lu Weibing can shout out a variety of "arrogant" slogans.
It is believed that this high-level Redmi K50 will be the first choice for many mainstream users to change their machines in 2022.
In terms of price, the 8GB+128GB version is 2399 yuan, the 8GB+256GB version is 2599 yuan, and the 12GB+256GB version is 2799 yuan, all of which have four color matching options: ink feather, silver trace, environment and glow.
