On July 18, Redmi officially released the long-exposed Redmi K70 Extreme Edition, which also follows the normal iteration rhythm of the K series. We know that the K series Extreme Edition is also a series of products that Redmi has added to its volume. This year's Redmi K70 Extreme Edition is no exception. The Dimensity 9300+ processor is paired with the D1 graphics card for a raging game, plus up to 24GB LPDDR5X memory and 1TB UFS 4.0 flash memory, as well as a variety of other configurations, making the actual experience of the Redmi K70 Extreme Edition attract a lot of attention.

It just so happens that at present, IT House has received two mobile phones, the Redmi K70 Extreme Edition with 16GB+1TB Ice Blue color and the Redmi K70 Extreme Champion Edition with 24GB+1TB orange color. Let us take a look at their actual experience through evaluation today.

It should be noted that the Redmi K70 Extreme Edition and the Redmi K70 Extreme Champion Edition in IT House’s hands are almost identical except for the difference in appearance and memory capacity. Therefore, IT House will focus on the standard Redmi K70 Extreme Edition in the evaluation, but will test the performance and game tests with the Redmi K70 Extreme Champion Edition with larger memory capacity.

1. Design

The packaging box of the Redmi K70 Extreme Edition is a regular rectangular box with a black base. The front has the eye-catching golden words "Redmi K70" and the "Extreme Edition" label next to it. The black and gold combination looks more fashionable and cool.

Open the package and look at the phone. The Redmi K70 Extreme Edition has a significant change in appearance design compared to the previous generation K60 Extreme Edition. It adopts a new borderless aesthetic design, which is the unified design language of the K70 family. The most eye-catching thing on the back of the phone is the borderless ultra-large glass Deco 2.0, which is matched with the glass material to bring a more transparent and simple visual effect.

The triple-camera lens and flash are designed like the portholes of a spaceship, with upper and lower dividing lines. The metal camera ring has an extremely narrow inner C-angle and is anodized in different colors. The four circular bright edges in the same color as the body have a shallow decorative effect and are full of details.

The back of the phone is made of frosted glass with a delicate touch. It is simple and hazy, and the edges are curved through four curved surfaces, making it more elegant.

The front of the phone is a 6.67-inch screen with an ultra-narrow visual equilateral design, which brings Redmi's narrowest 1.9mm chin and a more transparent front visual experience.

In terms of the middle frame, the Redmi K70 Extreme Edition has upgraded the high-strength aluminum alloy matte frame. Although it is a right-angle middle frame, the upper and lower parts are transitioned through extremely narrow curves and the front and rear panels, thus ensuring the softness of the feel.

In terms of body elements, there is only an antenna partition on the left side and no buttons. The right side has the volume button and power button. The top of the body has a microphone and infrared sensor, and the bottom has a speaker opening, USB port, microphone and SIM card slot.

At the same time, the dimensions of the Redmi K70 Extreme Edition are 160.38×75.14×8.39 mm and the weight is 211g, which feels a bit heavy.

In addition to the Redmi K70 Extreme Edition, IT Home also got the Redmi K70 Extreme Champion Edition, which is a joint customized model between Redmi and Lamborghini, and is also an old tradition of Redmi. The packaging box is different from the standard Extreme Edition. It is larger and longer, more like a gift box set. In addition to the Redmi-related elements on the front of the packaging, the most eye-catching is the shield logo of Lamborghini Automobile SQUADRA CORSE.

After opening the package, the accessory storage box inside is also a customized element of Lamborghini, including the instruction manual, the card removal pin and the card for the card removal pin, which are also individually designed. A Lamborghini sports car-style mobile phone case is also included. The mobile phone case combines multiple materials such as matte plastic, plain leather, glass, and Kevlar, and there is also a metal Lamborghini shield. It can be said that it is very thoughtful.

Looking at the phone itself, the back of the Redmi K70 Extreme Champion Edition uses Lamborghini's iconic Y-shaped line design, symbolizing speed and passion.

The Deco part and the lower part of the camera are a contrasting color combination of orange and black, which is very eye-catching and full of vitality and power.

Looking at the camera lens and flash again, the high-gloss metal decorative ring with golden inner chamfers and the black camera lens form a black and gold combination, bringing a light luxury style that also matches the overall temperament of the phone.

Although there are many customized elements on the back of the phone, they are all harmonious and orderly, without any glare pollution, and it looks very high-end.

The middle frame is made of pure black matte aluminum alloy, which feels very delicate. The diagonal texture design of the power button also matches the overall style of the phone.

After turning on the phone screen, you can see that the system theme of the Redmi K70 Extreme Champion Edition is also a cool black and gold style customized by Lamborghini. Each system icon has been specially designed and full of details.

Overall, the Redmi K70 Extreme Edition has a simple and stylish borderless aesthetic design with a sense of technology and exquisite workmanship. The overall appearance is great value for money for a product at this price. The Redmi K70 Extreme Champion Edition has a more dynamic and passionate Lamborghini custom design with a stronger sense of quality. For students who love sports car culture, it is also not to be missed.

2. Performance Test

In terms of performance, the Redmi K70 Extreme Edition uses the MediaTek Dimensity 9300+ flagship processor, with a full-core CPU architecture, including 1 [email protected] core, 3 [email protected], and 4 [email protected] cores, of which the 3.4GHz main frequency is the highest in Android. It also has a new generation flagship 12-core GPU Immortalis-G720, which provides powerful graphics processing capabilities.

Compared with the previous generation Dimensity 9200, the Dimensity 9300+ has a 40% increase in CPU performance, a 33% decrease in power consumption, a 46% increase in GPU performance, and a 40% decrease in power consumption.

At the same time, taking the Redmi K70 Extreme Champion Edition as an example, it is also equipped with 24GB LPDDR5X memory and 1TB UFS 4.0 flash memory, which is a luxurious configuration.

In the actual test, IT Home first used AnTuTu Benchmark V10 to run the test. The Redmi K70 Extreme Champion Edition scored 2250401 points, including 522434 points for CPU and 917166 points for GPU. Then it was tested with GeekBench 6. It can be seen that the single-core score is 2284 points and the multi-core score is 7634 points, which is also quite eye-catching. Then the storage performance test was also done with AnTuTu Benchmark. The Redmi K70 Extreme Champion Edition scored 231348 points, including a sequential read speed of 4179.7 MB/s, a sequential write speed of 3939.3 MB/s, and random read and random write speeds of 2049.0 MB/s and 1658.0 MB/s, respectively, which gave full play to the performance of UFS 4.0 flash memory.

After the running test, the next step is to use games to test the performance of the Redmi K70 Extreme Champion Edition. We directly played "Genshin Impact", which has high performance requirements. Before the test, we set the game's image quality options to the highest, the game frame rate to 60fps, and set the Redmi K70 Extreme Champion Edition phone performance to violent mode, and then played the game for 30 minutes. The first 15 minutes of the game were spent running around in Xumi City, and the last 15 minutes were spent fighting monsters in the wild near Xumi City.

After 30 minutes, the average frame rate of the Redmi K70 Extreme Champion Edition running the game was measured to be 59.71fps. Looking at the frame rate curve, the overall situation is still very stable, with basically no large frame rate fluctuations. The actual gaming experience is also very smooth, and there is no feeling of frame drops throughout the whole process.

Looking at the CPU core scheduling of Dimensity 9300+, we can see that during the game, four Cortex-X4 cores are basically working, mainly fluctuating between 0.7GHz and 2.1GHz. One Cortex-X4 core with a maximum frequency of 3.4GHz can occasionally reach 2.4GH-2.8GHz, but it quickly falls back. The other four Cortex-A720 cores basically maintain a frequency of 0.8GHz throughout the whole process. It can be seen that under the Dimensity 9300+ all-core design, the core scheduling strategy for dealing with "Genshin Impact" is still relatively simple and crude, but the effect is also immediate.

So how is the temperature control of the Redmi K70 Extreme Champion Edition under the wild performance of all big cores? During the game, the editor measured the highest temperature of the fuselage at 41.8℃, which appeared near the rear camera, which is not too high. In the actual gaming experience, you can feel the rolling heat flow, but it is not hot to the point of burning your hands.

According to the results of the software test, during the test of "Genshin Impact", the average power consumption of the Redmi K70 Extreme Champion Edition was 5.1W, which is not too high.

The above is a regular "Genshin Impact" test. The Redmi K70 Extreme Champion Edition is also equipped with a new customized "Rage Game Independent Display D1 Chip" and uses a 12nm process. For the first time, Redmi has used its self-developed AI Super Vision Engine in the game, achieving a full-blooded gaming experience brought by super-resolution and interpolation. With the "Rage Engine 3.0", it can dynamically adjust the output between the SoC and the independent display in the performance scheduling strategy, connect the dual cores, and deeply coordinate the software and hardware.

Specifically, for "Genshin Impact", the super-resolution frame insertion strategy can be dynamically adjusted to achieve 1.5K resolution + 120fps full-level image quality. In actual use, you need to select GPU Settings-Custom-Resolution-Extreme in the game space of the Redmi K70 Extreme Champion Edition, and then turn on the violent mode-image enhancement-super image quality in the game toolbox.

After turning on the function and entering the game, you can clearly see that the game screen is clearer and sharper than when it is not turned on. For example, in the scene below, after turning on the super picture quality, the details of the distant mountains are obviously more, and the color transition of the sunset sky is also richer.

After turning on ultra-high quality graphics and entering the game, you can see that the average frame rate of the game output by the mobile GPU is 40.33fps.

But when actually playing, with the help of interpolation technology, the frame rate that players can feel has actually reached 120fps, which can be seen by turning on the real-time refresh rate of the mobile phone screen.

At the same time, it can be seen that after turning on the super picture quality, the overall load of the Redmi K70 Extreme Champion Edition running "Genshin Impact" is obviously a level lower. The editor did a small test and the average power consumption was only 4.5W.

It can be seen that the combination of the D1 chip with the game super-resolution and interpolation functions has indeed improved the gaming experience of the Redmi K70 Extreme Champion Edition. In addition to "Genshin Impact", mainstream games such as "Star Dome Railway", "Honor of Kings", "Peace Elite", "CrossFire - Gun King", "Dark Zone Breakout", "Call of Duty Mobile", "QQ Speed ​​Mobile", and "Minecraft" all support super-resolution and interpolation concurrently, bringing a concurrent experience with both ultra-high definition and ultra-high fluency.

In addition to "Genshin Impact", IT House also conducted a test on "Honor of Kings". The first test was a regular test, in which a game of about 10 minutes was played under the highest picture quality option.

After the test, we can see that the Redmi K70 Extreme Champion Edition can run "Honor of Kings" at an average of 120.14fps, and the frame rate curve is quite stable with almost no fluctuations. The entire game process is also very smooth.

During the game, the four Cortex-X4 cores are still the main processors, and the maximum frequency can occasionally reach 2.8GHz. The average power consumption during the game is 3.9W, which is also not high.

In addition, IT Home measured the maximum temperature of the body during the game to be 38.0℃. There was a more obvious sense of warmth when playing, but it was not hot at all.

After turning on "super picture quality", with the support of super resolution + interpolation concurrency, the actual game frame rate of "Honor of Kings" can reach 144fps, which also fully meets the maximum refresh rate of the screen of the Redmi K70 Extreme Champion Edition.

Overall, with the support of Dimensity 9300+ and a series of stacked materials, the performance of the Redmi K70 Extreme Edition is a high-end flagship level with abundant energy. At the same time, it also has the magical skill of super-resolution frame insertion and concurrency of the independent display D1 chip. It can be said that there is basically no game on the market that the Redmi K70 Extreme Edition cannot handle, let alone daily use.

3. Image Function Experience

In terms of imaging, the Redmi K70 Extreme Edition is equipped with a triple-camera system with a 50-megapixel super dynamic main camera. The main camera uses a 1/1.56-inch Sony IMX906 sensor with a single pixel size of 1.0μm. At the same time, there is Xiaomi AISP technology, which brings the Redmi K70 Extreme Edition an improved experience in functions such as high-speed capture, textured tones, low-light shooting, and textured portraits.

Let's take a look at the sample photos. First, the daytime scene. The photo below was taken around 9 o'clock in the morning, with the sun shining obliquely on the tree. The Redmi K70 Extreme Edition restored the transparency under the sunlight at that time very well, and the color was closer to what you see in real life, not too bright.

Look at the picture below. The shooting environment was cloudy. The exposure of the Redmi K70 Extreme Edition is still relatively accurate, and the color is still close to what you see in reality, especially the green part, which captures the lush feeling of the cloudy day after the rain.

Zoom in to see the details. The large characters on the bus stop billboard in the distance can be seen clearly, but the small characters have become blurred. The wall texture on the building behind can also be basically seen clearly. The resolution is still good.

Take another photo in this scene using the 50-megapixel full-pixel mode. There is a slight difference in the imaging style. The picture exposure seems to be more sufficient under full-pixel mode and is brighter than what the human eye sees.

Zooming in the photo, the outlines of the small characters are clearer, but still not clear. The texture of the tiles on the wall behind is also richer, and the resolution has indeed improved.

In terms of macro, you can see that the F/1.6 aperture of the main camera can bring a very good background blur effect, and the focus of the dandelion is also very clear.

Next is a scene with strong light contrast. The photo was taken from the underground garage. In the near distance, there is highlight from the skylight, in the middle is a dark environment, and in the distance there is highlight outside the garage. The photos taken by the Redmi K70 Extreme Edition show a good dynamic range effect. The dark areas are bright enough and the highlights are not overexposed.

As for night samples, the editor first took a photo in front of a shopping mall at night. The photos taken in standard mode are bright and clear, the overall picture is very pure, there is basically no visible noise, and the dynamic range performance is also good, the dark part of the picture is bright enough, and the highlight part does not overflow. The picture looks more natural.

For example, in the photo below, under the illumination of lights of various colors, the ambient light is very complex. The photo taken directly from the Redmi K70 Extreme Edition well restores the color atmosphere of the scene at that time. The colors are bright and vivid, and the viewing experience is very good.

At the same time, looking at the details, the colors of the clothes of pedestrians in the distance and the entertainment facilities accurately restore the colors seen by the human eye at the time, indicating that even under complex lighting conditions, the Redmi K70 Extreme Edition can maintain the accuracy of color reproduction.

In addition to the basic shooting experience, it is also worth mentioning that the Redmi K70 Extreme Edition also supports the all-object tracking function, which can help you keep the focus well when shooting moving objects. For example, when I was shooting a macro of a dandelion, the dandelion was always shaken by the wind, and it was difficult to focus at first. However, after turning on the all-object tracking mode, the Redmi K70 Extreme Edition can always lock the focus on the shaking dandelion, so that it can be shot clearly.

4. Other functional experience

In the process of using the Redmi K70 Extreme Edition, another thing that impressed me was its screen. The Redmi K70 Extreme Edition is equipped with the latest generation of 1.5K (2712×1220 resolution) flagship straight screen, which supports 144Hz high refresh. One of the highlights of this screen is its eye protection characteristics. It continues Qingshan Eye Care's "medical and engineering integration" eye protection concept, supports 3840Hz ultra-high frequency PWM dimming, and has less risk of using stroboscopic light in dark environments. During the test, the editor used 240fps slow-motion video in a dark environment to shoot the Redmi K70 Extreme Edition and another competing mobile phone at the same time. It can be seen that under the high frame rate viewfinder, the screen surface of the competing mobile phone has obvious screen flicker, while the Redmi K70 Extreme Edition can hardly see flicker.

In terms of display, the full-screen brightness of this screen has been increased to 1600nits, reaching the industry-leading level. During the test, IT Home also successfully stimulated the screen brightness to 1536nit, at which time the highlight of the sky displayed in the picture was very bright.

Finally, let’s talk about battery life and charging. The Redmi K70 Extreme Edition is equipped with the self-developed fast charging chip Pengpai P2 and the self-developed power management chip Pengpai G1, and adopts a 120W fast charging + 5500mAh large battery combination.

IT Home conducted a simple battery life test on the Redmi K70 Extreme Edition. The entire test was carried out in a Wi-Fi environment. The screen brightness and system volume were set to 50%. The phone was tested in balanced mode with Bluetooth turned on.

First, use Bilibili to watch a 1080P high frame rate movie for 45 minutes, consuming 3% of power.

Then I browsed Weibo for another 15 minutes, which consumed 2% of the battery.

Then watch short videos on TikTok for 20 minutes, which consumes 2% of the battery.

Finally, I browsed IT Home for 10 minutes, consuming 1% of the power.

After a total of 90 minutes of testing, the Redmi K70 Extreme Edition consumed 8% of power, leaving 92% of power. This battery life level is still excellent.

The same is true of my experience when testing. I can still use the phone for a whole day with about 20% of the battery remaining under normal and slightly higher intensity, so I don't have to worry about battery life. In addition, because I need to do a charging test, I started discharging the phone when the battery was still 75%. I turned on the highest quality "Genshin Impact" and the flash at the highest screen brightness (the phone was left stationary without any operation), and it still took more than four hours to discharge the battery.

In terms of charging, it was tested that the standard 120W charger was used. The Redmi K70 Extreme Edition was fully charged from 0 to 100% in only 27 minutes, of which 30% could be charged in the first 5 minutes.

Conclusion

After a period of experience, IT Home believes that Redmi has once again used their "huge energy roll" character to come up with a product that is basically impeccable in the performance flagship track. The combination of Dimensity 9300 + processor + LPDDR5X memory and UFS 4.0 flash memory allows it to compete with those high-end flagships priced above 4,000 in terms of performance. The 1.5K resolution and 144Hz refresh rate screen is also quite decent, and 3840Hz ultra-high frequency PWM dimming is also used. In addition, the combination of 120W+5500mAh is even further than the previous generation. In terms of imaging, at least the quality of the 50-megapixel super dynamic main camera is sufficient for most users' daily use. At the same time, there is a solid body of glass + aluminum alloy. In short, if the Redmi K70 Extreme Edition is a "bucket machine", it is also a "bucket machine" that lengthens every wooden board of the bucket.

What's more, the Redmi K70 Extreme Champion Edition, which is blessed with the belief in supercar culture, and the detailed joint customization elements of Lamborghini, is believed to attract the attention of many users who love sports car culture in the market.

In the mid-to-high-end market in the second half of the year, the Redmi K70 Extreme Edition has already made its debut, and it depends on how other competitors respond.
