Redmi K70 series can be said to be very popular, from the sales report of the opening sale to the standard version of the K70 became the single product sales champion during the 618 promotion, all can show the excellent product power of the K70 series. Now the more powerful Redmi K70 Ultra is also coming, let's follow this article to see what kind of performance it can bring when equipped with the flagship Mediatek Dimensity 9300+ core.
Flagship dual-core, gaming experience more enjoyable
Redmi K70 Ultra equipped with Mediatek Dimensity 9300+ believe that we are more familiar with, the use of four Cortex-X4 ultra-large core and four A720 core of the full large-core architecture, one of the X4 ultra-large core maximum frequency increased to 3.4GHz.
Let's take a look at the Redmi K70 Ultra's gaming performance. Turn on Berserk Mode in Game Assistant at 25 degrees room temperature. In the game “Original God” set the highest quality (864P), the frame rate is set to 60 frames, using the Night Orchid Early Yuzu Twin Winds resonance. The average frame rate of the Redmi K70 Ultra was 59.4 frames for a half-hour run through Sumeru City, which is almost a straight line on the frame rate chart, and the actual experience was so smooth that I can say it was “no surprise”.
The Rampage Engine 3.0 on the Redmi K70 Ultra is not only a software enhancement, but also a hardware enhancement. The newly customized Rampage Gaming D1 chip has a 12nm process that delivers better power efficiency. With the Berserk Engine 3.0, the Redmi K70 Ultra can support 1.5K Super Score and 120 frames concurrently in ProtoGods, and the official statement says that the smooth experience can last up to 1 hour.
The frame insertion function will always have a touch delay, the actual test Redmi K70 Ultra 120 frames mode on the touch delay control is very good, but you need to set the GPU in the game space to “extreme”, the game assistant to open the “super quality”, although a bit cumbersome, but the experience will be more comfortable after the setup.
In terms of heat dissipation, the Redmi K70 Ultra is equipped with a new-generation Ice Seal heat dissipation system, which covers the back of the screen and the surface of the center frame with a large-area, high heat flux graphite, which improves the thermal conductivity of the graphite material by 15 percent compared to the previous generation. In the first half hour of the Original God test, the maximum temperature of the fuselage reached 44.2˚C, which is a good proof that the heat inside the fuselage is being conducted out well.
The GPU is even more loaded in Star Dome Railroad, where the test environment remains the same and the game resolution is 755 P. The Redmi K70 Ultra's half-hour Golden Hour runtime averaged 55 fps. For those of you who play StarDome regularly, you should know that the load of the Golden Hour run is very high, and the Redmi K70 Ultra's power consumption reached 7.8W, with the body temperature reaching 47.8˚C.
The frame rate performance of the Redmi K70 Ultra Star Dome Railway can be summarized as follows: in the first 12 minutes, the performance is very aggressive, with 57.3 frames and power consumption of 8W; in the 12-25 minutes, perhaps the heat is coming up, so the CPU frequency is actively reduced, and the average frame rate drops to 54.9 frames, with power consumption of 7.8W; and in the last 5 minutes, perhaps the heat has reached the threshold, so the average frame rate drops to 54.9 frames, with power consumption of 7.8W. In the last 5 minutes, perhaps the heat has reached the threshold, and the super-core locks up, although the smoothness of the screen has decreased, but the frequency of the A720 core remains unchanged, the scheduling is still quite aggressive.
To summarize the performance of the Redmi K70 Ultra, with the dual-core Mediatek Dimensity 9300+ and “Rampage Gaming Solo D1 Chip”, along with the Rampage Engine 3.0, it can give you a more extreme gaming experience. Even though Redmi K70 Ultra has better heat dissipation, it can't resist more heat from the aggressive tuning, so maybe with a heat dissipation back clip, you can enjoy the game.
Excellent texture in the details
Redmi K70 Ultra continues the design language of “Borderless Aesthetics”, the lens module adopts an oversized glass design, and the quad-curved arc is more rounded than the K70 from the naked eye's point of view. The lens has also evolved into a porthole design similar to that of a spaceship, and the overall texture is more recognizable at the same time.
In terms of color scheme, Redmi K70 Ultra has a new color scheme “Ice Glaze” in addition to the two classic color schemes “Clear Snow” and “Ink Feather”. The light blue color is just like the name of this color scheme, which will give you a hint of refreshing coolness in this hot summer. Most importantly, this frosted glass isn't prone to fingerprints, which is worth a nod.
The front of the Redmi K70 Ultra comes with a 6.67-inch 1.5K flagship straight screen with a resolution of 2712x1220 and supports up to 144Hz high refresh rate. The screen utilizes FIAA in-screen alignment technology, which reduces the screen's chin width to 1.9mm for a more immersive viewing experience with a higher screen-to-body ratio. We tested the color calibration using DisPlay CAL, and it's still very good.
It is worth mentioning that the Redmi K70 Ultra's screen is also optimized in the dimming strategy, upgraded to 3840Hz high-frequency PWM dimming at low brightness, which reduces the risk of stroboscopic flickering and better protects the eyes of “night owls”.
Other experiences are also good
Experience first of all to talk about a heavy upgrade, Redmi K70 Ultra for the first time in the no caulking adhesive three sides of the machine without glue to achieve IP68 waterproof program, in the screen, back cover, the middle frame of the seal, and high permeability pressure relief valve, daily use without fear of accidental splashing bitch.
Endurance, Redmi K70 Ultra is equipped with a 5500mAh high-capacity battery, charging is equipped with 120W flash charging, from this specification can say goodbye to endurance anxiety, as well as self-developed fast-charging chip surging P2 and power management chip G1, more can show excellent endurance ability.
Tested Redmi K70 Ultra in the open high-speed charging mode, 5 minutes from 1 % to 31% capacity, 10 minutes to half, and finally in 25 minutes at the beginning of the charge to 100% capacity. It's fast, but the Redmi K70 Ultra is still quite hot when fully charged with Extreme Mode on, so it's something to keep an eye on.
Finally, let's talk about the image, Redmi K70 Ultra is equipped with a 50-megapixel IMX906 main camera with a 1/1.56-inch base, and Xiaomi AISP, which has been optimized and improved in many aspects, such as shading, portraits, and dark-light shooting. There is also an 8-megapixel ultra wide-angle and 2-megapixel macro lens to meet different shooting needs.

Summary
The Redmi K70 Ultra is powered by the Mediatek Dimensity 9300+ flagship chip, which, along with the Rampage Engine 3.0, brings more aggressive performance scheduling, which is also well demonstrated in two games, Proto-God and Star Dome Railroad. The aggressive scheduling is still better on cooling, although there is an upgraded Ice Seal cooling system, so perhaps with a cooling back clip you can game without a hitch.
Overall, the Redmi K70 Ultra is a more performance-oriented phone, with the flagship dual-core paired with aggressive performance scheduling to deliver smoother performance in games, making it ideal for those who focus on the gaming experience. Other aspects such as appearance and texture, screen performance, battery life and so on have good performance, I believe this Redmi K70 Ultra can give you more surprises.
