The power of 20000 rpm fan! Red Devils 7S Game Phone Evaluation： Snapdragon 8+ mobile phone with the best performance at present.
First, preface: What is the difference between the first generation Snapdragon 8+ processor and the Red Devils 7S?
With the release of Qualcomm’s new first-generation Snapdragon 8+ processor, high-end gaming mobile phones have started a comprehensive upgrade. Among many flagship mobile phones with the first generation of Snapdragon 8+ recently released, Red Devil 7S is one of the few models that can lead the industry in heat dissipation and performance.
So what are the advantages of the Red Devils 7S?
1, the first generation of Snapdragon 8+ processor.
The first generation Snapdragon 8+ processor adopts a "1+3+4" three-cluster architecture, which consists of one super-large core Cortex X2, three large cores Cortex A710 and four Cortex A510.
From the architecture point of view, it is no different from Snapdragon 8 gen 1 processor, and its hint mainly lies in the frequency. Among them, Cortex X2 frequency has increased from 3.0GHz to 3.2GHz, Cortex A710 core frequency has increased from 2.5GHz to 2.75GHz, and Cortex A510 has also increased from 1.8GHz to 2.0GHz.
Due to the frequency increase, the overall performance of the first generation Snapdragon 8+ processor has been improved by 10%, and the energy efficiency ratio has also been improved by 30% due to the switch to TSMC 4nm process.
2. ICE magic cooling system with 20,000 rpm fan
The Red Devils installed a layer of graphene copper foil, and the thermal conductivity medium was aerospace-grade graphene composite phase change material. When the temperature of the CPU was higher than 40 degrees, the phase change occurred, and the heat emitted by the core CPU was quickly absorbed. The thermal conductivity was increased from 0.3W/mk to 120W/mk, which was 400 times higher, and the heat of the CPU could be quickly absorbed.
The mobile phone also has a built-in high-speed centrifugal fan with a speed of up to 20,000 rpm, which can quickly discharge the internal temperature of the fuselage. The speed of the fan can be adjusted manually or by itself according to the CPU temperature.

Genshin Impact has been around for more than two years, and it is still a killer of mobile phone hardware.
Select "extremely high image quality" and adjust the upper frame rate to 60FPS.
In balanced mode, you can easily fill the frame.
We ran randomly for 15 minutes, except for the frame rate fluctuation during transmission, which was basically stable at 60FPS during normal play and the average frame rate was stable at 59.55FPS.
2. Peace elite
"Peace Elite" was locked at 60FPS, and we tested it in HDR HD mode.
In the energy-saving mode, it is easy to reach 60FPS.
We played for 30 minutes, and looked at AIDA64 and found that the highest temperature of the processor was only 39 degrees.
3. the glory of the king
Screen settings: extremely high frame rate, ultra-high resolution, high-definition image quality and anti-aliasing.
In energy-saving mode, the frame rate will be locked at 60FPS, and in equalization mode, the frame rate will be stable at 120FPS.
Even if the highest picture quality is 120FPS, the frequency of Adreno 730 GPU is only 220MHz, and its highest frequency can be as high as 800MHz.
Today, the glory of the king is only a small game for the first generation of Snapdragon 8+ processors.

When testing, turn on 50% brightness, turn off the volume, and use the battery dog APP to continuously run 3D games, videos, web browsing and other scenes to test battery life.
First, the test was carried out at 165Hz, and the power failure was 11% for 1 hour and 34% for 3 hours. According to this calculation, if the battery is fully charged until it runs out, it should last for about 9 hours.
Adjust the refresh rate back to 60Hz, power off 8% for 1 hour, and it should last for 11~12 hours if it is fully charged.
3. Genshin Impact Power Consumption Test
The picture quality is set to "extremely high", the frame rate is 60FPS, and the refresh rate is 165Hz.
The initial power is 20%, and the mobile phone is set to "balanced mode".
When the power dropped from 20% to 5%, the time passed by 28 minutes, so it is estimated that the Red Devils 7S can last for 3 hours in the fully charged state.
Summary: Snapdragon 8+ mobile phone with the best performance at present.
We have tested a number of mobile phones equipped with the first-generation Snapdragon 8+ processor, and the Red Devils 7S is the most powerful one.
Take Antu Bunny as an example, the first generation of Snapdragon 8+ processor mobile phones are basically between 1.06 million and 110 W,The Red Devils’ 7S running score soared to 1.126 million, which is the highest running score we have got so far.
The same is true of GFXBench, a test program that consumes extremely GPU, which will lead to the processor’s high temperature and frequency reduction in the later stage of the test. Other first-generation Snapdragon 8+ mobile phones achieved a score of around 440FPS in the "1080P Tyrannosaurus Rex Off-screen" project, while the Red Devils 7S ran to 458FPS, leading by nearly 5%. After installing the cooling back clip, the frame rate is further improved to 471FPS.
In addition to the exclusive adjustment, the Red Devils 7S can achieve such results.ICE magic cooling system also contributed.
A high-speed centrifugal fan with a rotation speed of up to 20,000 rpm, on this basis, an ultra-soft and high thermal conductivity rare earth, an aerospace-grade graphene phase change material with a thermal conductivity of 120W/mk, and a layer of graphene copper foil are added. With so many latest cooling technologies, the Red Devils 7S can easily handle the first-generation Snapdragon 8+ processor with excellent energy efficiency ratio.
It can charge 20% in 2 minutes, and it takes 21 minutes to fully charge the 4500mAh battery.
In terms of battery life, if the screen is turned on with a refresh rate of 165Hz, the battery dog actually measures 9 hours of battery life. At 60Hz refresh rate, the battery life has increased to nearly 12 hours.Running the Genshin Impact at 165Hz high brush can last for 3 hours at full charge.
As for heating, the power consumption of the first generation Snapdragon 8+ processor has been improved by 30% after switching to MediaTek 4nm process technology. For games like Peace Elite and the glory of the king, the 7S fuselage of the Red Devils will not generate heat basically, which is similar to the hand temperature. If you play Genshin Impact for a long time, the temperature of your mobile phone may be around 43 degrees. Adding a heat dissipation back clip can effectively reduce the temperature.
Although the Red Devils 7S is a mobile phone that focuses on e-sports and games, its performance in taking pictures is still remarkable. The 64-megapixel main camera+8 million super wide-angle lens+2 million macro lens is a three-camera module, which can meet the needs of daily photography.
For heavy mobile gamers, the pursuit is naturally the ultimate mobile gaming experience.At present, the game mobile phone that can optimize the performance and temperature of Snapdragon 8+ to the best state is the Red Devils 7S.
