Highlights: Redmi K40 Gaming Edition Teardown and Dimensity 1200 Performance Overview
Redmi K40 Gaming Edition Teardown
Redmi K40 Gaming Edition is a new member of the Redmi K40 series that officially debuted on April 27, which features a 6.67-inch flexible OLED screen with a refresh rate of 120Hz, encapsulating the MediaTek Dimensity 1200 flagship processor, 64MP AI triple camera on the rear, 5065mAh battery and 67W flash charging in a limited space, while bringing the Black Shark phone’s mechanical shoulder keys. Recently, the official shared Redmi K40 Gaming Edition teardown video clearly shows off the internals of the device.
The first thing you see is the hexagonal boron nitride aerospace-grade cooling material, specifically located on the back of the rear cover and right next to the motherboard. As you can see from the teardown diagram, the Redmi K40 Gaming Edition is also stuffed with NFC coil components, infrared emitters, and most of the phone’s screws have been spot-glued.
After the main board and camera bezel were removed, the rear 64MP main camera + 8MP super wide-angle camera + 2MP macro camera was shown in front of the eyes. The 64-megapixel main camera also uses ED ultra-low dispersion optical glass lens with a plastic lens.
The shield is uncovered, this is the LPDDR4X memory and UFS 3.1 flash memory particles, as for the Dimensity 1200 is located below the memory, here can not be directly observed.
The middle of the phone’s shell directly opposite the processor is covered with a large area of VC even thermal plate, and also coated with silicone grease to help conduct heat and promote continuous fully-optimized gaming performance.
From the disassembly, we also found that the battery of the disassembled Redmi K40 Gaming Edition is manufactured by Dongguan New Energy Technology Co. (also known as ATL), code-named BM56, with a typical capacity of 5065mAh and a rated capacity of 4965mAh.
It is worth mentioning that we also got the first glimpse of the Redmi K40 Gaming Edition magnetic power shoulder button – in terms of mechanical structure, it adopts the feature of magnets repelling each other with the same pole and attracting each other with different poles to create a super miniature magnetic power shoulder button through the shoulder key switch.
When it is closed, the magnets are attracted to each other to prevent the keys from shaking; when it is opened, the magnets are repelled by each other, and when it is fully opened, the magnets of the shoulder keys and the drive bar are again attracted to each other.
Redmi K40 Gaming Edition Performance: High-powered game engine Dimensity 1200 performance test.
In 2021, cell phone processors have evolved along two very distinct technical lines: “extreme performance at any cost” and “excellent balance of performance and power consumption”. Among them, the Dimensity 1200 is the representative of the ultimate balanced.
Industry first-tier flagship processor:
The Dimensity 1200 uses TSMC’s 6nm process, which is one of the most advanced cell phone SoC manufacturing processes available. Compared to Samsung’s 7nm process, the same power consumption performance is stronger, the same performance power consumption is lower, and the power consumption performance under long-time games is better.
Secondly, Dimensity 1200 is equipped with a high energy efficiency ratio A78 core, the main frequency up to 3.0GHz. and 1 + 3 + 4 flagship architecture. The game when the eight cores running at full power, and when not needed, the cores are properly turned off to reduce power consumption. The overall performance is 22% higher than the previous generation, and energy efficiency is 25% higher.
In addition, the Dimensity 1200 also uses an integrated 5G baseband, which not only supports NSA+SA 5G dual-mode, but also supports 5G+5G dual SIM dual standby, and the latest upgrade of the caller’s continuous network 3.0, with the most complete 5G communication experience.
Four months of joint tuning to unleash the full potential of the hardware:
The new Game Turbo 5.0, which supports independent GPU driver upgrades and GPU Tuner, allows Redmi and MediaTek to give the most appropriate graphics parameters to different players and games, giving full play to the phone’s hardware performance. It really allows the phone to have PC-level graphics parameter settings so that every player can find their own exclusive custom gaming experience.
Theoretical performance test, running score easily exceeds 710,000:
The theoretical performance test was conducted using AnTuTu Benchmark, version V9.0.5-OB, and the K40 Gaming Edition scored over 710,000 points in all three tests. In the current cell phone processor performance ranking, it is undoubtedly in the first echelon. Whether it is for daily use or large games, it provides a smooth and stable experience with performance on demand.
Game test, high frame game stable full run:
The game “Peace Elite” is a large shooting game that we are all very familiar with, with fierce confrontation and strong competition, using the game for real testing. After entering the game, the frame rate was adjusted to 90 fps in the screen settings, which is currently the highest frame rate that can be turned on in Peace Elite (Chinese version of PUBG).
The K40 Gaming Edition has pop-up physical shoulder keys with quick response and realistic feedback, which is perfect for shooters like Peace Elite and can greatly enhance the in-game control experience. Slide-out the Game Turbo shortcut menu to set the game shoulder buttons. Here, we set the L button to fire and the R button to fire the scope. This makes it easy to be able to shoot and fire the scope on the move.
During the 30 minutes of gameplay, the K40 Gaming Edition maintained a smooth and stable performance output throughout. The average frame rate reached 89 fps, close to the full-frame rate, and the overall frame rate performance was smooth, with no significant frame drops. For medium and heavy gamers, it provides a sufficient performance guarantee for long and enjoyable games.
The Redmi K40 Gaming Edition is positioned as a “gaming workhorse”, and in addition to a fully upgraded gaming experience, it also places more importance on long-term stable performance output.
This is a brand new species. Through the test, as the game engine of Dimensity 1200 for K40 Gaming Edition provides sufficient performance guarantee, to deal with the mainstream large games without pressure, with the use of shoulder keys, the gaming experience is more enjoyable.
