As scheduled, Xiaomi's sub brand, Redmi, has just presented its first gaming phone ever; we welcome the Redmi K40 Gaming Edition.

Redmi K40 official Gaming Edition: 120Hz OLED screen and Dimensity 1200 at 1999 yuan (260 €)

Redmi K40 Gaming Edition

Let's start with the design of the smartphone which based on the Redmi K40 Gaming Edition is slimmer and lighter than practically all other gaming phones on the market. In particular, we are talking about a thickness of 8,3 mm and a weight of 205g, which should automatically make it the lightest and thinnest gaming phone of 2021 (if not ever).

Externally the device sees the presence of fifth generation Corning Gorilla Glass both on the screen and on the back cover. Inside the flat-edged metal chassis we have magnetic levitation shoulder buttons that are automatically ejected and retracted after pressing the dedicated buttons. Clearly these come in very handy especially when playing FPS games. Another very interesting precaution used by the brand is to bring a flash module with lightning design even if obviously this does not add any real improvement.

Redmi K40 Gaming Edition

As for the specifications, the Redmi K40 Gaming Edition adopts a 6,67-inch OLED screen, surrounded by 1,8 mm thick side and top edges, while the chin is slightly thicker at 2,7 mm. The display integrates 1,07 billion colors, a high refresh rate of 120Hz and a three-finger touch sampling rate of 480Hz.

The Redmi K40 Gaming Edition is powered by a MediaTek Dimensity 1200 chipset that uses a TSMC 6nm manufacturing process, with 1 + 3 + 4 three cluster architecture and achieves an excellent balance between performance and power consumption (the Antutu score reaches up to 720.000 points).

In particular we have a super-large core that reaches up to 3,0 GHz, which takes care of heavy and complex loads, improving performance by 22% and reducing consumption by 25% compared to the previous generation. The GPU instead sees an improvement of 13% compared to the Dimensity 1000+, so more than excellent for everyday use and for gaming without dropping frames.

In this regard, Redmi claims that this hardware combination has passed TÜV Rheinland's high-performance gaming certification. It can therefore run games like "Honor of Kings" and "Peace Elite" at 90fps without any problems.

While to keep temperatures at bay, the smartphone uses an exclusive heat dissipation technology developed by Redmi. This consists of a 11540mm² aerospace composite heat dissipation surface that instantly drops the temperature by 2 ° C, allowing us to play heavier video games without overheating.

Redmi is not spared even in the audio sector by bringing a JBL stereo system, with a closed structure with a large independent double sound cavity; dual speaker + 3MIC designed for gaming, held horizontally without obstruction; Dolby Atmos + Hi-Res double gold standard, sound quality certification; and the MISOUND algorithm to achieve perfect sound quality.

For photos, the smartphone adopts a 64-megapixel main camera, an 8-megapixel ultra wide-angle camera and a 2-megapixel macro camera. The main camera sensor also supports 4-in-1 pixels, capable of synthesizing 1,4um large pixels in low light conditions, improving the ability to take photos in night scenes.

Finally, the device integrates a 5065mAh battery, which supports 67W fast charging, to recharge the smartphone to 100% in just 42 minutes with the customized charger supplied with L-connector.

The Redmi K40 Gaming Edition will be sold in China in the 6GB + 128GB version at the price of 1999 yuan (255 €), the 8GB + 128GB version at 2199 yuan (280 €), the 8GB + 256GB version at 2399 yuan (305 €), the 12GB + 128GB version at 2399 yuan (305 €) and the 12GB + 256GB version at 2699 yuan (344 €).

I would have preferred the 1100 as a cpu (that's enough and advances, and with slightly lower frequencies consumption and heat are reduced), the 6.81 of the Mi11 as the screen (which is already small to be associated with gaming or multimedia). Good audio (to be checked). Useless and ridiculous physical buttons, then having to use the usual virtual stick with which I can not do anything. If you want to play action games on mobile, connect a BT pad, those with support for mobile phones, and then yes that is right ... (personally I play on mobile, but only... Read the rest » - ​​The Italian community for Xiaomi products
