In 2020, Black Shark 2 introduced the concept of "independent display" for the first time in the mobile phone field (mainly used for DC dimming), and it was carried forward by the iQOO Neo 5 launched in 2021 (mainly focused on game frame insertion). Nowadays, more and more people Mid-to-high-end mobile phones are beginning to be equipped with various "independent display chips".

In fact, the so-called "independent graphics" used by mobile phone manufacturers come from the Pixelworks series of visual processors owned by Zhuidian Semiconductor Co., Ltd.

Pixelworks's visual processors include Pixelworks i3 (formerly Iris 3), Pixelworks i6, Pixelworks X5 (formerly Iris 5) and X5 Pro, and their positioning has been improved in turn. The most powerful Pixelworks X5 series features MotionEngine technology, which can achieve game frame insertion capabilities. Mobile phones such as iQOO Neo 5, iQOO Neo5S, iQOO Neo6, iQOO 9 Pro and realme GT Neo3 are all its customers.

With the help of Pixelworks X5 series visual processors, mobile phones can achieve two major functions at the system level: "increase frame rate " and "optimize power consumption". Among them, "increased frame rate" can allow games that do not originally support 120FPS to achieve 120FPS display. For example, when playing " Genshin Impact " on a mobile phone, it can only run in 60FPS mode by default. However, after turning on this function, the game can be converted to 120FPS by inserting frames (the actual calculation amount of the GPU is still 60FPS), thus further improving smoothness. Compared with hardware rendering 120FPS, the power consumption is almost negligible.

"Optimize power consumption" forces the current game to run at a locked frame of 45FPS, and then inserts frames through Pixelworks X5 to display at 90FPS. Equivalent to the fact that the GPU only needs to render 45FPS resources to output a smooth picture of 90FPS, thus significantly reducing power consumption and heat generation during the game.

Unfortunately, the Pixelworks X5 series visual processor will cause a high delay when inserting frames in the game, causing the game screen and operations to occasionally "not follow the player", making the game awkward to play.

The good news is that with the commercial mass production of the new Pixelworks X7 visual processor of Zhuidian Semiconductor Co., Ltd., the contradiction between frame insertion and delay seems to have been resolved.

html On July 12, realme GT2 Master Discovery Edition was officially released. In addition to being equipped with Qualcomm Snapdragon 8+ processor, this phone also has the world's first Pixelworks X7.

Judging from the official press release of Zhuidian Semiconductor Co., Ltd., the Pixelworks X7 visual processor has upgraded the MotionEngine technology, which can achieve 2x, 3x, and 4x game frame insertion, and can significantly reduce latency. The introduction of low-power super-resolution technology allows low-definition games to have a high-definition experience beyond native resolution. It supports the low-power AI display inference function that was originally only supported by Pixelworks i6, so that every frame can present optimal HDR image quality in any lighting environment, etc.

There are many mobile phones on the market equipped with Pixelworks X5 series visual processors, but they only support 2x game frame interpolation, that is, 30FPS frame interpolation at 60FPS, 45FPS frame interpolation at 90FPS, or 60FPS frame interpolation at 120FPS. With the help of Pixelworks X7, the Realme GT2 Master Exploration Edition can bring "multiple frame interpolation technology". It has been adapted to the game "One Piece: Bloodline". In this game, you can see "low power consumption 120 Frame" option, after turning it on, GPU only needs to render a 30FPS picture, and what we see is a 120FPS picture output by Pixelworks X7 four times.

The most important thing is that Pixelworks X7 can reduce the frame insertion delay from 30ms of the previous generation to 10ms, which is almost imperceptible, ensuring the accuracy of game operations. At present, the non-sensory frame insertion mode has been implemented in more than 20 popular mobile games such as " Peace Elite ", " King of Glory ", "Genshin Impact", "QQ Speed ​​​​" and " One Piece Passion ". adaptation.In addition to the above-mentioned games, frame insertion technology is also applied in several popular video APPs. Users can enable related functions in , Tencent Video, , iQiyi Video, Youku Video, and Bilibili to obtain a silkier and smoother picture quality experience. .

With the help of Pixelworks Resolution expanded to high resolution. This means that we can set the game image quality to low (reduce the GPU load), and then use the game's super-resolution function to improve the image quality with low power consumption, solving the problem of having to have both fish (image quality) and bear's paw (power consumption) in the past. of embarrassment.

In short, up to 4 times the ultra-low latency frame insertion technology and low power consumption super resolution technology are the core selling points of Pixelworks X7 that are different from the previous generation X5. They can all further solve users’ real pain points in the game. Following the Realme GT2 Master Exploration Edition, I believe that more new mobile phones will soon be equipped with this visual processor, and we also hope that these two useful new features can be perfectly adapted to more mainstream games.
