Mobile phone "double core" has gradually become a trend The second core unlocks a differentiated experience

In the PC field, "single-chip performance is not enough, multi-core to make up" has become a conventional idea to solve the performance bottleneck. Nowadays, smart phones have also begun to enter the "dual core" era from the original "single core", and the high-end flagship series launched by mobile phone manufacturers in the first half of the year are almost all equipped with a "double core" combination, which can not only improve the overall hardware performance, but also bring a differentiated and personalized experience.

OPPO and vivo are the first mobile phone manufacturers to launch the "dual core" strategy. OPPO Find X5 series is the first two-core model launched by OPPO, in addition to the Qualcomm Snapdragon mobile platform, it is also equipped with a self-developed image dedicated NPU chip - Mariana MariSilicon X; Vivo's newly released flagship new X80 series, using a combination of Tianji 9000 and V1+ chips.

In addition to OPPO and vivo, most of the models on sale under iQOO are also equipped with two chips, and Realme's latest model GT Neo3 is also equipped with Tianji 8100+ independent display chips. In addition, the OnePlus Ace is also equipped with a game display chip.

Why is the two-core combination a new favorite?

After several rounds of explosive development of intelligence, the potential that mobile phones can tap on hardware is moving towards a bottleneck, mobile phone manufacturers have been unable to improve the user's experience by stacking hardware, and as the soC chip as the core of the hardware, its performance directly determines the comprehensive performance of the mobile phone in games, shooting and other scenes, but the same SoC chip is difficult to bring a differentiated experience. Therefore, by adding an auxiliary chip, you can not only obtain performance advantages on hardware, but also create a differentiated and innovative experience.

Taking isaps chips as an example, ISP chips are integrated in the processors of mobile phones, and processors like Qualcomm and MediaTek are integrated with ISP chips. The use of processor-supporting integrated ISP chips, the advantage is to reduce the development and production costs of mobile phones, the disadvantage is that the imaging quality may not be as good as independent ISP chips, while the large-scale use of the same processor in mobile phone products means that the same ISP solution, the space for tuning is not very large, resulting in serious homogenization.

In contrast, the use of self-developed ISP chips means that mobile phone manufacturers have more room to play, can fully integrate their own camera debugging algorithms into it, achieve richer scene optimization, provide better performance and effects than the ISP that Comes with SoC, improve the differentiation of mobile phone imaging capabilities, and provide users with richer and better products.

The second chip is played in a variety of ways

It can be seen that around the second chip, mobile phone manufacturers in the image, game and other scenes of the application of continuous innovation, of which the innovation in imaging is particularly prominent, in order to bring users a differentiated image experience, mobile phone manufacturers began to seek a breakthrough in the underlying ISP chip.

Vivo's flagship X80 series adopts the dual-core combination of self-developed chip V1+ and Tianji 9000, and this independent chip gives the image a lot of room to play. Under the blessing of self-developed chip V1+, vivo X80 series can realize the low-light mobile phone "night vision", through the algorithm real-time accurate noise reduction, improve the purity of the night scene, in the extremely dim scene, can also take photos beyond the brightness of the human eye, rich details. In terms of shooting video, it can also play a role in brightening the video, reducing noise and other functions, and improve the quality of the video in low light.

In addition to empowering the image, the V1+ chip will also play a functional role in the game scene, through the AI computing power of the MediaTek APU, the collaborative work of multiple internal and external processors, and the GPU to complete the game's screen rendering, thereby releasing part of the GPU load. At the same time, by calling the hardware and interpolation algorithm of the self-developed chip V1+, the stability of the frame rate is optimized, and the performance and power balance effect are finally achieved.

OPPO Find X5 series is equipped with the self-developed Mariana MariSilicon X image chip, using TSMC 6nm advanced process manufacturing, with strong performance, low power consumption and other characteristics, the ultra-clear night scene video resolution increased by 4 times, lift the night video 1080P picture quality limit, while each frame of the picture is pixel-level AI noise reduction processing, to achieve clear picture quality of night dynamics, and Mariana X will be the traditional processing in the back end, front of the RAW domain.

In addition, some mobile phones that specialize in esports games also enhance the gaming experience through dual-core combinations. The recently launched iQOO Neo6 uses an independent display chip Pro + Snapdragon 8 dual-core combination, through the independent display chip Pro, with EMMC interpolation technology, thereby increasing the number of game frames, mobile phone SoC only needs to render 60 frames natively, through the independent display chip can be inserted to 120 frames, effectively improve the smoothness of the game screen.

It can be seen that the dual-core combination has gradually become a trend on flagship mobile phones, further enhancing the comprehensive experience of the two major application scenarios of imaging and games. By combining with the SoC main chip, you can not only obtain performance advantages on hardware, but also create a differentiated and innovative experience.

At present, the investment of head mobile phone manufacturers in self-developed chips is still increasing. In the research and development of v1+ chips, vivo and MediaTek have invested in an elite development team of more than 300 people, which has become a specific landing of vivo chip strategy. In the 2022 campus and social recruitment plan, OPPO plans to recruit more than 2,000 more people for technology research and development positions to create an engineer's paradise.

Self-developed chips have become a new track for manufacturers to compete, and it also means that "dual-core" mobile phones will enter the track of rapid development, which is worth looking forward to!
