Mariana x's computing power performance far exceeds Apple A 15, and OPPO executives interpret the mental journey behind it.

Anyone who pays attention to the digital circle should know that with the continuous development of smart phones, the focus of attention on mobile phones has gradually shifted from performance configuration to image shooting in recent years. More importantly, mobile phone images also began to adjust the algorithm by simply adding pixels and cameras, and developed their own chips. For example, Huawei and OPPO, which we are familiar with, are the most typical examples. Recently, Efficotech had an exclusive interview with jiang bo, senior director of OPPO chip products, from which you may get a glimpse of the mental journey of the chip developed by Green Factory.

From this interview, we can see that the reason why OPPO's self-developed chips choose images as the starting point is because images have always been the strength of OPPO and a long-term user value point. On the other hand, it can be commercialized faster, and accumulate experience for OPPO core-making (SOC) in the future. According to jiang bo, senior director of OPPO chip products, when developing Mariana X this time, the cost invested by OPPO was in the order of hundreds of millions of dollars, which shows how much financial and material resources the official spent on this chip.

At the same time, jiang bo also mentioned that the current mobile phone image shooting is good mainly in two aspects: NR (noise reduction) and HDR. Therefore, OPPO also started from these two aspects at the beginning of research and development. Finally, through continuous research and development, Mariana X finally achieved four technological breakthroughs in AI computing energy efficiency, super HDR, real-time RAW computing and RGBW Pro, which not only realized the new standard of computing images, but also was an important milestone on OPPO's self-research road.

For example, in the video of Efficotech, we can see that, thanks to Mariana X's powerful AI computing ability (AI computing per second 18 trillion times), Find X5 Pro equipped with this chip finally makes the picture clearer and brighter, and the color reproduction and noise processing are also better, as can be seen from the real shot. When Find X5 Pro and Find X3 Pro shoot the same picture, it is obvious that the former has more details, brighter picture, less noise and a better overall look.

In addition, Mariana X also integrates OPPO's self-developed and industry-leading MariLumi image processing unit, which supports 20-bit image processing and Ultra HDR super dynamic range. The maximum picture light ratio can reach 65,438+0,000,000: 65,438+0, which is four times that of the current flagship platform HDR. Therefore, in the face of high-magnification light scenes such as dark light and backlight, the details and dynamic range that can be displayed are also better. For example, as mentioned in the video, in the current HDR camera performance, the imaging performance of Find X5 Pro equipped with Mariana X is the closest to iPhone in Android system.

Generally speaking, the arrival of self-developed chips will inevitably enhance the competitiveness of OPPO in high-end products, and the launch of Mariana X will also usher in the new development of OPPO computing photography. In the future, OPPO will, as jiang bo said, continue to develop chips and optimize algorithms, and continue to bring consumers a more practical and excellent image shooting experience. You might as well wait and see.
