Oppo says its MariSilicon X chip processes images better than Apple’s A15 and Snapdragon 811
You might also think that the 18-bit image signal processor embedded in Qualcomm’s new 8th-generation Snapdragon chip, which will be used in most of next year’s flagship smartphones, will perform very well. ; But Oppo has also taken measures in this field, the result of which we will see in the next flagship phones of this company and probably OnePlus phones; Because Oppo and OnePlus merged with each other some time ago.
According to PhoneArena, Oppo has probably developed a dedicated chip inspired by Samsung’s exclusive Exynos chips or Google’s Tensor. Apparently, this company, like many big brands active in the field of smartphones, is trying to save some of the initial costs of making new products by making the processors they need. MariSilicon X)
In making the MariSilicon X chip, Oppo focuses on image processing and artificial intelligence calculations. This company has managed to produce a neural processing unit with the power to perform 18 trillion calculations per second, which is considered the best option in its class in terms of energy consumption, because the image signal processing unit (ISP) is produced on a cost-effective 6nm process. For comparison, the neural engine in the Apple A15 chip used in iPhone 13 phones offers the possibility of performing 15.8 trillion operations per second.
Another attractive feature of MariSilicon X is the processing of Ultra HDR images. Oppo offers the possibility of 20-bit 4K HDR video recording with a contrast ratio of 1,000,000:1, which, according to the Chinese, is at the level of the dynamic range of the human eye. Oppo describes the ISP used in the MariSilicon X chip as follows:
Opo has designed a unique ISP based on trends it sees in online videos and user-generated videos. The ISP of this chip can combine multiple HDR frames directly in the RAW domain and offers the possibility of recording 4K Ultra HDR videos with an incredible dynamic range of 20 bits and 120 dB. Such videos offer a contrast ratio of 1,000,000:1 between the lightest and darkest parts of the image, and in this sense, they perform at the level of the human eye. For comparison, the OPPO Find X3 Pro phone, which uses the Snapdragon 888 processor, provides the possibility of recording videos with a dynamic range of 18 bits or 108 dB, thus the dynamic range of the MariSilicon X will be four times that.

Opo’s RAW image processing unit performs better than Qualcomm’s 8th generation Snapdragon and Apple’s A15, at least in terms of numbers. In this context, Oppo refers to phones under its own brand as well as OnePlus phones; For example, the Chinese have developed an RGBW sensor and use MariSilicon’s proprietary algorithm to process imaging data from an unusual pixel arrangement. Apply RAW Super Sampling twice to separately process RGB and W signals. RGB + W images have 8.6 dB higher signal-to-noise ratio and 1.7 times more textures. As a result, the recorded content, whether in the form of photos or videos, will be more prominent.

By adding a yellow pixel to its sensors, Huawei increased the sensitivity of the camera of its products to light, but this action faced problems in color display; So it’s good to see that Oppo has used the extra white pixel in its proprietary ISP. MariSilicon X is considered to be the first chip that can process raw image data live.
Phones that will be launched with the MariSilicon X chip in the future will provide the user with the possibility of instant preview of HDR photos and videos. gave This feature will provide the user with a real experience that what he sees in the image is exactly what will be recorded as a photo or video. In this way, the mentioned feature will provide people with the necessary capacities to create new creations.
It is said that Oppo Fide X4 Pro will be among the first smartphones that will use the MarySilicon X chip; Of course, some OnePlus phones may also use this chip, including the OnePlus 10 series. According to recent rumors and reports, the OnePlus 10 series will probably be officially introduced next month.
