Specialized image chips can significantly boost camera performance, and OPPO’s next flagship series will follow suit. OPPO has designed its own silicon to handle image processing, the company announced at its third-annual Inno Day innovation event. Plus, it appears in the next Find X series, probably called the Find X4. OPPO’s latest in-house chip, dubbed MariSilicon X, is based on a 6nm process and combines a sophisticated NPU, ISP, and multi-tier memory architecture into a single chip.

The physical constraints in smartphones limit how much camera hardware can be improved; there’s only so much room for a larger sensor or longer zoom lens. However, “ software algorithm offers unlimited possibilities; and this is why OPPO developed the MariSilicon X,” according to OPPO’s senior director of imaging Bo Jiang.

Essentially, this provides OPPO more control over the image processing pipeline. It will help the company in everything from taking image data to processing it to the end result; a photo or video that has undergone a variety of digital processing. According to OPPO’s Jiang, the MariSilicon X focuses on processing photos from the RAW domain. It contains a lot more data, but processing this data required computing power that earlier Snapdragon ISPs couldn’t handle. OPPO showed off samples of images and videos produced by a MariSilicon X smartphone. Plus, the Find X3 Pro in tough settings, and the chipset samples appeared definitely superior.
The MariSilicon X’s NPU, according to OPPO, can do 18 trillion operations per second and has a dedicated memory bandwidth of up to 8.5GB/s. As dedicated memory avoids needless read-write cycles, the MariSilicon X is more energy efficient. The ISP also supports 20bit picture capture, which gives it a 4x higher dynamic range than the Find X3 Pro’s ISP.
