After being in the rumor mill for a while as the M1 processor (not related to Apple’s in-house M1 chips), OPPO announced its first in-house silicon with the MariSilicon X NPU. Made using a 6nm process, the main goal of the MariSilicon X is to improve the quality of photos and videos in terms of post-processing.

While it is an NPU, the MariSilicon X has its own ISP, so phones equipped with this NPU will not need to depend on ISPs found on mobile processors.  Key features of the MariSilicon X include support for up to 20-bit, 120db dymanic range in images, real-time RAW processing with 4K videos, and an AI algorithm that can apply noise reduction, color reproduction fixes, HDR, and more to images and videos when needed.

The MariSilicon X’s ISP can fully harness OPPO’s RGBW sensors, along with being able to shoot 4K HDR video and feature a dedicated night mode for shooting 4K video. On the NPU side, the MariSilicon X cxan do up to 18 trillion operations per second (TOPS), and keeps its efficiency with a dedicated memory system that can do data transfers of up to 8.5GB/s.

As it was announced at INNO Day 2021, the MariSilicon X will be available with the next OPPO Find X series phone next year.
