Chinese smartphone giant Oppo revealed its first in-house chipset at its annual innovation event hosted in Shenzhen on Tuesday. The MariSilicon X chip announced — named after the Mariana Trench — is a neural processing unit that aims to boost photo and video performance through machine learning.

The move adds Oppo to a list of smartphone makers that are designing their own chips, such as Apple. The MariSilicon project, headed by Qualcomm veteran Jiang Bo, started only in 2019.
