At the core of the Dimensity 9400 is a second-generation All Big Core design, featuring a powerful Arm Cortex-X925 core operating at 3.62 GHz. This architecture boasts a 35% increase in single-threaded performance and a 28% boost in sustained multi-threaded performance compared to its predecessor. The chipset employs TSMC's N3E process technology, reducing power consumption by 40%, resulting in longer battery life and improved energy management during peak loads.

MediaTek is positioning this chipset as a leader in mobile AI with its new Dimensity Agentic AI Engine (DAE). Agentic AI enables devices to autonomously perform goal-oriented tasks, enhancing user interaction through adaptive behavior and decision-making capabilities. The inclusion of an 8th-generation neural processing unit (NPU) allows for a 50% increase in token processing speed, making it ideal for complex applications like on-device video generation.
