| Overview of the MediaTek Dimensity 9400 mobile processor and its capabilities |
Advanced Architecture and Performance Gains
Built on TSMC's 3nm process node, the Dimensity 9400 promises up to 40% better power efficiency compared to its predecessor. The CPU configuration maintains MediaTek's All Big Core Design approach, featuring:
- 1x Arm Cortex-X925 prime core @ 3.62 GHz
- 3x Arm Cortex-X4 cores @ 3.3 GHz
- 4x Arm Cortex-A720 cores @ 2.4 GHz
This setup reportedly delivers 35% faster single-core and 28% faster multi-core performance over the Dimensity 9300. The new 12-core Immortalis-G925 GPU also brings substantial improvements, with 41% faster peak performance, 40% faster ray tracing, and 44% better power efficiency.
AI Capabilities Take Center Stage
Perhaps the most notable advancements come in the realm of artificial intelligence. The Dimensity 9400 introduces MediaTek's new Agentic AI Engine, a framework designed to standardize AI applications and enable more autonomous AI assistants. Key AI features include:
- Support for Google's Gemini Nano with multimodality
- On-device LoRA (Low-Rank Adaptation) training for LLMs
- 80% faster LLM prompt performance
- Improved on-device video generation capabilities
These enhancements position the Dimensity 9400 as a strong competitor in the rapidly evolving landscape of on-device AI processing.

Cutting-Edge Multimedia Support
The new chip doesn't skimp on multimedia capabilities either. It's reportedly the first mobile SoC to support 8K video capture at 60fps, though thermal constraints may limit real-world implementation. Other notable features include:
- HDR photo and video capture across all zoom ranges
- Support for WQHD+ displays at 180Hz refresh rates
- 24-bit/384kHz Bluetooth audio
- AI-powered noise cancellation for audio recording
Looking Ahead: Tri-Fold and Beyond
In a forward-looking move, MediaTek has built in explicit support for tri-fold devices through a tri-port MIPI interface. While the market for such devices is still nascent, this positions the Dimensity 9400 to power innovative form factors as they emerge.
Market Impact and Availability
The first phones featuring the Dimensity 9400 are set to launch imminently, with Vivo's X200 series expected on October 14th and OPPO's Find X8 lineup following shortly after. While initial releases will likely be limited to the Chinese market, global availability is anticipated by the end of the year.
As MediaTek continues to gain market share in the premium segment, the Dimensity 9400 represents a significant challenge to Qualcomm's dominance. With Samsung already adopting MediaTek chips in some high-end tablets, 2025 could see more flagship Android devices powered by MediaTek silicon.
The smartphone chip landscape is becoming increasingly competitive, and consumers stand to benefit from the resulting innovations in performance, efficiency, and AI capabilities. As always, real-world testing will be crucial to determine how the Dimensity 9400 stacks up against its rivals in practice.
