Optimised for edge-AI applications, immersive gaming, and photography, the Dimensity 9400 is the fourth in MediaTek’s flagship mobile SoC lineup.
This SoC offers a significant boost in performance with its second-generation All Big Core design built on Arm’s v9.2 CPU architecture and combined with advanced GPUs and NPUs for extreme performance delivers what the company has described as a ‘super power-efficient’ design.
The Dimensity 9400 has adopted MediaTek’s second gen All Big Core design, integrating one Arm Cortex-X925 core operating over 3.62GHz, combined with 3x Cortex-X4 and 4x Cortex-A720 cores. This design offers 35% faster single-core performance, and 28% faster multi-core performance compared to MediaTek’s Dimensity 9300.
Built on TSMC’s second-generation 3nm process, the Dimensity 9400 is up to 40% more power-efficient than its predecessor, providing much longer battery life.
“The MediaTek Dimensity 9400 will continue furthering our mission to be the enablers of AI, supporting powerful applications that anticipate users’ needs and adapt to their preferences, while also fuelling generative AI technology with on-device LoRA training and video generation,” said Joe Chen, President at MediaTek.
Including MediaTek’s 8th Generation NPU, the Dimensity 9400 provides a number of industry firsts for exceptional generative AI performance. It is the first mobile chipset to offer on-device LoRA training, high-quality on-device video generation, and developer support for Agentic AI.
To allow users to take advantage of the latest agentic and generative AI applications, the Dimensity 9400 offers up to 80% faster large language model (LLM) prompt performance while also being up to 35% more power efficient than the Dimensity 9300.
The Dimensity 9400 also integrates MediaTek’s new Dimensity Agentic AI Engine (DAE), which is designed to turn traditional AI applications into sophisticated agentic AI applications. MediaTek is working with developers to offer a unified interface between AI agents, third-party APKs, and models that efficiently runs both edge AI and cloud services.
This streamlined approach allows models to work with many different third-party APKs, which reduces development time and will help usher in a new ecosystem of agentic AI applications.
The 12-core Arm Immortalis-G925 delivers immersive gaming experiences with up to 40% faster raytracing performance compared to the previous generation.
The Dimensity 9400 also brings PC-level features to smartphones with opacity micromaps (OMM) support for realistic effects. The chipset’s powerful GPU also offers 41% peak performance boost with up to 44% power savings compared to the Dimensity 9300, allowing users to game for longer. Additionally, the Dimensity 9400 supports HyperEngine technology for super resolution and impressive picture quality, which is co-developed by MediaTek and Arm Accurate Super Resolution (Arm ASR).
With MediaTek Imagiq 1090, the Dimensity 9400 also provides HDR video recording throughout the entire zoom range so users can snap the perfect moment from a distance; MediaTek’s Smooth Zoom technology also makes it easy to capture moving subjects.
In addition, it has been designed to minimise power consumption while users are taking photos and videos, offering up to 14% lower power consumption in 4K60 video capture compared to the Dimensity 9300.
Additional features of the Dimensity 9400 include:
- A refreshed 3GPP Release-17 5G modem with 4CC-CA and up to 7Gbps sub-6GHz performance.
- New 4nm Wi-Fi/Bluetooth combo chip with 7.3Gbps data rates performance and up to 50% lower power consumption compared to the previous generation.
- Support for Wi-Fi 7 tri-band MLO.
- MediaTek Xtra RangeTM 3.0, which delivers up to 30m greater Wi-Fi coverage.
- 5G/4G Dual SIM Dual Active, Dual Data capabilities to give users more flexibility.
- Support for tri-fold smartphones giving smartphone makers the flexibility to design innovative new form factors.
The first smartphones powered by the MediaTek Dimensity 9400 will be available in the market starting in Q4 of 2024.
