MediaTek Dimensity 9400 chipset launched - Check details

MediaTek has launched the Dimensity 9400, the company’s new flagship smartphone chipset optimized for edge-AI applications, immersive gaming, incredible photography, and more. According to the company, the Dimensity 9400 - the fourth and latest in MediaTek’s flagship mobile SoC lineup - offers a massive boost in performance with its second-generation All Big Core design built on Arm’s v9.2 CPU architecture, combined with the most advanced GPU and NPU for extreme performance in a super power-efficient design.

The Dimensity 9400 adopts 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 per cent faster single-core performance and 28 per cent faster multi-core performance compared to MediaTek’s previous generation flagship chipset, the Dimensity 9300. Built on TSMC’s second-generation 3nm process, the Dimensity 9400 is up to 40 per cent more power-efficient than its predecessor, allowing users to enjoy 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 fueling generative AI technology with on-device LoRA training and video generation,” said Joe Chen, President at MediaTek.
 
The company said that Dimensity 9400 boasts a number of industry firsts for exceptional generative AI performance. "The chipset 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 company said.

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 run 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 first smartphones powered by the MediaTek Dimensity 9400 will be available in the market starting in Q4 of 2024.

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.
