MediaTek's New Dimensity 9400+: A Game Changer in Mobile Technology

In today's fast-paced tech landscape, innovations in AI and mobile performance are essential. MediaTek has taken a significant step forward by introducing its latest system-on-chip (SoC), the Dimensity 9400+, designed to enhance both generative and agentic AI capabilities. Announced on April 10, 2025, this new SoC promises not only remarkable performance but also exceptional energy efficiency, catering to the demands of today's mobile users.

Technical Specs and Features

The Dimensity 9400+ boasts a unique All Big Core architecture, integrating an Arm Cortex-X925 core clocking in at an impressive 3.73GHz alongside three Cortex-X4 and four Cortex-A720 cores. This configuration significantly accelerates both single-threaded and multi-threaded performance, which is essential for an optimal user experience on Android devices. The aim is clear: to facilitate innovative and personalized AI experiences right on the device, while ensuring that all tasks are processed seamlessly.

JC Hsu, Corporate Senior Vice President at MediaTek, emphasized that this advancement will help developers create robust applications that leverage AI for an improved user experience. The chipset’s embedded MediaTek NPU 890 supports a variety of Large Language Models (LLMs), making it compatible with a wide range of applications worldwide.

Enhancements in AI Performance

One of the standout features of the Dimensity 9400+ is its support for techniques like Mixture-of-Experts (MoE), Multi-Head Latent Attention (MLA), and Multi-Token Prediction (MTP). These enhancements result in faster reasoning speeds and a 20% increase in agentic AI performance, thanks to the Speculative Decoding+ (SpD+) feature. Furthermore, the chipset also includes the Dimensity Agentic AI Engine (DAE), which simplifies the process for developers transitioning conventional AI applications into more sophisticated agentic AI systems.

Gaming and Visual Capabilities

Integrating a powerful 12-core Arm Immortalis-G925 GPU, the Dimensity 9400+ elevates gaming to new heights. It introduces features that bring PC-level graphics quality to smartphones, including support for opacity micromap (OMM) which enhances the realism of game visuals, from dynamic environments featuring lush vegetation to intricate character details such as hair and feathers. The GPU sustains high frame rates, ensuring gamers can enjoy prolonged sessions without lag, making mobile gaming more immersive.

Additionally, MediaTek has developed frame rate converter 2.0+ (MFRC 2.0+), which effectively doubles the frames per second (FPS) during gameplay while enhancing energy efficiency by up to 40%.

Innovative Camera Features

For photography enthusiasts, the new MediaTek Imagiq 1090 provides HDR video capture throughout its entire zoom range, ensuring that every shot is perfectly detailed, even from afar. Coupled with MediaTek's Smooth Zoom technology, it allows users to easily track moving subjects while isolating the desired image and audio elements for superior clarity.

Connectivity and Additional Features

Not only is the Dimensity 9400+ exceptional in processing power and performance, but it also expands Bluetooth connectivity options, increasing the range up to 10 km, a significant improvement of 6.6 times over its predecessor, the Dimensity 9400. It supports BeiDou satellite connectivity for quicker fixes even in areas devoid of cellular service.

Moreover, the chipset features Wi-Fi 7 tri-band capabilities that lead to seamless online connectivity through five streams, supported by MediaTek Xtra Range™ 3.0, which enhances Wi-Fi coverage by 30m.

With functionalities like 5G/4G Dual SIM Dual Active and Dual Data, users can enjoy greater connectivity flexibility. The first smartphones featuring the Dimensity 9400+ will be hitting the market this month.

Conclusion

The media event surrounding the release of the Dimensity 9400+ reflects MediaTek's commitment to providing cutting-edge technology in mobile devices. As the landscape of mobile computing continues to evolve, this SoC is poised to play a pivotal role in how AI applications are integrated into consumer technology, enhancing user experience and offering advanced capabilities that redefine expectations.
