MediaTek pushes AI limits with new Dimensity 9400+ chipset

Equipped with the advanced MediaTek NPU 890, the Dimensity 9400+ enables faster, smarter AI experiences by supporting global LLMs and boosting agentic AI performance by 20% using Speculative Decoding+

MediaTek has expanded its Dimensity flagship chipset family with the Dimensity 9400+ SoC, which provides exceptional generative and agentic AI capabilities as well as other performance enhancements. The Dimensity 9400+ supports the latest Large Language Models (LLM) while sustaining a super power-efficient design.

The Dimensity 9400+ features an All Big Core design, integrating one Arm Cortex-X925 core operating up to 3.73GHz, combined with 3x Cortex-X4 and 4x Cortex-A720 cores. This powerful configuration accelerates single and multithreaded performance for top-tier Android UX experiences.

“The MediaTek Dimensity 9400+ will make it easier to deliver innovative, personalized AI experiences on-device, combined with enhanced overall performance to ensure your device can handle all tasks with ease,” said JC Hsu, Corporate Senior Vice President at MediaTek. “We are working closely with developers and manufacturers to continue building a robust ecosystem of AI applications and other features that will bring a number of speed and privacy benefits to consumers.”

Equipped with the MediaTek NPU 890, the Dimensity 9400+ supports a wide range of LLMs across many regions around the world. The chipset supports Mixture-of-Experts (MoE), Multi-Head Latent Attention (MLA), Multi-Token Prediction (MTP), and FP8 inferencing with faster reasoning speeds. It also offers 20% faster agentic AI performance with Speculative Decoding+ (SpD+). Additionally, the built-in Dimensity Agentic AI Engine (DAE) makes it easy for developers to turn traditional AI applications into sophisticated agentic AI applications.

PC-class graphics on smartphones

The Dimensity 9400+ integrates a 12-core Arm Immortalis-G925 GPU, which enhances gaming visual experiences by bringing PC-level features to smartphones with opacity micromap (OMM) support for realistic effects. This makes video game elements—such as vegetation, hair or feathers—look more realistic and dimensional without impacting performance.

The chipset’s powerful GPU also sustains peak gameplay speeds, allowing users to game longer without lag. Additionally, the Dimensity 9400+ includes a new frame rate converter 2.0+ (MFRC 2.0+), which was developed in coordination with game developers to double effective FPS and enhances power efficiency by up to 40% when MFRC is utilized.

The MediaTek Imagiq 1090 enables HDR video recording across the entire zoom range, allowing users to capture the perfect shot from long distances. MediaTek’s Smooth Zoom technology provides seamless capture of moving subjects while allowing users to isolate the image and audio they want in each scene.

The additional features of the Dimensity 9400+ include ultra-long-range phone-to-phone Bluetooth connectivity of up to 10km (6.6 times farther than the Dimensity 9400), support for BeiDou satellite positioning with 33% faster Time to First Fix (TTFF) even without cellular connectivity, Wi-Fi 7 tri-band concurrency with five streams, MediaTek Xtra Range 3.0 delivering up to 30 meters of extended Wi-Fi coverage, and 5G/4G Dual SIM Dual Active with Dual Data support for greater flexibility and always-on connectivity.
