MediaTek recently announced a new addition to its line of Dimensity smartphone chips with the new 9400+, which builds on the already-impressive capabilities of the Dimensity 9400 from a while back. MediaTek claims that the new chip comes with a more power-efficient design, as well as support for new AI-based software features and large language models (LLMs). What else can we expect from it though? Let’s take a look.

At the risk of getting “nerdy” for a second, here’s what the new chip comes with—the Dimensity 9400+ is developed with an All Big Core design which includes a single Arm Cortex-X925 core that can run at up to 3.73GHz. This is accompanied by a trio of Cortex-X4 and 4x Cortex-A720 cores, a configuration that on paper can improve single and multithreaded performance for Android devices. Speaking of the latter, MediaTek adds that we’ll see new phones powered by the 9400+ within this month.
Inside you’ll find MediaTek’s NPU (neural processing unit) 890, which allows the the Dimensity 9400+ to process LLM capabilities and faster reasoning with features like Mixture-of-Experts (MoE), Multi-Head Latent Attention (MLA), Multi-Token Prediction (MTP), and FP8 inferencing. This also allows the chip to run agentic AI tasks with as much as a 20% boost when it comes to Speculative Decoding+ (SpD+). There’s also ab integrated Dimensity Agentic AI Engine (DAE) that can “transform” conventional AI applications into agentic AI apps.
Unsurprisingly, the 9400+ is also designed for more powerful mobile processing and gaming experiences—it comes with a 12-core Arm Immortalis-G925 GPU that allows the chip to run features like opacity micromap (OMM) support, which can render graphical elements and effects with better efficiency. The built-in GPU is also designed for sustained peak gameplay speeds even during extended gaming sessions; the 9400+ also includes a new frame rate converter 2.0+ which according to MediaTek can double FPS and improve power efficiency by up to 40% when active.

For photography, the chip is equipped with MediaTek Imagiq 1090 for HDR video across zoom ranges and Smooth Zoom for seamless moving subject capture with selective image and audio isolation. Additionally, the 9400+ also expands phone-to-phone Bluetooth range to 10km, offers faster BeiDou satellite connection TTFF, supports Wi-Fi 7 tri-band concurrency with five streams and extended Wi-Fi coverage via MediaTek Xtra RangeTM 3.0, and provides flexible 5G/4G Dual SIM Dual Active, Dual Data capabilities.
