MediaTek Dimensity 9400+ Launched With Focused Upgrades in Gaming, AI, and Connectivity

MediaTek’s new Dimensity 9400+ chipset is now official, and while it doesn’t reinvent the wheel, it does add meaningful updates in areas that matter—especially for users who care about AI performance, mobile gaming, and reliable connectivity.

Building on the foundation laid by the Dimensity 9400, the 9400+ feels more like a targeted refinement than a generational leap.

Familiar Core Design With a Few Tweaks

At its core, the D9400+ uses a familiar CPU setup: one Cortex-X925 prime core clocked at up to 3.73GHz, along with a mix of Cortex-X4 and Cortex-A720 cores. There’s also 12MB of L3 cache and 10MB of system-level cache (SLC)—plenty to keep multitasking smooth and responsive.

This isn’t a radical rework of the chip’s architecture, but it suggests MediaTek is focusing on squeezing out more efficiency and performance from the setup it already had with the D9400.

Gaming Tech That Aims to Do More With Less

For mobile gamers, MediaTek has put some thought into performance and power savings. The chipset features a 12-core G925 GPU and supports opacity micromaps (OMM)—a rendering trick to improve detail without adding to the GPU load.

There's also an upgraded Frame Rate Converter (MFRC) 2.0+, which can reduce power usage by up to 40%, and Adaptive Gaming Technology 3.0 (MAGT), which adjusts performance on the fly depending on what you're playing. It’s not just about frame rates—it’s about keeping things smooth for longer without draining the battery.

AI That Stays on the Device

One of the more interesting parts of the 9400+ is its AI hardware. The new NPU 890 brings faster on-device large language model (LLM) support and a 20% performance bump for what MediaTek calls “agentic AI.” It supports multiple sizes of Deepseek-R1-Distill models and offers multi-modal processing across apps, meaning your device can do more complex tasks locally without constantly pinging the cloud.

The chip is clearly designed with generative AI features in mind—whether that’s image generation, cross-app assistance, or smarter voice commands.

Small Improvements in the Camera and Audio Department

The D9400+ brings a few updates on the imaging side, including a Gen-AI-powered telephoto system for better zoom, Lightning Snapshot for quicker photos, and support for AI-driven audio focus using up to six microphones. MediaTek also includes 24-bit/384kHz audio playback, which is increasingly relevant as lossless streaming becomes more common.

Connectivity

MediaTek is also stepping up its network capabilities. The 9400+ supports 5G with 4-carrier aggregation (4CC-CA) and download speeds up to 7.3Gbps, along with Wi-Fi 7 support featuring five simultaneous streams across three bands.

There’s even an extension to Bluetooth connectivity up to 10km in ideal conditions, and GNSS upgrades that allow faster satellite signal acquisition—particularly useful in remote areas or during travel.

These changes might not seem flashy, but they add up to more stable connections across a wider range of situations.

Positioning the D9400+ in 2025’s Chipset Landscape

With flagship Android devices increasingly relying on AI-driven software and hardware capabilities, the D9400+ feels like MediaTek’s answer to recent moves from Qualcomm. It’s not a complete overhaul of the Dimensity 9400, but more of a precision upgrade, enhancing the AI, gaming, and connectivity layers where it counts most.
