- The new NPU 890 offers 20% faster agentic AI performance with support for advanced LLMs, FP8 inferencing, and Speculative Decoding+ for real-time AI applications.
- Equipped with a 12-core Arm Immortalis-G925 GPU and MFRC 2.0+, the chip doubles effective FPS and boosts power efficiency by up to 40% for smoother mobile gaming.
MediaTek has officially launched the Dimensity 9400 Plus (+), an enhanced version of the already powerful Dimensity 9400. Unveiled just a day before the MediaTek Dimensity Developer Conference (MDDC) 2025, this upgraded flagship chipset brings significant improvements across CPU performance, AI capabilities, and connectivity.
Faster CPU
MediaTek Dimensity 9400+ builds on the efficient second-gen TSMC 3 nm process and MediaTek’s signature all-large-core CPU architecture, but gives it a fresh performance boost. At its heart is the new Arm Cortex-X925 core clocked at a blazing 3.73GHz, up from 3.62GHz on the Dimensity 9400.
The rest of the CPU setup includes:
- 3x Cortex-X4 cores running at 3.30GHz
- 4x Cortex-A720 cores at 2.4GHz
This configuration is designed to deliver peak performance for demanding applications while maintaining efficient power consumption, ideal for flagship smartphones in 2025.
Smarter AI with enhanced NPU 890
MediaTek is betting big on AI performance, and the Dimensity 9400+ delivers with an upgraded NPU 890 that pushes generative and adaptive AI to the next level. The chip supports advanced models like:
- Mixture-of-Experts (MoE)
- Multi-Head Latent Attention (MLA)
- Multi-Token Prediction (MTP)
- FP8 inferencing
It also boasts 20% faster AI performance thanks to Speculative Decoding+ (SpD+), accelerating real-time applications like virtual assistants, photo editing, and smart translations. Better yet, this performance is optimized for global LLM support. This expands accessibility across different regions and languages.
GPU upgrades for better gaming and visuals
Gamers and multimedia lovers will appreciate the inclusion of the 12-core Arm Immortalis-G925 GPU, which brings support for opacity micromap (OMM) rendering, enabling more realistic lighting and textures in 3D environments.
One of the standout additions is MFRC 2.0+ (MediaTek Frame Rate Converter), developed alongside game studios, which doubles effective frame rates while improving power efficiency by up to 40%. This makes mobile gaming smoother and less taxing on your battery.
Pro-grade imaging with Imagiq 1090
The Imagiq 1090 ISP from the Dimensity 9400+ continues to impress. It supports HDR video recording across the full zoom range, and with Smooth Zoom tech, users can now lock in both visual and audio targets even when subjects are in motion.
Camera hardware support includes:
- Up to 320MP camera sensors
- Advanced zoom and tracking features for creators and professionals
Next-level connectivity: Bluetooth to satellites
The Dimensity 9400+ doesn’t just focus on speed—it redefines range and reliability:
- Direct phone-to-phone Bluetooth connections now reach up to 10 km, a massive 6.6x increase over the Dimensity 9400.
- Integrated BeiDou satellite support delivers 33% faster TTFF (time to first fix) even when cellular signals are weak or unavailable.
- Supports Wi-Fi 7 with tri-band concurrency and five streams for ultra-fast and stable connections.
- MediaTek Xtra Range 3.0 extends Wi-Fi coverage by up to 30 meters, ensuring strong signals throughout larger homes and offices.
