MediaTek has launched its new flagship chip, the Dimensity 9400+, aimed at improving AI, gaming, and connectivity on smartphones. It features an All Big Core CPU setup with one Cortex-X925 core at 3.73GHz, three Cortex-X4 cores, and four Cortex-A720 cores. This design boosts both single-core and multi-core performance for Android flagship devices.
The chip includes the upgraded MediaTek NPU 890, which supports on-device large language models using Mixture-of-Experts (MoE), Multi-Head Latent Attention (MLA), and FP8 inferencing. Speculative Decoding+ speeds up AI tasks by 20%, while the Dimensity Agentic AI Engine helps developers build advanced AI systems.
For gaming, the 12-core Arm Immortalis-G925 GPU brings better visuals with PC-level features like opacity micromap for detailed textures. MediaTek’s Frame Rate Converter 2.0+ doubles the frame rate and cuts power use by 40%.
Connectivity also sees major upgrades. The chip extends Bluetooth range up to 10km (line-of-sight), supports BeiDou for 33% faster GPS-like location fixes even without mobile networks, and includes Wi-Fi 7 with tri-band support. The 5G modem reaches 7Gbps download speeds and supports Dual SIM Dual Active use.
On the camera side, the Imagiq 1090 image processor enables HDR video at all zoom levels and adds Smooth Zoom for steady subject tracking. For audio, it supports 24-bit recording through six built-in microphones with AI enhancement.
According to MediaTek, the Dimensity 9400+ is built to handle heavy workloads efficiently while giving developers more tools to build better AI apps. OPPO has already launched the flagship Find X8s and Find X8s+ smartphones featuring this new chip in China.
