MediaTek Dimensity 9400: TSMC 3nm, 50 TOPS AI, and the Closest Race Yet with Snapdragon

MediaTek Dimensity 9400 flagship chip

MediaTek’s Dimensity 9400 lands today, and it’s the Taiwanese fabless giant’s most impressive mobile chip to date. Built on TSMC’s cutting-edge 3nm process — a generation ahead of its predecessor — the 9400 delivers extraordinary gains in both performance and efficiency, addressing the primary criticism of the Dimensity 9300’s thermal characteristics.

The new architecture features a prime Cortex-X925 core clocked at 3.62GHz, three Cortex-X925 performance cores, and four efficiency cores — a more balanced design than the 9300’s all-big-core approach. CPU performance is up 35% versus the 9300, while power efficiency improves by 40% in sustained workloads. The Immortalis-G925 GPU brings 41% better graphics performance with hardware ray tracing enabled by default.

On-device AI is the centrepiece: the new APU 890 delivers 50 TOPS of AI compute, enabling multi-billion parameter LLM inference on-device. MediaTek demonstrated running a 7B parameter model locally in real-time — directly competitive with Qualcomm’s Snapdragon 8 Elite demonstrations.

vivo X200 Pro and OPPO Find X8 Pro are the headline launch devices. The 2024 flagship war between Qualcomm and MediaTek has never been closer.
