MediaTek has launched the Dimensity 9400, the company’s new flagship smartphone chipset optimised for edge-AI applications, immersive gaming, better photography, and more. The Dimensity 9400, the fourth and latest in MediaTek’s flagship mobile SoC lineup, offers a massive boost in performance with its second-generation All Big Core design built on Arm’s v9.2 CPU architecture, combined with the most advanced GPU and NPU for extreme performance in a super power-efficient design.
The Dimensity 9400 adopts MediaTek’s second-gen All Big Core design, integrating one Arm Cortex-X925 core operating over 3.62GHz, combined with 3x Cortex-X4 and 4x Cortex-A720 cores. This design offers 35% faster single-core performance and 28% faster multi-core performance compared to MediaTek’s previous generation flagship chipset, the Dimensity 9300. Built on TSMC’s second-generation 3nm process, the Dimensity 9400 is up to 40% more power-efficient than its predecessor, allowing users to enjoy longer battery life.
