MediaTek’s newest chipset, the Dimensity 8400 is out and it features “All Big Core” CPU design. Compared to its predecessor, the Dimensity 8300, Mediatek says the Dimensity 8400 delivers a 41% improvement in multi-core performance while reducing energy consumption by approximately 44%.
The architecture of the Dimensity 8400 takes inspiration from MediaTek's flagship Dimensity 9400. It is powered by an eight-core Arm Cortex-A725 CPU, clocked up to 3.25GHz. The Mali-G720 GPU works in harmony with MediaTek's Frame Rate Converter (MFRC) for smoother gameplay, while MediaTek Adaptive Gaming Technology (MAGT) 3.0 is said to ensure real-time optimisation of game and app performance. The chipset supports WQHD+ displays with up to a 144Hz refresh rate, along with LPDDR5X RAM, UFS 4.0 storage, Wi-Fi 6E, and Bluetooth 5.4.
A key highlight of the Dimensity 8400 is its emphasis on generative AI. The integrated NPU 880 supports large language models (LLM), small language models (SLM), and multimodal large language models (LMM), enabling advanced AI applications such as AI-powered translation, text rewriting, contextual responses, AI recording, and media generation.

The Dimensity 8400 also integrates MediaTek’s Dimensity Agentic AI Engine (DAE), first introduced with the Dimensity 9400, to enhance the development of more advanced and personalised AI applications for devices.
Built on TSMC’s 2nd generation 4nm process, the Dimensity 8400 supports camera sensors up to 320MP and is equipped with the Imagiq 1080 14-bit HDR ISP. This technology utilises QPD (Quad-Pixel Detection) to capture more light, focus more quickly and accurately, and deliver high-resolution images. Additionally, the chip enables HDR video recording across the entire zoom range, allowing users to capture stunning videos with superior quality.
