 8400 SoC has an eight-core Arm Cortex-A725 processor operating at up to 3.25GHz, providing 41 per cent higher multi-core performance compared to the previous generation chip, the Dimensity 8300. The Dimensity 8400 is designed to precisely control the CPU’s performance and power curve, offering a 44 per cent reduction in peak power use compared to its predecessor.  

Additionally, the Dimensity 8400 supports immersive gaming experiences with its Arm Mali-G720 GPU that offers 24 per cent higher peak performance and 42 per cent greater power efficiency than the Dimensity 8300. The Mali-G720 GPU works in tandem with MediaTek Frame Rate Converter (MFRC), which delivers smoother gameplay, and MediaTek Adaptive Gaming Technology (MAGT) 3.0, which optimises game and app performance in real-time.

The built-in MediaTek Imagiq 1080 ISP leverages QPD remosaic technology to capture more light, focus faster and more accurately, and produce high-resolution images. The chip also supports HDR recording throughout the entire zoom range so users can take incredible videos.

With MediaTek’s NPU 880, the Dimensity 8400 supports mainstream LLM/SLM/LMMs across the globe so users can enjoy the latest Gen-AI applications such as translation, rewriting, contextual replies, AI recording, and media generation. 

The Dimensity 8400 also integrates MediaTek’s DAE, which the company recently introduced in the flagship Dimensity 9400 SoC, enabling developers to create innovative agentic AI applications that anticipate user needs and adapt to their preferences.

“MediaTek is redefining premium smartphone experiences with the Dimensity 8400, unleashing creativity with generative and agentic AI applications and taking mobile gaming even further,” said Dr. Yenchi Lee, General Manager of MediaTek's Wireless Communications Business Unit. 

“Our All Big Core design, which we’ve also integrated into our flagship chips, highlights the impressive performance and efficiency that can go hand-in-hand so consumers don’t have to compromise," Dr. Yenchi added.
