MediaTek Dimensity 8400: Future of Smartphone Performance

MediaTek Dimensity 8400

With the MediaTek Dimensity 8400, it have once again upped the standard for amazing performance and power efficiency in high-end smartphones.

This chip combines a premium 7-core graphics engine, an unmatched all-big-core CPU design, a future-proof 5G Advanced modem, and a Gen-AI NPU for seamless creative and spectacular HDR images.

Epic All Big Core CPU

By elevating creative all-big core design to a new level, we’re expanding it dominance in the global smartphone market. Eight Arm Cortex-A725 processors are incorporated into the MediaTek Dimensity 8400, resulting in an incredible CPU design with tremendous performance.

Increased multi-core performance of up to 41%

Key Features

Exceptional Power Efficiency

The MediaTek Dimensity 8400 achieves class-leading power efficiency by accurately controlling the power curve and performance of its all-big core CPU design. Larger in-chip caches improve this by guaranteeing that more crucial data is available for use right away.

  • 44% less power during peak times
  • 100 percent L2 cache
  • +50% L3 cache
  • +25% SLC cache

Premium Graphics Engine

When paired with the MediaTek Frame Rate Converter (MFRC), the Arm Mali-G720 MC7 GPU offers incredible gaming performance. The G720 GPU extends power savings and improves peak performance by requiring 30% less memory bandwidth.

  • Higher peak performance by more than 24%
  • -42% electricity consumption

HyperEngine Adaptive Gaming Technology 3.0 by MediaTek

Take advantage of a developing ecosystem of games that support MAGT and can use MediaTek unique gaming improvement technology.

  • MAGT’s increased power efficiency
  • The Network Observation System (NOS) maximises network connectivity, enhances power efficiency, and permits accurate 5G/Wi-Fi switching.
  • Optimisation of touch latency

Most Powerful Generative AI in its Class

For typical activities like translation, rewriting, reply construction, AI recording, and creating images, videos, music, and more, the most recent 8th-generation NPU provides cutting-edge Gen-AI capabilities and outstanding in-device processing speed.
The new Dimensity Agentic AI Engine (DAE) from MediaTek, which is intended to transform conventional AI applications into complex agentic AI applications, is also integrated into the MediaTek Dimensity 8400.

The MediaTek NPU 880 supports the most recent popular LLM/SLM/LMMs worldwide and makes use of MediaTek’s expanding generative AI ecosystem. Software designers may swiftly incorporate the most recent Gen-AI innovations with ongoing enhancements to the NeuroPilot toolbox, which enables them to be the first to market with the newest concepts and functionalities.

  • +20% quicker floating-point and integer operations
  • A +18% increase in power efficiency
  • Text generation is +33% faster (Baichuan 4B)
  • Stable Diffusion v1.5 is +21% quicker.
  • Support for diffusion transformers
  • Compression technique of NeuroPilot
  • Technology for mixed-precision INT4 quantisation
  • Improved LLM speculative speed assistance

Imagiq 1080: Flagship-grade Image Quality

Utilise QPD remosaic technology to gather more light, focus more quickly and precisely, and create high-resolution image quality that significantly outperforms other platforms for photography and video recording.

  • 100% PDAF in-sensor zoom (IS Zoom)
  • HDR video capture across the whole zoom range
  • 12% less power is used when recording 4K HDR video.

5G Advanced Modem

The 5G-A modem from MediaTek is prepared for markets using the upcoming cellular network generation.

  • Up to 3CC-CA
  • Up to 5.17 Gbps of speed
  • More 5G power efficiency with MediaTek Ultra Save 3.0+
