The Dimensity 9400e is the latest addition to MediaTek’s family of flagship-class processors, providing a wider variety of options and functionality for device makers.
With improved levels of performance and energy efficiency it supports enhanced artificial intelligence, connectivity, imaging, and gaming capabilities.
“With the launch of the Dimensity 9400e, MediatTek is expanding its family of leading mobile platforms to ensure both device makers and users can select from a larger range of flagship experiences than ever before,” said Dr. Yenchi Lee, General Manager of MediaTek's Wireless Communications Business Unit.
The chipset has been built on TSMC's third-generation 4nm process and it features an All Big Core CPU architecture, including four Cortex-X4 super cores with clock speeds of up to 3.4GHz and four Cortex-A720 big cores with clock speeds of 2.0GHz.
This is architecture meets the performance demands of multitasking and complex applications while maintaining energy efficiency.
The chipset is equipped with a 12-core GPU, Immortalis-G720, providing powerful graphics rendering capabilities for smartphones and gamers and it supports hardware-level mobile ray tracing technology, delivering console-level global illumination effects to significantly enhance gaming immersion.
The chipset supports MediaTek Adaptive Gaming Technology (MAGT 2.0), enabling real-time performance scheduling between the chipset and gaming applications delivering high-frame-rate stability and low power consumption. Furthermore, the Dimensity 9400e supports MediaTek Frame Rate Converter (MFRC 2.0+), which can reduce power consumption by up to 40% when enabled.
The Dimensity 9400e supports the latest MediaTek NeuroPilot SDK, enabling generative AI applications and services to deliver fast, more personalised, and secure experiences. It features enhanced inference decoding technology (SpD+), accelerating the computational efficiency of large language models.
It also supports global mainstream large language models and small language models, enabling on-device operation of DeepSeek-R1-Distill (Qwen1.5B/Llama7B/Llama8B) models, as well as Gemini Nano with Multimodality, and LLaVA-1.5 7B.
The Dimensity 9400e is also equipped with a flagship 18-bit RAW ISP, supporting AI semantic segmentation video engines capable of 16-layer image semantic segmentation. It also supports high-dynamic noise reduction for recordings with three microphones.
Leveraging advanced image and audio capture technologies, the chipset delivers professional-grade video recording effects for smartphone photography.
Key features of the MediaTek Dimensity 9400e mobile chipset include:
- Bluetooth connection range between phones up to 5km within line of sight
- Sub-6GHz four-carrier aggregation (4CC-CA) with theoretical peak network download speeds of up to 7Gbps
- Wi-Fi 7 tri-band concurrency (5 data streams) with theoretical peak transmission speeds of up to 7.3Gbps
- MediaTek 5G UltraSave 3.0 power-saving technology
- Multi-mode dual-SIM dual-active functionality
The first smartphones powered by the MediaTek Dimensity 9400e mobile chipset are expected to launch this month.
