MediaTek Dimensity 9400 is now official with 35% increase in single core performance

Dimensity 9400 Chipset Overview

CPU 

The Dimensity 9400 features MediaTek’s second-generation All Big Core design. It incorporates a powerful Arm Cortex-X925 core running at over 3.62GHz, alongside three Cortex-X4 cores and four Cortex-A720 cores. This configuration provides a 35% increase in single-core performance and a 28% boost in multi-core performance compared to the Dimensity 9300. Additionally, the chipset is built on TSMC’s second-generation 3nm process, resulting in up to 40% greater power efficiency.

Gaming 

The Dimensity 9400 aims to deliver an immersive gaming experience with its 12-core Arm Immortalis-G925 GPU. This GPU offers a 41% peak performance and 40% faster ray tracing capabilities compared to its predecessor. It also supports opacity micromaps (OMM) for realistic visual effects, resulting in 44% power savings. The chipset integrates MediaTek Adaptive Gaming Technology (MAGT) 3.0 and HyperEngine’s Super Resolution for enhanced gaming performance.

AI Capabilities

A notable feature of the Dimensity 9400 is its 8th Generation NPU, which enhances generative AI performance. It is the first mobile chipset to support on-device LoRA training and high-quality video generation. The new Dimensity Agentic AI Engine (DAE) accelerates large language model (LLM) prompt performance by up to 80% while improving power efficiency by 35%.

Multimedia and Sound Quality

The Dimensity 9400 features the MediaTek Imagiq 1090, which supports HDR video recording across the entire zoom range. Its Smooth Zoom technology facilitates capturing moving subjects while conserving power by up to 14% during 4K60 video capture. Additionally, it supports a maximum camera sensor of 320MP and enables 8K60 video recording. The Dimensity 9400 includes advanced sound recording features, supporting up to 24bit/384KHz BT Audio. It allows for audio recording with up to 6 microphones and incorporates AI Audio Focus to eliminate unwanted noises.

Connectivity and Features

This chipset includes an updated 3GPP Release-17 5G modem with 4CC-CA, achieving up to 7Gbps in sub-6GHz performance. It also features a new 4nm Wi-Fi/Bluetooth combo chip, supporting data rates of 7.3Gbps and Wi-Fi 7 tri-band MLO. MediaTek Xtra Range 3.0 enhances Wi-Fi coverage by up to 30 meters. Furthermore, the Dimensity 9400 is ready for the next generation of trifold smartphones, offering dedicated 3X MIPI-DSI for these devices. It also supports 5G/4G Dual SIM Dual Active.
