MediaTek, the Taiwanese fabless semiconductor company, has unveiled its newest chipset, the Dimensity 8400, aimed at the high-end smartphone market. This launch comes after the Dimensity 8300 SoC was released last year and is engineered to provide improved generative AI capabilities. The Dimensity 8400 enhances the core technology of the flagship Dimensity 9400, incorporating advanced features intended to enhance the overall user experience. The initial smartphones utilizing this chipset are anticipated to be available by the conclusion of 2024.

MediaTek Dimensity 8400: All Big Core CPU Design

The Dimensity 8400 represents the inaugural premium smartphone chipset to incorporate an All-big-core CPU architecture. This design, in conjunction with a high-performance NPU, markedly enhances the chipset's capacity to expedite Generative AI tasks. Furthermore, MediaTek has unveiled the Dimensity Agentic AI Engine (DAE), a platform that redefines traditional AI applications into more interactive and agentic AI experiences.

This chipset features an eight-core Arm Cortex-A725 processor, capable of reaching clock speeds of up to 3.25GHz, which results in a 41% increase in multi-core performance compared to its predecessor, the Dimensity 8300. Additionally, it achieves a 44% decrease in peak power consumption, thereby improving energy efficiency.

MediaTek Dimensity 8400: Optimised Gaming and Gen AI Features

For gamers, the Dimensity 8400 features the Arm Mali-G720 GPU, which offers a 24% enhancement in peak performance and a 42% boost in power efficiency when compared to the Dimensity 8300. It operates in conjunction with MediaTek's Frame Rate Converter (MFRC) and Adaptive Gaming Technology (MAGT) 3.0, ensuring a smoother and more optimized gaming experience in real time.

In the realm of Generative AI, the Dimensity 8400 utilizes MediaTek's NPU 880, which is compatible with global LLM/SLM/LMM applications. This capability allows users to access advanced AI functionalities, including translation, rewriting, contextual responses, AI recording, and media generation. Additionally, the DAE facilitates developers in creating cutting-edge AI applications that anticipate user requirements.

MediaTek Dimensity 8400: Advanced Imaging and Connectivity Features

The chipset is equipped with the MediaTek Imagiq 1080 ISP for imaging, which employs QPD mosaic technology to improve both focusing speed and precision. This feature allows for high-resolution image capture and supports HDR recording across the entire zoom spectrum, resulting in outstanding video quality.

Moreover, the Dimensity 8400 is integrated with a powerful 5G-A modem that facilitates 3CC-CA (Carrier Aggregation), enabling data transfer rates of up to 5.17 Gbps. This capability guarantees seamless connectivity and swift download speeds. Its advanced Network Observation System (NOS) technology enhances the transition between 5G and Wi-Fi, thereby improving power efficiency and overall network performance. Additionally, the chipset accommodates WQHD+ resolution with a refresh rate of up to 144Hz, making it ideal for high-performance gaming and multimedia tasks, while also supporting dual-screen functionality for enhanced multitasking on compatible devices.
