MediaTek has unveiled its latest innovation in mobile technology, the Dimensity 8400, marking a new milestone in smartphone performance and efficiency. This system-on-chip (SoC) introduces the All Big Core architecture to premium smartphones for the first time, promising groundbreaking advancements in Generative AI (Gen-AI), mobile gaming, and power efficiency. Building on the success of the flagship Dimensity 9400, the Dimensity 8400 is designed to deliver unparalleled performance while redefining the premium smartphone experience.
A Leap in Performance and Power Efficiency
At the heart of the Dimensity 8400 is an eight-core Arm Cortex-A725 processor, clocked at up to 3.25GHz. This new architecture delivers a 41% improvement in multi-core performance over its predecessor, the Dimensity 8300. Despite its powerful performance, the chip manages to achieve a 44% reduction in peak power consumption, showcasing MediaTek’s ability to balance performance with energy efficiency.
For gaming enthusiasts, the Dimensity 8400 features an Arm Mali-G720 GPU, which boosts peak performance by 24% and improves power efficiency by 42% compared to the previous generation. Integrated technologies like MediaTek Frame Rate Converter (MFRC) and Adaptive Gaming Technology (MAGT) 3.0 ensure smoother gameplay and real-time optimization for mobile gaming experiences.
Advancing Generative AI with NPU 880 and Dimensity Agentic AI Engine
The Dimensity 8400 leverages MediaTek’s NPU 880, a powerful neural processing unit designed to support a broad range of AI applications, including large language models (LLMs), speech-to-speech (SLMs), and media generation (LMMs). These capabilities enable advanced AI-powered features such as:
- Real-time language translation and contextual replies.
- AI-powered transcription and rewriting.
- Dynamic media generation for creative tasks.
Additionally, the Dimensity 8400 integrates the Dimensity Agentic AI Engine (DAE), originally introduced in the Dimensity 9400. This innovative technology transforms traditional AI into agentic AI, enabling applications to anticipate user needs and adapt to individual preferences. With DAE, developers can create next-generation apps that redefine the smartphone user experience.
Enhanced Imaging and Connectivity
MediaTek continues to push the boundaries of mobile photography with its Imagiq 1080 ISP, which utilizes QPD remosaic technology to capture more light and improve autofocus accuracy. The ISP supports HDR video recording across the entire zoom range, delivering exceptional video quality even in challenging lighting conditions.
The Dimensity 8400 also features cutting-edge connectivity with its 5G-A modem, which supports up to 5.17Gbps speeds and advanced 3CC-CA carrier aggregation. The chip’s Network Observation System (NOS) ensures seamless transitions between 5G and Wi-Fi, enhancing both connectivity and power efficiency.
Display and Multitasking Features
The SoC supports WQHD+ displays with refresh rates up to 144Hz, offering ultra-smooth visuals for gaming and media consumption. Dual-screen support further enhances multitasking, making the Dimensity 8400 an ideal choice for productivity-focused users.
Market Availability
MediaTek announced that the first smartphones powered by the Dimensity 8400 will hit the market by the end of 2024. The chip is set to empower flagship and premium smartphones, bridging the gap between performance and affordability while bringing advanced AI and gaming capabilities to a wider audience.
Driving Innovation in the Semiconductor Industry
Dr. Yenchi Lee, General Manager of MediaTek’s Wireless Communications Business Unit, emphasized the company’s vision: “The Dimensity 8400 redefines premium smartphone experiences by combining agentic AI capabilities, immersive gaming performance, and unparalleled efficiency. We are proud to deliver innovation that enables consumers to unlock new possibilities without compromise.”
