Dimensity 9400: The King of Performance and Efficiency, Leading the New Era of Mobile Platform Chips

The past October marked the official start of a new round of fierce competition among flagship mobile platform chips. As the smartphone market intensifies and the demand for performance and energy efficiency evolves, the technological path of flagship SoC chips is gradually diverging. The "dual-winner" experience of combining performance and energy efficiency is what truly excites users and gamers. MediaTek, together with numerous partners, has launched the Dimensity 9400 flagship SoC chip, which leverages its advanced second-generation all-large-core architecture design to create a 5G flagship intelligent AI chip that is "highly intelligent, high-performance, high-efficiency, and low-power," offering users an "experience-centric" excellence.

Dimensity 9400 Performance Buff Maxed Out

The Dimensity 9400 adopts TSMC's most advanced second-generation 3nm process, featuring Armv9.2 "Blackhawk" architecture. Its second-generation all-large-core CPU architecture includes one Cortex-X925 super-large core with a maximum frequency of 3.62GHz (2MB L2 cache), three Cortex-X4 super-large cores (1MB L2 cache), four Cortex-A720 large cores (512KB L2 cache), a 12MB L3 cache, and a 10MB SLC system-level cache. This design not only significantly improves performance but also contributes to longer battery life on end devices.

Starting with the Dimensity 9300 chip, MediaTek fundamentally changed the design of smartphone SoC chips, pioneering and leading the "all-large-core" era, a feature that continues in the Dimensity 9400 chip. All CPU cores are equipped with "out-of-order execution" pipelines, thus bypassing small CPU cores. This industry-leading design seamlessly integrates the latest advancements in Arm CPU architecture with MediaTek's most advanced energy efficiency technology. The "all-large-core" architecture delivers higher multi-threaded performance without sacrificing DoU (Daily Usage Time) value. Software automatically manages task allocation to appropriate CPU cores. The operating system directly understands the high-performance and high-efficiency cores within the system and can dynamically allocate each task based on the required performance.

The Cortex-X925 super-large core doesn't focus on significantly raising frequencies, yet the Dimensity 9400's performance still surpasses all others. Geekbench6 benchmark scores reveal a CPU single-core score of 3040 and a multi-core score of 9600, representing a substantial leap compared to the previous generation. The Dimensity 9400's single-core performance has increased by 35% and its multi-core performance by 28% compared to the previous generation, while power consumption has decreased by 40%, and IPC performance has increased by 15%. This signifies that the processor can execute more instructions at the same frequency, leading to performance enhancement. Additionally, the Dimensity 9400's L2 cache has doubled, and its L3 cache capacity has increased by 50%, significantly accelerating the CPU's data retrieval speed and further boosting processing performance.

GPU: Designed for a PC-Level Gaming Experience

Research institutions predict that the mobile gaming market will grow at a remarkable 15.5% CAGR (Compound Annual Growth Rate) until 2032, becoming a major driver of computing demands. As display refresh rates, game resolutions, and in-game visual effects become increasingly sophisticated, the demands on CPU and GPU performance continue to rise.

MediaTek has adopted a PC-level architectural design approach, ensuring the Dimensity 9400 not only delivers stable top-tier performance but also maintains its high-performance, high-efficiency attributes. In terms of GPU, the Dimensity 9400 specifically utilizes a 12-core Arm Immortalis-G925, delivering a 41% peak performance increase, a 44% power reduction, and a significant 40% boost in ray tracing performance. It boasts a truly formidable and steady performance. GFXBench testing reveals that the Dimensity 9400 excels in 1440P off-screen Vulkan scenarios, achieving a score of 134 frames, surpassing the leading flagship competitors in the market.

In the post-full-frame era, the Dimensity 9400's advantage lies not only in its powerful GPU performance but also in its continued cool operation facilitated by low power consumption. Extensive testing reveals that the majority of heavy-load gaming scenarios on Dimensity 9400 flagship phones maintain an average power consumption below 6W, with even better performance in everyday usage. For instance, in "Genshin Impact" testing, the Dimensity 9400 delivers an average frame rate of 60fps with a power consumption of 3.63W; in "Honkai: Star Rail," the average frame rate reaches 59.8fps, consuming only 3.92W of power.

The Dimensity 9400 flagship core supports the PC-level Dimensity OMM ray tracing engine, significantly boosting graphics processing performance while reducing power consumption. It renders realistic game lighting effects, providing a high-quality, persistently smooth mobile gaming experience. Notably, "Dark Area Breakaway" mobile game supports 90fps full-scene mobile ray tracing, setting a new benchmark in mobile ray tracing.

In practical experience, the Dimensity 9400 chip boasts an outstanding power-efficiency ratio, being well-suited for both daily use and gaming performance. Additionally, in certain scenarios like prolonged operation of specific games, the chip's excellent thermal management contributes to extended battery life. The flagship chip's precise performance control, coupled with the Star Speed Engine-super-resolution technology, offers impressive game visuals while saving power consumption. For example, by achieving slightly higher frame rates while maintaining lower power consumption, the Dimensity 9400 provides more consistent frame rates, significantly reducing micro-stutter, resulting in a smoother user experience.

Leading Rapid Industry Technological Development

In an increasingly competitive smartphone market, MediaTek boldly innovates to create the Dimensity 9400 flagship chip, addressing performance evolution, computing power enhancement, and multi-tasking demands. Through breakthroughs in CPU, GPU, energy efficiency, and other underlying architectural technologies, the chip drives significant leaps and improvements in device performance, user gaming, battery life, and daily experience, paving a path toward rapid industry technological advancements.

The emergence of the Dimensity 9400 not only brings users unprecedented performance and energy efficiency experiences but also heralds a new era of mobile platform chip technology. In the future, MediaTek will continue to prioritize innovation, creating more powerful, intelligent, and energy-efficient mobile chips, leading the direction of mobile technology development.
