Dimensity 9400: A Comprehensive Upgrade in Performance, Power Efficiency, and Gaming, Ushering in a New Era for Mobile Chips

On October 9, 2023, MediaTek launched its new flagship chip, the Dimensity 9400. This chip boasts significant upgrades across key areas like CPU, GPU, and AI, setting numerous industry records and establishing itself as the undisputed performance and experience benchmark for flagship smartphones. Its exceptional performance and power efficiency have quickly garnered the favor of manufacturers like vivo and OPPO, making it the chip of choice for their high-end flagship models.

CPU Architecture Revolution: The Perfect Balance of Performance and Power Efficiency

The Dimensity 9400 adopts a second-generation all-large-core CPU architecture, featuring a 3.62GHz Cortex-X925 ultra-core, three Cortex-X4 super-cores, and four Cortex-A720 large-cores. Compared to its predecessor, it boasts double the L2 cache capacity and a 50% increase in L3 cache, significantly improving both single-core and multi-core performance. This architecture not only delivers powerful processing capabilities but also ensures excellent power efficiency, allowing the phone to maintain long battery life even under heavy workloads.

Immortalis-G925 GPU: Setting a New Benchmark for Mobile Graphics Processing

The Dimensity 9400 is equipped with ARM's latest Immortalis-G925 GPU, offering a 41% performance improvement over the previous generation. Two key advancements set this GPU apart: firstly, its Fragment Prepass technology efficiently discards hidden, ineffective screen content, rendering only the visible areas to significantly boost rendering speed and reduce power consumption; secondly, it doubles the throughput of the Tiler unit, further enhancing graphics processing efficiency.

In real-world game testing, the Dimensity 9400 demonstrates its powerful graphics processing capabilities. GFXBench tests show its performance significantly outperforming other flagship competitors, firmly establishing it as the king of mobile GPUs. Critically, the Immortalis-G925 GPU achieves this significant performance boost while simultaneously reducing power consumption by 44%. This translates to lower heat generation, longer battery life, and a more consistently smooth gaming experience during intensive gameplay.

Taking the OPPO Find X8 Pro as an example, the Dimensity 9400 delivers stable high frame rates in popular games like Genshin Impact and Honkai: Star Rail, maintaining low power consumption and temperature. In Genshin Impact's Sumeru City benchmark test at the highest settings and 60fps, the average frame rate reached 60.51 FPS, with a maximum rear-case temperature of only 36.2. In Honkai: Star Rail's Stargazer Navis benchmark test at the highest settings and 60fps, the average frame rate remained steady at 59.62 FPS, with a maximum rear-case temperature of 38.7. In contrast, while the Apple A18 Pro might slightly outperform in raw GPU benchmark scores, it exhibits noticeable performance degradation and temperature increase under high-load gaming, significantly impacting the gaming experience. The Dimensity 9400, however, maintains high frame rates for extended periods while effectively managing power consumption and heat, providing users with an exceptional gaming experience.

OMM Ray Tracing Engine: The Dawn of Mobile Ray Tracing

The Dimensity 9400 is the first to support MediaTek's self-developed OMM Ray Tracing Engine, bringing near PC-level ray tracing effects to mobile devices. The OMM Ray Tracing Engine uses intelligent algorithms to optimize light and shadow calculations, accurately rendering irregular shapes and translucent objects, significantly reducing shader workload. This ensures excellent image quality without excessive performance or power consumption.

This technology makes mobile ray tracing a reality, not a luxury. MediaTek's deep collaboration with Dark Zone: Battle Royale has resulted in the launch of a 90FPS ray tracing gaming experience, allowing players to enjoy PC-grade ray tracing visuals on their mobile devices, achieving a perfect balance between image quality and frame rate for a more immersive and realistic gaming experience.

AI Performance Enhancement: Enabling Richer AI Applications

The Dimensity 9400 incorporates the new generation NPU 890, significantly enhancing AI performance and achieving a leading position on the Zurich AI Benchmark. OPPO, leveraging the Dimensity 9400's powerful AI capabilities and large AI models, has created a wealth of AI-powered features, resulting in significant efficiency improvements and positive user reviews.

Deep Collaboration with Manufacturers: Unleashing Chip Potential

The vivo X200 series and OPPO Find X8 series are the launch models for the Dimensity 9400. Both manufacturers have collaborated extensively with MediaTek, developing the "Blue Crystal Chip" and "Tide Engine" co-tuning solutions respectively. These solutions delve deep into the chip architecture, optimizing system resource allocation to further unleash the flagship performance of the Dimensity 9400 and deliver a comprehensive user experience enhancement.

vivo's collaboration with MediaTek, through the "Blue Crystal Chip" deep tuning, maximizes the Dimensity 9400's performance, enhancing the overall experience of the vivo X200 series. OPPO, through its "Tide Engine" technology, reshapes the system cache allocation mechanism, enabling intelligent dynamic cache allocation and full-stack algorithm acceleration, significantly reducing memory access frequency and boosting algorithm execution efficiency by up to 3 times. This fully utilizes the Dimensity 9400's powerful performance and solidifies its position as a high-end flagship chip.

Conclusion: Dimensity 9400 Leads the New Era of Mobile Chips

The Dimensity 9400 represents a comprehensive and groundbreaking upgrade, reaching the industry's pinnacle in CPU, GPU, AI, and power efficiency. Its outstanding performance, advanced ray tracing technology, and deep collaboration with manufacturers make it a leader in the current mobile chip landscape. The strong market performance of the vivo X200 series and OPPO Find X8 series serves as compelling evidence of the Dimensity 9400's market competitiveness and high-end positioning. As more manufacturers adopt the Dimensity 9400, it is poised to further drive improvements in mobile experiences and usher in a new era for mobile chips.
