MediaTek Dimensity 9400: Performance King, AI Pioneer, Ushering in a New Era for Mobile Chips

MediaTek officially unveiled its latest flagship mobile platform, the Dimensity 9400, on October 9th. Building upon the all-large-core design philosophy of the Dimensity 9300, this processor has achieved significant advancements across CPU, GPU, AI, and connectivity, pushing the boundaries of performance and efficiency to become a new industry benchmark.

Powered by TSMC's 3nm Process, Delivering Performance and Efficiency Gains

The Dimensity 9400 is manufactured using TSMC's second-generation 3nm process, integrating as many as 29.1 billion transistors, a 28% increase over the Dimensity 9300. This advanced technology not only delivers higher performance but also results in reduced power consumption and a smaller footprint.

All-New CPU Architecture, Delivering Significant Performance Boost

The Dimensity 9400's CPU retains the octa-core design but boasts a major upgrade in architecture, transitioning from four X4 and four A720 cores to a new configuration featuring one X925 ultra-ultra large core, three X4 ultra-large cores, and four A720 large cores. The X925 ultra-ultra large core is the latest generation of ultra-powerful cores, with a clock speed boosted to 3.62GHz, representing a near 400MHz increase over the Dimensity 9300's peak frequency. This results in a single-core performance improvement exceeding 35%. Optimizations to the multi-core scheduling mechanism further enhance the CPU's overall performance.

Immortalis-G925 GPU, Featuring Mobile-First Ray Tracing Debut

The Dimensity 9400's GPU upgrades from the Immortalis-G720 to the latest flagship Immortalis-G925, marking a further leap in performance. This GPU stands out with its mobile-first implementation of OMM, a ray tracing technology comparable to PC-grade solutions. It allows for precise rendering of irregular shapes and semi-transparent objects, significantly reducing shader workload and enhancing ray tracing image quality.

Performance Testing: Leading Across the Board, Breaking Records

In real-world testing, the Dimensity 9400 delivers impressive performance. It achieves a benchmark score of nearly 2.83 million on Antutu, representing a 32.5% increase over the Dimensity 9300 and surpassing the Qualcomm Snapdragon 8 Gen 3. GeekBench 6 scores approach 3,000 for single-core and 10,000 for multi-core, indicating a 32% single-core and 21% multi-core performance improvement compared to the Dimensity 9300. In GFXBench tests, it achieves a remarkable 380FPS in Manhattan 3.1 and 128FPS in Aztek Ruins. 3DMark SteelNomad scores 2533 with an average frame rate of 18.77FPS, representing an approximate 48% and 44% improvement over the Dimensity 9300. In 3DMark OMM testing, the Dimensity 9400 achieves a measured 93.75FPS, a significant 34% improvement over the performance without OMM enabled.

Gaming Experience: Smooth Full Frame Rates, Lower Power Consumption

The Dimensity 9400 also shines in gaming. In Genshin Impact at ultra-high settings, running through Sumeru City for 30 minutes results in nearly full 60FPS with an average power consumption of 3.636W, a 17% reduction compared to the Dimensity 9300. In Honkai: Star Rail at ultra-high settings and 60FPS mode, running through the Star Raft Sea for 30 minutes yields an average frame rate approaching 59.7FPS with an average power consumption of 3.922W, saving nearly 24% compared to the Dimensity 9300. In miHoYo's latest masterpiece, Honkai: Star Rail, at 60FPS mode and maximum settings, 20 minutes of gameplay achieves an average frame rate of 59.8FPS with an average power consumption that remains below 4.2W.

Evolved AI Engine: On-device Generation, Enriched Gameplay

The Dimensity 9400 integrates the eighth-generation NPU890 AI engine, debuting worldwide support for on-device LoRA solutions. This enables on-device personal digital avatar applications, allowing data collection, model training, and usage without internet connectivity, protecting personal privacy. Moreover, the Dimensity 9400 supports on-device video generation, enabling the creation of high-quality short videos using text, images, and other inputs. Diffusion models see a performance boost of 100%, supporting text-to-image, image-to-image, and image-to-animated image applications.

Conclusion: A New Era for Mobile Chips, Leading Industry Innovation

With its unparalleled performance, leading AI technology, and innovative ray tracing capabilities, the Dimensity 9400 sets a new benchmark for mobile chips. Flagship smartphones powered by the Dimensity 9400 are expected to deliver an exceptional performance experience and a wealth of application possibilities, driving innovation across the entire industry.
