The new MediaTek Dimensity 9400 raises the bar for flagship smartphone chipsets thanks to upgrades on all fronts, enabling it to deliver the ultimate smartphone experience. Discover what's inside MediaTek's fastest flagship smartphone chip in our easy-to-digest infographic, or read on to find out about some of the fantastic tech what's packed inside this super-chip:
Ultimate All Big Core CPU
Last year, MediaTek unveiled its innovative all-big-core CPU design with the Dimensity 9300, earning critical acclaim. The Dimensity 9400 introduces the second generation of this architecture, incorporating a new Cortex-X925 alongside three Cortex-X3 and four Cortex-A720 processors. This tri-core design pushes performance to new extremes, delivering up to 35% faster single-core performance and 28% faster multi-core performance compared to the previous-generation flagship chip. These processors are also paired with larger on-chip caches, which bring more essential data closer to the CPU, enhancing efficiency and improving power management.
Unmatched Power Efficiency
The Dimensity 9400 leverages the latest 2nd-generation TSMC 3nm chip production process, delivering up to 40% greater power efficiency and improved performance per milliwatt compared to our previous-generation flagship chip. Combined with MediaTek’s expertise in system-wide power management with an emphasis on sustainability, smartphones powered by the Dimensity 9400 will exceed expectations by being consistently fast while offering long-lasting battery life.
LPDDR5X up to 10667MT/s
MediaTek continues to support the world’s fastest smartphone memory standards with each new generation of flagship chips, this time breaking the 10K MT/s barrier and enabling the latest LPDDR5X-10667. Faster memory provides more bandwidth for the data-hungry in-chip CPU, GPU, and NPU, ensuring the system unlocks its maximum potential.
PC-grade Gaming Goes Mobile
The Dimensity 9400 features PC-grade hardware ray-tracing capabilities and can accelerate OMM-enabled games, enhancing visual details such as realistic effects in complex materials like vegetation, hair, and feathers without significantly increasing model complexity. Powered by a 12-core GPU delivering these advancements and supported by MediaTek Adaptive Gaming Technology 3.0 for sustained FPS, mobile gaming is ushered into a new era of visual realism.
Agentic AI and Generative AI
MediaTek has consistently invested in AI research to bring edge AI processing to its diverse product verticals. In addition to setting a new benchmark for peak performance in existing AI activities, the 8th-generation NPU, first introduced in the Dimensity 9400, now supports AI agents. This advancement enables sensing across multiple domains, fostering a more intuitive understanding that drives precise and personalized actions. The Dimensity Agentic AI Engine (DAE) empowers developers to leverage this groundbreaking technology with greater ease, offering them the freedom to create more intuitive, agentic experiences.
Furthermore, Generative AI capabilities have been significantly enhanced in multiple areas. The NPU 890 enables the world’s first high-quality on-device video generation, the first on-device LoRA training, and supports critical new technologies found in the latest language models, including Diffusion Transformer (DiT) and Mixture of Experts (MoE).
Zoom and Enhance
What once belonged to the realm of sci-fi storylines in TV shows is now a reality. The Dimensity 9400 enables up to 100x zoom with generative AI corrective fill, which actively learns and provides sharp, clear details in images, eliminating the fuzzy, pixelated results of the past. In today’s era of multi-camera smartphones featuring wide, standard, and telephoto lenses, the zoom experience is often jittery as cameras switch between lenses. The Dimensity 9400 introduces a new smooth zoom experience, comparable to that of a DSLR. It seamlessly transitions through the focal length without abrupt jumps during lens switching, ensuring video capture remains smooth while sustaining autofocus on the intended subject.
Phone-to-phone Ultra-long Reach Connections
Here’s something new: Imagine you need to send a message to a friend, but you have no cellular reception and no satellite connectivity (yet!). Normally, you’d need to find an area with reception. However, now you can establish a direct Bluetooth connection with another Dimensity 9400-powered device up to 1.5 km away—no additional network infrastructure required!
Sonic Sensations
When recording video, the Dimensity 9400 can utilize up to six microphones, enabling them to work together to accurately capture the subject's sound. AI Audio Focus eliminates sudden background noises, unwanted talking, shouting, or even poor singing, making it ideal for streamers, vloggers, and capturing live experiences.
For audiophiles, it also supports high-end Bluetooth wireless headsets and earbuds, offering increased data bandwidth to deliver higher-fidelity audio streams.
Your streams look their best wherever you watch
The Dimensity Adaptive Vision Engine ensures a consistent visual experience across all video content, taking ambient light conditions into account. It interprets the intended viewing experience and actively adjusts screen brightness and color to match it. Whether you’re watching in a brightly lit space or a dark room at night, the experience remains consistent. It supports all SDR and HDR content formats and accommodates a wide range of ambient lighting brightness levels.
More Streams More Speed
The previous Dimensity 9300 was the first smartphone chip to include Wi-Fi 7. In this generation, the Dimensity 9400 has further upgraded wireless performance, achieving speeds of up to 7.3Gbps. This improvement is made possible by a new tri-band concurrent connection that supports five data streams (2x2 + 2x2 + 1x1). Competing platforms, by contrast, can only connect to two bands simultaneously, which limits their speeds.
Ultra-efficient Wireless Combo Chip
MediaTek has once again produced a cutting-edge connectivity superchip. Manufactured using a leading 4nm chip production process, this ultra-efficient Wi-Fi and Bluetooth combo chip reduces power consumption by up to 50% for both connections compared to the previous generation flagship chip, ensuring that even heavy network activity does not adversely affect battery life.
