Unleash the Power: MediaTek Dimensity 9400 vs 9300: What’s New and Why It Matters
What’s New in MediaTek’s 2025 Flagship Chipset? A Breakdown of the Dimensity 9400
MediaTek has lifted the lid on its 2025 flagship mobile chipset, the Dimensity 9400, and it’s packed with exciting upgrades. But how does it compare to last year’s top-end Dimensity 9300?
While the Dimensity 9300 and its overclocked counterpart, the 9300+, delivered impressive performance that bested even Qualcomm’s Snapdragon-powered competition, the new Dimensity 9400 takes it up a notch. More processing power, more AI smarts, more camera features – simply, more.
So, what’s new with this year’s chipset? That’s where we come in. In this article, we’ll dive into the key differences between MediaTek’s latest and greatest, the Dimensity 9400, and its predecessor, the Dimensity 9300.
Performance Boost
The Dimensity 9400 continues MediaTek’s All-Big-Core design introduced with the Dimensity 9300, which uses TSMC’s second-gen 3nm process. The new chipset boasts a solid performance upgrade across the board, with:
- A 35% boost in single-core performance
- A 28% increase in multi-core performance
- An 8th-generation NPU with personalized CPU cores for better performance and power efficiency when running AI tasks
Graphics Enhancements
The GPU takes center stage with a massive 41% boost in peak performance and 40% faster ray-tracing performance, all while being 44% more efficient. Early Geekbench 6 scores of 3055 and 9600 paint a picture of a significantly upgraded chipset, with the overclocked Dimensity 9300+ in the Xiaomi 14T Pro scoring 2226 and 7227 respectively in the same benchmark test.
AGENTIC AI: The Future of On-Device AI
The Dimensity 9400 makes good use of its upgraded NPU, supporting what MediaTek calls ‘Agentic AI’. This is the natural progression for on-device AI capabilities, providing developers and manufacturers with the framework to create AI Agents that handle specific tasks on your device. Think of it as AI agents solving more complex problems by figuring out what needs to be triggered on your device and doing it on your behalf.
Many manufacturers are already taking advantage of Agentic AI in their 9400-equipped devices, so we won’t have to wait long to experience it firsthand.
Connectivity Upgrades
The Dimensity 9400 also boosts connectivity components, featuring:
- 15% faster Wi-Fi connection speeds in busy environments with AI Network Suite 2.0
- Support for Wi-Fi 7 with tri-band support for improved Wi-Fi performance
- UltraSave 4.0 for an 18% reduction in connectivity power consumption
- 24-bit/384KHz Bluetooth audio for improved audio quality
Camera Upgrades
The Dimensity 9400 also focuses on camera performance, boasting an upgraded ISP, Imagiq 1090. New camera features include:
- Full-range HDR Zoom
- Generative AI-powered Super Zoom (similar to Google’s Super Res Zoom tech)
- Boosted 8K@60fps video
- Support for new codecs, including HECV, AVC, VP9, and AV1
- Smooth video zoom with sustained target focus for reduced jitter and maintained focus on the subject
With the Dimensity 9400, MediaTek shows it’s committed to delivering top-notch performance, AI capabilities, and camera performance. We can’t wait to get our hands on devices powered by this impressive chipset to put it to the test.
