TL; DR
- The Dimensity 9400 has been launched with 35% better single-core, 28% multi-core, and 41% GPU boost, along with improved power efficiency by 40%.
- It’s built on TSMC’s 3nm N3E node.
- It supports the Gemini Nano on-device AI model, 8K 60fps video capture, tri-fold display, satellite connectivity, and LLM handling up to 50 tokens per second.
The MediaTek Dimensity 9400 is finally here after months of leaks and anticipation, marking the 4th and latest addition to MediaTek’s flagship SoC lineup. Packed with cutting-edge features, it’s built on ARM’s v9.2 CPU architecture and brings the second-gen All-Big-Core design, featuring one Cortex-X925 core clocked at 3.63 GHz, three Cortex-X4 cores at 3.3 GHz, and four Cortex-A720 cores at 2.4 GHz.
CPU Performance Boosts and New Process Node
Compared to its predecessor, the Dimensity 9300, the 9400 brings a notable 35% improvement in single-core performance and 28% in multi-core performance, thanks to clock boosts and also the new TSMC 2nd generation 3nm N3E process. With this, you’re looking at 40% better efficiency or, in other words, less power draw.

Powerful GPU with Ray Tracing
The 12-core Immortalis T925 GPU pushes the boundaries of performance with a 41% boost in peak performance and 40% faster ray tracing compared to the Dimensity 9300. It also boasts up to 44% power savings during intense gaming sessions.
MediaTek has integrated an AI frame rate converter and HyperEngine’s Super Resolution to further enhance the gaming experience by incorporating more frames and better resolution for the gameplay.
The GPU supports the latest Vulkan and OpenGL benchmarks, showing a 31% improvement in the Aztec Ruins Vulkan 1440p benchmark and a 9% boost in the Manhattan 3.1 1080p benchmark.

AI and Gemini Nano support, Now on MediaTek Dimensity 9400
On the AI side, MediaTek’s new Agentic AI Engine provides 80% faster prompt performance and 100% better performance in diffusion generation. In fact, you can even train LoRA on-device with the Dimensity 9400.
MediaTek also says that it’s the world’s first high-quality on-device video generation. Does this mean you can generate high-quality AI videos on-device on the Dimensity 9400? Probably.
For LLMs (large language models), it can handle up to 50 tokens per second. MediaTek has not specified the size of the LLM, though. For context, the size of the LLM has a huge impact on the number of tokens per second. If a 7B parameter LLM can do 22 tokens per second, a 33B parameter LLM can only do 3-4 tokens per second.
The Dimensity 9400 is also the first non-Tensor mobile chip capable of running the Gemini Nano on-device AI model.

8K60 8-bit Video and Tri-Fold Display Support
Another feature is 8K 60fps (8-bit) video capture, the first of its kind in a smartphone SoC, plus improved power efficiency during 4K60 video recording. The SoC also supports full-range HDR zoom, meaning you can record HDR video while zooming without losing detail or dynamic range. Oh, and the chip also now supports 8K30 10-bit video.
The MediaTek Imageiq 1090 enhances image processing with Generative AI Superzoom, giving you high-quality long-range zoom by using AI to sharpen images. For the display, it supports 180 Hz refresh rate at WQHD+ resolution now. It even has support for tri-fold display now, thanks to the 3x MIPI DSI interface.

The Dimensity 9400 is equipped with a new 5G modem, supporting download speeds of up to 7Gbps in ideal conditions. MediaTek has claimed a 15% improvement in connectivity speeds under challenging network conditions compared to the Dimensity 9300. There’s also an 18% efficiency gain.
For Wi-Fi, the SoC introduces tri-band Wi-Fi concurrency, meaning it can simultaneously use three Wi-Fi bands for faster, more reliable connections. MediaTek’s Xtra Range 3.0 boosts Wi-Fi coverage by 30 meters.
Additionally, the new 4nm Bluetooth/Wi-Fi combo chip is now 50% more efficient and capable of doing phone-to-phone connections up to 1.5km away. It supports Wi-Fi 7, by the way. The Dimensity 9400 also supports satellite connectivity now.

Upcoming Devices with MediaTek Dimensity 9400
You’ll first see the Dimensity 9400 in action in the vivo X200 series, which is set to launch on October 14, 2024, in China. The series includes three smartphones: the vivo X200, vivo X200 Pro, and the vivo X200 Pro mini. There’ll also be a satellite version of the vivo X200 Pro that will take advantage of the satellite connectivity on the MediaTek Dimensity 9400.
This will be followed by the OPPO Find X8 series, which is set to launch on October 24, 2024, also in China. The global launch of the OPPO Find X8 series could be earlier than the vivo X200 series—perhaps next month or December 2024. What are your thoughts on the MediaTek Dimensity 9400?
