On the morning of the 11th, MediaTek officially unveiled the Dimensity 9400+ flagship 5G intelligent AI mobile chip at the MediaTek Dimensity Developer Conference 2025. As a new member of the Dimensity flagship family, it is another breakthrough upgrade after the release of Dimensity 9400 in October last year.
This time, the Dimensity 9400+ adopts the second-generation all-large core architecture. The 8-core CPU includes 1 Arm Cortex-X925 super-large core with a main frequency of up to 3.73GHz, 3 Cortex-X4 super-large cores and 4 Cortex-A720 large cores. The powerful core configuration can provide single-threaded and multi-threaded task processing performance, providing Android device users with a top-level experience.
At the same time, the Dimensity 9400+ focuses on high-intelligence, high-performance, high-efficiency and low-power AI capabilities. By integrating MediaTek's eighth-generation AI processor NPU 890, it supports the world's wide range of large language models, mixed expert models (MoE), multi-head potential attention mechanisms (MLA), multi-Token prediction (MTP) and other AI technologies, as well as enhanced reasoning decoding technology (SpD+) and Dimensity AI intelligent agentic AI Engine, to achieve the intelligentization of AI applications.
MediaTek Vice President Xu Jingquan said that Dimensity 9400+ has further evolved the edge AI capabilities of mobile devices, enabling thousands of applications to have more innovative and personalized AI usage experiences, while the overall enhanced performance can efficiently handle various tasks.
In terms of communication, Dimensity 9400+ brings the following upgrades:
The Bluetooth connection distance between mobile phones within line of sight is extended to 10 kilometers, which is 6.6 times that of Dimensity 9400.
Added support for Beidou satellite orbit information, even without cellular network connection, the first positioning time (TTFF) can be accelerated by 33%.
Supports Wi-Fi 7 tri-band concurrency and supports 5 data streams.
Supports MediaTek Xtra Range™ 3.0 technology, and the Wi-Fi signal coverage can be extended to 30 meters.
5G/4G multi-standard dual-card dual-pass, dual data transmission, providing more flexibility for user selection.
Bluetooth connection extended by 10 kilometers
Compared with the previous Dimensity 9400's 1500-meter Bluetooth connection limit distance, the Dimensity 9400+ has once again focused on improving Bluetooth technology, and this time it has increased by 6.6 times, reaching a connection distance of 10 kilometers between mobile phones within line of sight.
This upgrade still uses the dual Bluetooth fusion technology based on BLR 125Kbps. The dual Bluetooth module effectively expands the connection range of Bluetooth devices and maintains the stability of signal connection and transmission; it also performs well in data transmission rate, significantly speeding up the transmission efficiency of large files; in addition, it also supports simultaneous connection of multiple devices, enhances cross-platform compatibility and scalability, realizes multi-function parallel processing, and significantly improves ease of use and efficiency.
With the development of the Internet of Things, more and more devices need to connect and communicate via Bluetooth. The long-distance Bluetooth connection function of the Dimensity 9400+ can provide IoT devices with a wider connection range and applications in different fields.
In the smart home scenario, using Bluetooth to control smart home systems has become popular, and the distance upgrade brings users a better user experience.
In terms of industrial applications, the long-distance Bluetooth connection function of Dimensity 9400+ enables real-time monitoring and control of personnel and equipment in factory workshops.
The first batch of smartphones equipped with Dimensity 9400+ will be launched this month
The Dimensity 9400+ will be first equipped by the OPPO Find X8s series, bringing a 20% increase in CPU performance, a 15% increase in thermal conductivity, and a 20% increase in AI reasoning capabilities to the series, making it the Android flagship phone with the most comprehensive and best performance in terms of end-side AI model support on the market. It will be officially launched on April 16.
Subsequent terminal new products such as vivo X200s, realme GT7, REDMI K80 Extreme Edition will also be launched one after another this month.
