MediaTek has officially introduced an enhanced version of its well-received Dimensity 9400 chip, dubbed the Dimensity 9400+. This upgrade includes significant improvements that aspire to elevate the capabilities of MediaTek’s flagship chipset.
The creation of the Dimensity 9400+ stems from MediaTek’s ambition to integrate AI support into its primary chipset. The new chip boasts compatibility with numerous large language models (LLMs), including Mixture-of-Experts (MoE), Multi-Head Latent Attention (MKA), and Multi-Token Prediction (MTP).
Notably, the Dimensity 9400+ also supports FP8 inferencing, resulting in quicker reasoning capabilities. Powered by the MediaTek NPU 890, this iteration aims to deliver a 20% boost in AI performance through Speculative Decoding+ (SpD+), alongside support for the Deepseek-R1-Distill model for on-device processing.
The design of the Dimensity 9400+ mirrors that of its predecessor, featuring an All Big Core configuration. This includes one Arm Cortex-X925 core running at 3.73 GHz, complemented by three Cortex-X4 cores and four Cortex-A720 cores.
In contrast, the original Dimensity 9400 was clocked at 3.62 GHz with the same core lineup. Additionally, the same 12-core Arm Immortalis-G925 GPU is present, enhanced by a new frame rate converter 2.0+ (MFRC 2.0+) that effectively doubles frame rates and improves power efficiency by 40%.
Other notable advancements include an extension of phone-to-phone Bluetooth connections up to 10 km, a BeiDou satellite connection for faster TTFF, Wi-Fi 7 tri-band concurrency with five streams, and enhanced Wi-Fi coverage through MediaTek Xtra Range 3.0. The first smartphone featuring the Dimensity 9400+ is expected to hit the market by the end of the month, with Oppo’s Find X8 series likely to be the initial beneficiary of this advanced chipset.
