MediaTek has announced the launch of its Dimensity 9400e flagship processor, which also adopts an all-big-core architecture. It is expected to be a slightly upgraded version of the Dimensity 9300+ and will compete with Qualcomm's Snapdragon 8s Gen 4. It is expected to be first used in OnePlus' new mobile phone Ace 5 Racing.
天璣9400e採用台積電第三代4nm製程設計，全大核CPU架構包含4組Cortex-X4超大核，主頻高達3.4GHz，加上額外4組主頻為2.0GHz的Cortex-A720大核，形成「4+4」的核心配置，另外則搭載旗艦12核Immortalis-G720 GPU，支援硬體光線追蹤技術與PC等級的全域光照效果。
In addition, with the Dimensity Star Speed Engine supporting Adaptive Control Technology 2.0, MediaTek claims that it can perform real-time performance scheduling between the processor and gaming applications, allowing games to run with stable FPS and lower power consumption. The Dimensity 9400e also supports MFRC 2.0+ (MediaTek Frame Rate Converter 2.0+) technology, which will save 40% power consumption when enabled.
The Dimensity 9400e supports the latest generation of the Dimensity AI Development Kit (NeuroPilot SDK) and is equipped with enhanced Speculative Decoding+ (SpD+) technology, which can accelerate the computing efficiency of large language models. It also supports the world's mainstream large and small language models, and supports the device-side operation of models such as DeepSeek-R1-Distill, Qwen1.5B, Llama7B, Llama8B, as well as multimodal Gemini Nano, LlaVA-1.5 7B, etc.
The Dimensity 9400e is also equipped with a flagship 18-bit RAW image processor and supports an AI image semantic segmentation engine that can perform 16-layer image semantic segmentation. It also supports high-dynamic recording noise reduction with three sets of microphones. Other features include support for extending the phone-to-phone Bluetooth connection distance within line of sight to 3 kilometers, supporting Sub-5GHz four-carrier aggregation with a theoretical peak downlink rate of 7Gbps, and Wi-Fi 6 connectivity with a theoretical peak transmission rate of 7.3Gbps, tri-band multi-link operation (MLO), and five data streams.
此次同步更新符合R18 5G-Advanced、搭載聯發科M90 5G數據晶片、四核Arm Cortex-A55 CPU、網路處理器，可全速處理5G、Wi-Fi、乙太網路連接的T930數據平台，本身以4nm製程生產，支援Sub-6GHz頻段，並且提供高達10Gbps的5G連網速度，另外也支援下行6載波聚合、上行5層3天線傳輸，上行速率最高可達2.8Gbps，下行傳輸則可支援200MHz頻寬，可在小型基地台邊緣連線時有效增加40%的訊號覆蓋範圍。
In addition, the T930 data platform can also be combined with the NPU to create a generative AI gateway (GenAI Gateway), which can provide advanced edge artificial intelligence computing and interactive functions on edge devices within the network domain.
