All-in on Performance Cores
Unlike its predecessor, the Dimensity 8300, which utilized a hybrid architecture of Arm Cortex-A715 and A510 cores, the Dimensity 8400 adopts a configuration of eight next-generation Arm Cortex-A725 cores in a 1+3+4 arrangement, mirroring the design of its flagship counterpart, the Dimensity 9400. This shift signifies a move towards prioritizing performance over pure efficiency.
Enhanced Cache and Next-Gen GPU
The Dimensity 8400 boasts a prime core clocking in at an impressive 3.25 GHz. Furthermore, the L3 cache has been increased by 50% to 6MB, enabling faster data retrieval and contributing to a more responsive user experience. L2 and SLC cache also see up to a 100% capacity boost. On the graphics front, the new Arm Mali-G720 MC7 GPU supports 4K 60fps encoding, promising a significant improvement in visual performance.
Performance and Efficiency Gains
MediaTek claims substantial performance improvements with the Dimensity 8400. Multi-core performance is reportedly up by 41% compared to the Dimensity 8300, while power consumption at peak performance is down by 44%. The new GPU delivers a 24% performance increase and a 40% improvement in energy efficiency. The integrated 5G modem also receives an upgrade, supporting peak download speeds of up to 5.71 Gbps.

Upgraded AI Capabilities
The Dimensity 8400 incorporates a revamped AI accelerator and integrates MediaTek’s Dimensity Agentic AI Engine (DAE), previously exclusive to flagship chipsets. This enhancement results in a 20% increase in AI processing speed and image generation, up to a 33% improvement in AI text generation, and an 18% boost in AI efficiency.
Impressive Imaging Capabilities
The Imagiq 1080 ISP offers advanced camera features, including HDR video recording across the entire zoom range, 4K 60fps video capture, in-sensor zoom with 100% phase detection auto-focus (PDAF), and 320MP composite image capture. This makes the Dimensity 8400 an attractive option for users seeking high-quality mobile photography without the premium price tag.
Availability and Future Developments
The first smartphones powered by the Dimensity 8400 are expected to launch by the end of the year. Xiaomi has also announced plans to release a Redmi Turbo device featuring a slightly enhanced version, the Dimensity 8400 Ultra, in China early next year.
Conclusion
The MediaTek Dimensity 8400 represents a significant leap forward in mid-range mobile processing power. With its focus on performance cores, enhanced GPU, improved AI capabilities, and advanced imaging features, it promises to elevate the user experience for mid-range smartphones. The competitive landscape of mobile processors is heating up, and the Dimensity 8400 is set to make a significant impact.
