AI is becoming an integral part of how we interact with our devices, and it only truly becomes useful if the vast majority of phones can take advantage of those models. The Dimensity 7400 series from MediaTek offers a better dedicated NPU and heavy improvements to gaming at its level.
The Dimensity 7400 and 7400X are both brand-new from MediaTek. Where the existing Dimensity 9400 and 8400 are obtainable in high-end smartphones, the 7400 series will likely sit in the high to middle range of devices. MediaTek is also announcing the Dimensity 6400, which will sit below that and bring some of its own improvements to the market as a whole.
The Dimensity 7400 and 7400X bring an octa-core CPU with four Arm cortex-A78 and four Cortex-A55 cores. The structure also has room for a Mali-G615 MC2 GPU, which comes into play where the chips supposedly shine. Both SoCs are built on a 4nm process and boast power efficiency while gaming.
MediaTek is utilizing a proprietary 6th-gen NPU. According to MediaTek, its performance is 15% better than the 7300’s. If that’s true, that’s a big jump in AI, considering that there tend to be diminishing returns after a certain point. This positions the Dimensity 7400 series as a contender for mid-range devices that bring AI to more users beyond just the high-end flagships.
There seem to be a couple of differences between the 7400 and 7400X. The 7400X is compatible with dual-display flip devices. Beyond that, the two SoCs are very similar.
MediaTek’s Dimesnity 6400 is also an important release. It has half the number of Cortex-A76 cores and two more A55 cores, which offers decent performance at a lower cost. The phones it finds itself in are likely going to be budget devices that aim to offer users the essentials. The SoC prioritizes 5G connectivity and some gaming.
MediaTek notes that the Dimensity 7400 and 7400X will be found in devices starting in Q1 2025, while the Dimensity 6400 is now available.
