It is rumored that the Dimensity 9400 will use TSMC’s 3nm process and its performance will be greatly improved.

There have been many rumors that the Dimensity 9400 mobile platform and the fourth-generation Snapdragon 8 mobile platform will become the first Android lineup flagship SoC using the 3nm process node. Recently, blogger Digital Chat Station revealed that MediaTek plans to use TSMC’s second-generation 3nm process to manufacture the next-generation flagship SoC, and the blog post mentioned that the performance of this SoC is super strong.

Last year, TSMC's 3nm production line had only one customer: Apple. Apple's A17Pro and the entire M3 series of chips were manufactured using TSMC's "N3B" process, which is also considered the first generation of 3nm technology. Digital Chat Station mentioned in a blog post that the Dimensity 9400 mobile platform will use TSMC’s second-generation 3nm process. In this regard, wccftech speculates that this process is TSMC's "N3E" lithography process. It is said that this process has a higher wafer output than N3B and a more reasonable price, so it has received orders from Qualcomm and MediaTek. We have also reported before that MediaTek CEO Cai Lixing said that MediaTek is in-depth cooperation with TSMC on a new generation of 3nm chips, and the project is currently being advanced, but he has not revealed too many technical details yet.

In addition, the blog post also mentioned that the Dimensity 9400 mobile platform will use ARM’s latest public version of the CPU and GPU architecture, so MediaTek’s flagship SoC will most likely be equipped with the Cortex-X5 core. The blog post also mentioned that the performance of this SoC is very strong. It has also been reported before that it will have the same architecture as the Dimensity 9300 mobile platform and will not be equipped with an energy efficiency core.

There are even rumors on the Internet that the overall performance of the Dimensity 9400 mobile platform will be stronger than the fourth-generation Snapdragon 8 mobile platform. However, given that Snapdragon will switch to a customized Oryon core this year, the performance difference between the two SoCs cannot be concluded yet.
