Earlier this week, a report hinted that MediaTek's next Dimensity 8400 SoC could use an all-big-core setup, similar to the more robust Dimensity 9400. Now, it appears that this rumor may hold some truth, based on a new insight from tech insider Digital Chat Station (DCS).
CPU Architecture Insights
Today, DCS revealed information regarding the CPU structure of the new SoC, indicating a core design packed with ARM’s high-performance cores. The Dimensity 8400 is expected to come equipped with an octa-core CPU featuring a 1+3+4 configuration, manufactured on TSMC’s 4nm process. Central to its performance is the ARM Cortex-A725 core, which is clocked at over 3GHz.
Core Configuration
Interestingly, it’s not just a single Cortex-A725 in this setup; MediaTek is reportedly bringing in three additional cores, each running slightly under 3GHz but still close to the primary core's speed. For lighter workloads, MediaTek is said to be using three ARM Cortex-A720 cores, which are regarded as “premium efficiency” cores. This is a significant improvement from the Cortex-A510 cores utilized in the Dimensity 8300. These A720 cores are expected to function efficiently around the 2.0GHz range, making them suitable for everyday tasks. Even the Dimensity 9400 uses these cores.
Graphics and Performance
On the graphics side, the Dimensity 8400 is likely to have some familiar features. It is rumored that the chip will incorporate the same GPU IP – the Arm Immortalis-G925 – as found in its more powerful counterpart, the Dimensity 9400. Whether it will maintain the same number of cores is still unknown. DCS also noted that the performance of the chipset is still being optimized, which means that the final clock speeds and performance metrics could still change.
At this point, it’s uncertain which smartphone will be the first to utilize the Dimensity 8400. However, speculation suggests it may appear in either the upcoming Redmi K80 series or Oppo’s Reno 13 lineup. We can anticipate more information about these devices, along with the final specifications of the Dimensity 8400, to emerge in the upcoming weeks. We will keep you posted on these developments.
