Exploring the MediaTek Dimensity 8400: A Mid-Range Chipset with Flagship DNA?
In a surprising move for the mid-range smartphone market, MediaTek is set to introduce the Dimensity 8400, a chipset that boasts similarities to its flagship sibling, the Dimensity 9400, launched in October 2024.
This article will explore the key features and potential impact of the Dimensity 8400, particularly its unique “all-big-core” configuration, which is rare in mid-range processors.
Dimensity 8400: Performance-Oriented, Without Efficiency Cores
The Dimensity 8400 mirrors some key aspects of the Dimensity 9400. One standout feature is its pure focus on performance cores, with no energy-efficient cores in its configuration. According to information from the well-known Weibo tipster, Digital Chat Station, the Dimensity 8400’s CPU layout will follow a "1+3+4" format, featuring eight Cortex-A725 cores.
The main prime Cortex-A725 core will clock at 3.0 GHz, supported by three more Cortex-A725 cores at the same speed. Meanwhile, the remaining four Cortex-A725 cores will be set at a reduced clock speed of 2.0 GHz, although the final frequencies are still under consideration as MediaTek fine-tunes for an optimal balance of performance and power efficiency.
This all-performance-core setup means the Dimensity 8400 lacks efficiency-focused cores, such as Cortex A5x series cores. However, unlike the Dimensity 9400, it doesn’t include the high-powered Cortex-X925 or X4 cores commonly found in flagship processors. This streamlined configuration appears to aim for an optimized balance of mid-range pricing with solid performance.
Immortalis-G925 GPU: A Flagship Graphic Experience with a Twist
In addition to CPU performance, the Dimensity 8400 will include a GPU with impressive capabilities, aligning with the flagship Immortalis-G925 found in the Dimensity 9400. However, industry sources suggest that while the GPU may retain the same architecture, it will likely be dialed down with lower clock speeds and fewer cores.
This adjusted configuration is expected to deliver robust graphics for the mid-range sector, though without the peak performance of its flagship counterpart.
The Immortalis-G925 GPU is known for enhanced efficiency and a 37% performance boost compared to its predecessor, the Immortalis-G720, as well as improved ray-tracing capabilities by 52%. This makes it well-suited to handle modern mobile gaming and graphic-intensive tasks even in a mid-range device.
The Benefits and Challenges of an All-Big-Core Approach
MediaTek’s decision to exclude efficiency cores in mid-range processors reflects a broader trend that began with the Dimensity 9300 and Snapdragon 8 Gen 3 in 2023.
While an all-big-core configuration has clear performance advantages, some concerns about potential overheating and battery drain may arise.
However, according to MediaTek’s Finbar Moynihan, the absence of efficiency cores in the Dimensity 9300 actually helps optimize battery life by allowing powerful cores to complete tasks faster, shutting down sooner to save power and reduce heat. This philosophy could also apply to the Dimensity 8400, offering a high-performance experience without compromising too heavily on power efficiency.
Production Details and Expectations
To manage potential heat and power challenges, the Dimensity 8400 will reportedly be built on TSMC’s 4nm manufacturing process, the same used for the flagship Dimensity 9300. This advanced production technology should enhance the chipset's efficiency and thermal management, making it a competitive choice for mid-range smartphones.

Final Thoughts
With the Dimensity 8400, MediaTek appears poised to push the boundaries of mid-range mobile processing by delivering a performance-focused experience previously reserved for flagship devices.
By incorporating elements from the Dimensity 9400 while fine-tuning for the mid-range segment, MediaTek offers an exciting alternative for consumers looking for high performance without the flagship price tag.
The unique “all-big-core” architecture, combined with the capable Immortalis-G925 GPU, ensures that the Dimensity 8400 is more than just a budget-friendly chipset; it's a performance-oriented powerhouse that could redefine expectations in the mid-range smartphone market.
