MediaTek appears to be pushing boundaries in the mid-range processor segment with its upcoming Dimensity 8400 chipset, adopting an innovative all-performance core approach similar to its flagship counterpart.
Architecture and Core Configuration
The Dimensity 8400 is set to feature an octa-core CPU with a 1+3+4 configuration, built on TSMC's advanced 4nm N4P process. At its heart lies a primary Cortex-A725 core, capable of reaching speeds up to 3.0GHz. Supporting this are three additional Cortex-A725 cores also running at 3.0GHz, creating a powerful performance cluster. The remaining four cores are also Cortex-A725, operating at a more modest 2.0GHz for improved efficiency.
Graphics Capabilities
The GPU implementation in the Dimensity 8400 shares DNA with its more premium sibling, the Dimensity 9400. According to Digital Chat Station, the chipset will utilize the same GPU IP, suggesting the implementation of ARM's Immortalis-G925. However, it's expected to operate at lower clock speeds and with fewer GPU cores to maintain an appropriate performance-to-power ratio for its market positioning.
Manufacturing Process and Efficiency
TSMC's 4nm N4P architecture, the same process used in the Dimensity 9300 and 9300+, will serve as the foundation for the 8400. This manufacturing process should help MediaTek achieve an optimal balance between performance and power efficiency, crucial for maintaining competitive thermal characteristics despite the all-performance core design.
Market Positioning and Future Implementation
While the official announcement is still pending, industry speculation suggests that the Dimensity 8400 might debut in either the upcoming Redmi K80 series or Oppo's Reno 13 lineup. The chipset's final specifications and clock speeds are still under optimization, indicating MediaTek's commitment to refining the platform before its market release.
