MediaTek simply introduced the Dimensity 8400 cellular processor. Following a current pattern in flagship SoCs, the brand new chip is powered solely by high-performance cores, with out the smaller effectivity cores. Exterior the CPU, the brand new chip additionally brings flagship options to gaming, images, and, in fact, synthetic intelligence.
After pioneering an all “huge core” format processor in 2023 and repeating the technique with the Dimensity 9400 this yr, MediaTek doubled (tripled?) down on the plan with the brand new mid-range chip: The Dimensity 8400. The brand new chip guarantees extra efficiency for each day duties, with an estimated 41% uplift in multi-core CPU efficiency.

As a substitute of utilizing the smaller (and slower) effectivity CPU cores, MediaTek designed the Dimensity 8400 with an all “huge core” design. The chip options eight ARM Cortex-A725 at as much as 3.25 GHz. These A725 cores are divided into three tiers, with completely different quantities of L2 cache reminiscence: 1 core with 1 MB, 3 cores with 512 KB, and 4 cores with 256 KB.
To feed these cores, the Dimensity 8400 helps the most recent LPDDR5x-8533 RAM customary, whereas storage duties are dealt with by the latest-generation UFS 4 customary.
For graphics rendering, the Dimensity 8400 packs 7 ARM Mali-G720 GPU cores. MediaTek touts 24% higher efficiency and 42% higher energy effectivity in comparison with the earlier technology Dimensity 8300 chip. Whereas the GPU doesn’t help ray tracing, the Taiwanese firm guarantees easy rasterization efficiency.
In true 2024 vogue, the brand new MediaTek mid-ranger helps main AI apps because of its NPU, with promised help for agentic functions. Different cores on the Dimensity 8400 trickle-down options discovered on the flagship 9000 collection, akin to improved processing for picture seize, dynamic 5G/Wi-Fi switching, and extra.
In keeping with MediaTek, the brand new Dimensity 8400 ought to come to market quickly, with the primary telephones promised “by [the] finish of 2024”. Will probably be fascinating to see whether or not Qualcomm will undertake an identical “huge core” design for its Snapdragon 7 chips.
