MediaTek Dimensity 8400 now official with all big core CPU, a first for its segment | Infinium-tech

MediaTek’s Dimensity 9300 launched last year was the first Android SoC to go with an all big core configuration for its CPU, this year’s Dimensity 9400 also came with it, but they are both top chipsets.

Today marks the debut of the first upper-midrange SoC with a full big core CPU. Meet the MediaTek Dimensity 8400, which will definitely pose a major threat in terms of performance to the Qualcomm Snapdragon 7+ Gen 3, which has been the uncontested king of this category for some time now.

The Dimensity 8400 comes with eight Cortex-A725 CPU cores clocked at 3.25 GHz. Note that although MediaTek has not reduced the clock speed per core, this is likely to be achieved only by one of them, not all.

Compared to the Dimensity 8300, MediaTek claims a 41% improvement in multi-core performance. The company claims 44% less peak power usage, 100% more L2 cache, 50% more L3 cache, and 25% more SLC cache. The chip supports WQHD+ screen at 144Hz refresh rate, LPDDR5X RAM and UFS 4.0 storage, Wi-Fi 6E, and Bluetooth 5.4.

The CPU is paired with an Arm Mali-G720 MC7 GPU, which brings 24% higher peak performance and 42% lower power usage. You can also expect touch latency optimization. The MediaTek NPU 880 in the Dimensity 8400 is 20% faster in integer/floating-point operations (33% in large language model text generation), improves efficiency by 18%, and is also 21% better in static expansion 1.5.

The SoC features an Imagick 1080 ISP that supports a 320MP sensor, 100% in-sensor zoom with PDAF, HDR video recording across the entire zoom range, and it uses 12% less power in 4K HDR video capture. Finally, the new 5G-A modem comes with 5.17Gbps download performance.
