Last year, MediaTek released the Dimensity 9300 mobile processor, the first SoC for Android devices to feature a CPU configuration exclusively made up of large cores. This year’s Dimensity 9400 chip also followed suit. And now MediaTek has announced the new Dimensity 8400 processor, the first member of the upper mid-range class with a CPU consisting only of large cores. The new product will compete with Qualcomm Snapdragon 7+ Gen 3, which has been the undisputed leader in this category for quite some time.
The MediaTek Dimensity 8400 processor is equipped with eight Cortex-A725 cores with clock speeds up to 3.25 GHz. Although MediaTek did not provide a breakdown of the clock speed by core, it is likely that only one of them will reach this frequency, not all of them.
Compared to the Dimensity 8300, MediaTek claims a 41% improvement in multi-core performance. At the same time, the company boasts 44% lower peak power consumption, up to 100% larger L2 cache, 50% larger L3 cache, and 25% larger SLC cache. The chip supports screens with resolutions up to WQHD+ with refresh rates up to 144 Hz, LPDDR5X RAM and UFS 4.0 storage, as well as Wi-Fi 6E and Bluetooth 5.4 wireless interfaces.
The computing cores are paired with the Arm Mali-G720 MC7 GPU, which provides 24% higher peak performance and 42% lower power consumption. The manufacturer also promises optimized touch input latency. The MediaTek NPU 880 found in Dimensity 8400 is 20% faster in integer/floating point operations (33% faster in large language model text generation), 18% better in efficiency, and 21% better in Stable Diffusion 1.5.
The SoC features the Imagiq 1080 ISP, which supports 320-megapixel sensors, in-sensor zoom with 100% PDAF, HDR video recording across the entire zoom range, and uses 12% less power when recording 4K HDR video. Finally, the new 5G-A modem provides download speeds of up to 5.17 Gbps.
Smartphones based on the MediaTek Dimensity 8400 processor are expected to hit the market early next year. The first device with this chip is Redmi Turbo 4.
