MediaTek has recently introduced its latest upper mid-range mobile processor, the Dimensity 8400. This new processor boasts an all big core CPU design, mirroring the architecture of the flagship Dimensity 9400 found in the Oppo Find X8 Series and Vivo X200 Series.
The Dimensity 8400 features eight Cortex-A725 CPU cores, clocked up to 3.25 GHz. It’s important to note that it’s most likely only one core can achieve this maximum speed.
According to MediaTek, the Dimensity 8400 offers a 41% improvement in multi-core performance compared to its predecessor, the Dimensity 8300.
The company also highlights a 44% reduction in peak power usage, an increase of up to 100% in L2 cache, 50% more L3 cache, and a 25% increase in SLC cache.
The processor supports WQHD+ screens with refresh rates up to 144 Hz, LPDDR5X RAM, UFS 4.0 storage, Wi-Fi 6E, and Bluetooth 5.4.
Accompanying the CPU is the Arm Mali-G720 MC7 GPU, which delivers 24% higher peak performance while consuming 42% less power. Users can also anticipate improved touch latency optimisations.
The MediaTek NPU 880, integrated into the Dimensity 8400, is 20% faster in integer/floating-point operations, with a 33% boost in large language model text generation, 18% efficiency improvement, and a 21% enhancement in Stable Diffusion 1.5.
Additionally, the system-on-chip (SoC) includes the Imagiq 1080 ISP, which supports 320 MP sensors, in-sensor zoom with 100% PDAF, HDR video recording across the entire zoom range, and a 12% reduction in power consumption during 4K HDR video capture. The new 5G-A modem offers download speeds of up to 5.17 Gbps.
Poco and Realme upcoming phones are using this chip
The Poco X7 Pro is expected to be the world’s first smartphone to use the Dimensity 8400, while the Realme Neo7 SE, which is launching in China early next year, is also using the same chip.
