The processor pairs this powerful CPU with the Arm Mali-G720 MC7 GPU, which promises:

• 24% higher peak performance
• 42% reduced power consumption compared to previous generations
• Enhanced touch latency optimization for smoother responsiveness

Performance Boost Over Dimensity 8300

Compared to its predecessor, the Dimensity 8300, MediaTek claims the 8400 delivers:

• 41% faster multi-core performance
• 44% lower peak power consumption, enabling improved energy efficiency
• Up to 100% more L2 cache, 50% more L3 cache, and 25% more SLC cache, resulting in better data handling and processing speeds

The MediaTek Dimensity 8400 brings cutting-edge features that enhance both display quality and connectivity options. It supports WQHD+ displays with a 144Hz refresh rate, delivering sharper visuals and ultra-smooth scrolling, ideal for gaming and multimedia experiences.

The chipset is equipped with LPDDR5X RAM and UFS 4.0 storage, ensuring faster memory access and improved data transfer speeds. For seamless wireless connectivity, it incorporates support for Wi-Fi 6E and Bluetooth 5.4, enabling faster, more reliable connections with modern devices.

AI Performance

In terms of AI performance, the MediaTek NPU 880 powers the Dimensity 8400, offering 20% faster integer and floating-point calculations for complex tasks. It also provides a 33% boost in large language model text processing, improving AI-driven applications such as voice assistants and predictive text.

Additionally, AI-based image generation performance sees a 21% increase, while operating 18% more efficiently, making it a versatile chipset for both productivity and creative tasks.

For photography and videography, the Imagiq 1080 ISP takes imaging capabilities to the next level. It supports 320 MP camera sensors, enabling ultra-high-resolution photography, and features in-sensor zoom with 100% PDAF (Phase Detection Autofocus) for faster and more accurate focusing.

Users can capture HDR video across the full zoom range, ensuring high-quality output in varying lighting conditions. Moreover, 4K HDR video recording benefits from 12% lower power consumption, delivering longer recording sessions without draining the battery quickly.

5G Connectivity and Modem Upgrades

The Dimensity 8400 also features MediaTek’s 5G-A modem, capable of delivering download speeds of up to 5.17Gbps. This ensures fast and stable connectivity for streaming, gaming, and downloads, making it ideal for modern, high-performance smartphones.

Redmi Turbo 4 to Debut with Dimensity 8400

MediaTek’s Dimensity 8400 will first power the Redmi Turbo 4, which is expected to launch in early 2025. According to a report from GSMArena, this device could be one of the first smartphones to leverage the capabilities of the 8400 SoC, showcasing its speed, AI processing, and camera enhancements.

Is Dimensity 8400 a Snapdragon Killer?

With its advanced CPU and GPU design, energy-efficient performance, and AI-optimized processing, the Dimensity 8400 emerges as a direct competitor to Qualcomm’s Snapdragon 7+ Gen 3, which has long dominated the upper-midrange market.

However, whether it can fully replace Qualcomm’s chipsets will depend on real-world performance tests and user feedback once devices like the Redmi Turbo 4 hit the market. Early signs indicate that the Dimensity 8400 has the potential to set new benchmarks for midrange devices, offering flagship-level features at more accessible price points.
