Dimensity 6400
Fantastic selfies, fun gaming and faster 5G


MediaTek Dimensity 5G Family
The MediaTek Dimensity 6400 empowers mainstream smartphones with faster 5G performance, with support for large cameras sensors and impressive true color AMOLED displays, and smooth gaming experiences with MediaTek HyperEngine.
Smooth Gaming
with MediaTek HyperEngine
MediaTek HyperEngine ensures that games and user interfaces run smoothly while being exceptionally power-efficient. Compared to competing alternatives, power consumption during gaming can be up to 19% lower, enhancing battery life.
Additionally, 5G call and data concurrency, which predicts connection quality based on real-time conditions, ensures that gamers always stay connected.
Additional Key Features
MediaTek's Wi-Fi and Bluetooth coexistence technology ensures simultaneous operation on the 2.4 GHz band without interference, always maintaining reliable network and peripheral connectivity.
Pre-integrated multiframe noise reduction (MFNR) and low-power noise reduction (LPNR) with facial awareness enhancements ensure that selfies and portrait photos always look their best.
Smartphone designers can integrate cameras with resolutions of up to 108MP to deliver incredibly detailed photos, while also offering advanced video capabilities.
Experience contour-free, true-to-life colors with AMOLED HDR displays. These displays offer Full HD+ resolution at 120Hz with 10-bit color support, enhanced further by 3D ULT technology. The Dimensity 6400 empowers smartphone designers to incorporate stunning displays that truly stand out.
The Dimensity 6400 incorporates a 3GPP Release-16 compliant 5G modem, featuring the latest connectivity enhancements adopted by global cellular operators. This allows device designers to create a single smartphone design for worldwide markets, significantly reducing costs and accelerating global rollouts.
5G up to 3.3Gbps
Support for up to 140MHz cellular spectrum, the Dimensity chipset delivers up to 3.3Gbps 5G downlink speeds via 2CC carrier aggregation (CA). This enables up to 40% faster speeds in urban areas and up to 30% faster in suburban environments compared to competitor solutions.
Its carrier aggregation technology allows mixed duplex FDD+TDD combinations, combining low-band and mid-band advantages for faster speeds and extended reach. Seamless handovers between two 5G coverage areas ensure over 30% better throughput and coverage compared to non-CA solutions.
MediaTek 5G UltraSave 3.0+
MediaTek 5G UltraSave 3.0+ includes a full suite of Release-16 power-saving enhancements, combined with MediaTek’s proprietary optimizations. This results in 13–30% greater power efficiency compared to competitor solutions in common 5G sub-6GHz connectivity scenarios.
Situationally Intelligent Enhancements
MediaTek’s 5G modem is designed to adapt to challenging environments, such as high-speed rail, subways, or underground vehicle travel. These situationally intelligent enhancements deliver 20% more effective downlink speeds compared to competitor solutions.
LB+LB ENDC and 8-Layer DL MIMO Support
Support for dual low-band ENDC (E-UTRA-NR Dual Connectivity) and 8-layer DL MIMO ensures compatibility with the latest cellular operator requirements, providing a future-proof solution for smartphones.
