MediaTek Dimensity 8450

MediaTek Dimensity 8450

Dimensity 8450 is a sub-flagship SoC in MediaTek’s lineup, positioned above the 83xx family and below the 94xx. In daily use it feels quick and predictable: snappy UI, smooth animations, and stable battery behavior. Phones with this chip stay cool in messengers, maps, and camera tasks, and run cooler than typical mid-range devices in games.

Under sustained load the behavior stays even. Switching between heavy apps does not tear animations, and background activity does not stall scrolling. Cellular performance is steady in urban conditions, with no surprises in power draw.

Architecture and CPU performance

Eight Arm Cortex-A725 cores in a 1+3+4 layout. The single “big” core handles peak single-threaded spikes. Three cores cover most interactive workloads. Four cores run background tasks and save power. A sizable cache system for the class helps keep responsiveness under growing load. In long multi-threaded runs frequencies step down gradually without sharp drops, so performance feels consistent.

Graphics and multimedia

Arm Mali-G720 MC7 renders a fluid UI on high-refresh displays and runs popular games at high presets with sensible settings. The video pipeline supports 4K at 60 fps recording. Day-to-day shooting benefits from cleaner shadows and stable exposure, and night scenes are handled carefully.

Memory and storage

Supports LPDDR5X up to 8533 MT/s and UFS 4 with MCQ. This shortens cold app starts, speeds up returning apps from memory, and reduces wait times when loading large games. Simultaneous capture, navigation, and cloud sync do not freeze the interface.

Cameras and video

The Imagiq 1080 ISP works with sensors up to 320 MP and allows 3×32 MP at 30 fps configurations. Video recording up to 4K60. In practice you get fast focus, reliable HDR behavior, and stable exposure without “breathing”.

Connectivity and networks

Built-in 5G-Advanced modem with carrier aggregation delivers peak downlink up to 5.17 Gbps and robust performance in challenging areas. Wireless interfaces include Wi-Fi 6E in 2T2R configuration and Bluetooth 5.4. Navigation supports GPS, GLONASS, BeiDou, Galileo, QZSS, and NavIC.

AI acceleration and on-device scenarios

The MediaTek NPU 880 accelerates portrait effects in the camera, improves noise suppression in calls, and runs speech recognition and translation on device. Local models start quickly and work without an internet connection.

Gaming and FPS stability

During long sessions the SoC reduces clocks smoothly. Frame time stays even without dips or stutter. The system prefers a steady high refresh rate in the UI, so gestures and scrolling remain consistently fluid from the first minutes to half an hour into a game.

Conclusion

Dimensity 8450 is for users who want flagship-level responsiveness without a flagship price. Modern CPU cores, Mali-G720 MC7, LPDDR5X and UFS 4, an advanced camera pipeline, and 5G-Advanced add up to a daily experience that feels fast and stable.
