MediaTek Adaptive Gaming Technology 3.0
Monitors real-time operating conditions and device status, automatically balancing visual quality and performance to maintain stable frame rates while maximizing battery efficiency. This results in lower power consumption in popular games compared with competing chipsets.
MediaTek’s Network Observation System (NOS)
Strengthens network connectivity and improves power efficiency by enabling accurate 5G and Wi-Fi switching, and applying advanced network prediction techniques.
Support for up to 140MHz of 5G spectrum enables downlink speeds of up to 3.27Gb/s using 3CC carrier aggregation. Combined FDD and TDD duplex support helps deliver faster and more consistent performance in both urban and suburban environments.
In addition, 3CC carrier aggregation allows smoother transitions between 5G coverage areas within the same layer, offering more than 30% greater throughput layer coverage compared to networks without carrier aggregation.
MediaTek 5G UltraSave 3.0+
MediaTek 5G UltraSave 3.0+ integrates delivers up to 20% better power efficiency than competing solutions in typical sub-6GHz 5G usage scenarios.
Scenario-specific enhancements
Second-generation high speed rail mode improves performance by up to 20%, while emerging from areas without coverage receives up to 20% faster 5G recovery time.
Featuring a 12-bit HDR ISP and support for up to 200 MP main cameras, the Imagiq 950 ISP enhances image quality with advanced hardware engines for precise noise reduction (MCNR), face detection (HWFD), and video HDR. It ensures sharp and clear photo and video captures in any lighting conditions.
Google Ultra HDR support further improves the end-to-end HDR photography experience through gain maps that preserve additional light intensity data, resulting in more detailed highlights and shadows with richer, more intense colors.
This highly efficient 4nm-class chip delivers up to 25% greater power efficiency in popular everyday applications than competing alternatives, extending battery life while maintaining strong performance.
MediaTek MiraVision 955 supports highly detailed WFHD+ smartphone displays with 10-bit true HDR color, while the Dimensity 7450X adds exclusive dual-display support for flip phones.
A wide range of global HDR standards is supported for diverse media streaming and playback, delivering a high-quality cinematic experience anywhere.
Smartphone brands can adopt tri-band Wi-Fi 6E to deliver reliable, multi-gigabit wireless performance, with MediaTek UAC technology optimizes antenna behavior based on device orientation and user proximity.
MediaTek Lightning Connect doubles Bluetooth connection speeds, while Wi-Fi / Bluetooth hybrid coexistence ensures smooth, low-latency BT connections with peripherals such as earbuds and gamepads.
