Add MobiGyaan as a preferred source on GoogleMediaTek has introduced the Dimensity 7450 and Dimensity 7450X, expanding its 7000-series lineup. These new chipsets succeed the Dimensity 7400 and bring incremental improvements in AI performance, connectivity, and efficiency, while retaining a similar CPU architecture. The 7450X variant is specifically optimized for flip-style foldable smartphones, including support for dual displays.
CPU, GPU, & Core Architecture
Both chipsets feature an octa-core configuration:
- 4× Arm Cortex-A78 cores (up to 2.6GHz)
- 4× Arm Cortex-A55 cores
- GPU: Arm Mali-G615 MC2
- Fabrication: 4nm-class process
Compared to the previous generation, the CPU setup remains unchanged, focusing instead on efficiency tuning and AI enhancements.
AI and Imaging Improvements
The new chips integrate a 6th-generation MediaTek NPU, delivering:
- Up to 7% improvement in AI tasks
- Better computational photography performance
- Enhanced AI-based imaging and processing
Camera Capabilities:
- Support for up to 200 MP sensors
- Powered by Imagiq 950 ISP (12-bit HDR)
- 4K video recording at 30fps with HDR and EIS
5G Connectivity and Networking
A key upgrade comes in the form of a 3GPP Release 17 (R17) 5G modem, replacing the R16 modem used in its predecessor.
Key Connectivity Features:
- Support for SA and NSA 5G modes
- Sub-6GHz spectrum compatibility
- Mixed FDD + TDD duplexing
Performance:
- Up to 3.27 Gbps peak download speeds

Efficiency and Stability:
- MediaTek 5G UltraSave 3.0+ (up to 20% better power efficiency)
- Improved high-speed rail mode (+20% performance in transit)
- Faster recovery from network dead zones
Local Connectivity and Smart Networking
- Tri-band Wi-Fi 6E (2T2R antenna)
- Bluetooth 5.4
- MediaTek Network Observation System (NOS) for intelligent switching between Wi-Fi and 5G
Memory, Storage, & Display Support
- Memory: LPDDR5 / LPDDR4x (up to 6,400 Mbps)
- Storage: UFS 3.1 / UFS 2.2
- Display: WFHD+ at 120 Hz / Full HD+ at 144 Hz
The Dimensity 7450 is aimed at upper mid-range smartphones, while the Dimensity 7450X targets flip-style foldables, continuing MediaTek’s segmentation strategy. Smartphones powered by the MediaTek Dimensity 7450 and MediaTek Dimensity 7450X are expected to launch in the coming months.
