TL; DR
- MediaTek has launched the Dimensity 7450 and 7450X on TSMC’s 4 nm process for midrange phones and flip foldables, with the 7450X adding native dual-display support.
- Both chips use the same hardware: 4x Cortex-A78 at 2.6 GHz + 4x Cortex-A55 at 2.0 GHz, Mali-G615 MC2 GPU, LPDDR5 / LPDDR4X RAM up to 6400 Mbps, and UFS 3.1 storage.
- Hardware is unchanged from the Dimensity 7400, making this another small refresh that may create confusion for buyers trying to understand what is actually new.
MediaTek has officially announced the Dimensity 7450 and Dimensity 7450X. The regular 7450 is meant for standard smartphones, while the 7450X is aimed at flip-style foldables. The main extra feature on the 7450X is native dual-display support, allowing inner and outer screens to work seamlessly together.
Both chipsets are built on TSMC’s 4 nm process and use the exact same octa-core CPU setup: four Arm Cortex-A78 performance cores clocked at up to 2.6 GHz, along with four Cortex-A55 efficiency cores at 2.0 GHz. Graphics are handled by the Arm Mali-G615 MC2 GPU.
Memory support includes LPDDR5 and LPDDR4X up to 6400 Mbps, while storage support covers UFS 3.1 and UFS 2.2. Connectivity features include 5G Release 17 with 3CC carrier aggregation for peak downlink speeds of 3.27 Gbps, Wi-Fi 6E, and Bluetooth 5.4. Camera support goes up to 200 MP sensors through the Imagiq 950 ISP, with 4K video recording support.
The bigger issue here is that the Dimensity 7450 series is basically the same silicon as the Dimensity 7400 from February 2025. You still get the same 4x 2.6 GHz Cortex-A78 + 4x 2.0 GHz Cortex-A55 CPU clocks, the same Mali-G615 MC2 GPU, the same LPDDR5 / LPDDR4X support up to 6400 Mbps, and the same UFS 3.1 storage interface.
The only real changes are minor software gaming optimizations and some NPU tweaks for AI tasks. For most users, that is not going to translate into a meaningful difference in daily use. Launching a new name for nearly identical hardware only makes the lineup harder to understand, especially for buyers comparing phones on spec sheets.
Compared to the older Dimensity 7300, there are at least two actual upgrades. The four performance cores now run 100 MHz higher at 2.6 GHz instead of 2.5 GHz, and the Mali-G615 MC2 GPU runs at around 24% higher frequency. Outside of that, RAM speed, storage support, and the 5G modem remain the same.
The 7450 series is expected to appear first in upcoming devices like the Motorola Razr 70 lineup, with the 7450X likely powering the foldable models in the coming weeks.
