MediaTek has officially refreshed its mid-range SoC lineup with the introduction of the Dimensity 7450 and the specialized Dimensity 7450X. While these new chips introduce native dual-screen support tailored for the next generation of clamshell foldable smartphones, Xiaomi has strategically decided not to integrate this silicon into its upcoming device portfolio.
Architectural Upgrades and Dual-Screen Native Support
Both the standard Dimensity 7450 and the foldable-centric 7450X are built on TSMC’s highly efficient 4nm manufacturing process. The defining difference between the two is that the 7450X natively supports dual-screen display functionality, making it purpose-built for clamshell-style flip phones that utilize both an inner folding panel and an outer cover screen.
Compared to the previous-generation Dimensity 7300, the 7450 series brings two substantial performance boosts:
-
CPU Overclocking: The eight-core CPU retains the familiar architecture but pushes the four Arm Cortex-A78 performance cores to a maximum clock speed of 2.6GHz (up from 2.5GHz). The four Cortex-A55 efficiency cores remain clocked at 2.0GHz.
-
GPU Enhancements: The integrated Arm Mali-G615 MC2 GPU has received an impressive 24% frequency increase, significantly enhancing graphics rendering and gaming stability.
Additionally, the chips are equipped with a sixth-generation NPU that yields a 7% improvement in AI engine performance, optimizing edge AI tasks and AI-driven camera computational photography. They feature the Imagiq 950 ISP (supporting up to 200MP sensors and 4K recording), and support modern connectivity standards including 5G Release 17 (3.27 Gbps peak downlink), Wi-Fi 6E, and Bluetooth 5.4.
Why Xiaomi is Steering Clear
Despite the appeal of a cost-effective, foldable-ready processor, Xiaomi is officially sitting this one out. The reasoning is deeply rooted in current market dynamics and Xiaomi’s regional strategy: The global market for foldable devices is currently experiencing softer demand than initially projected. Launching a mid-range flip phone for the global market requires massive R&D and marketing investments that currently do not align with the projected sales returns.
Historically, Xiaomi’s most innovative foldable devices (like the MIX Fold series and MIX Flip 2) have remained exclusive to the domestic Chinese market. Since their foldable strategy is currently hyper-focused on delivering ultra-premium, flagship experiences to a localized audience, a mid-range global chip like the Dimensity 7450X simply does not fit their current product roadmap.
