Possible Flagship MediaTek Chip for Galaxy S25 Announced
Samsung might be making a shift in its smartphone strategy. It was recently reported that some versions of the Galaxy S25 might feature MediaTek’s upcoming flagship chip instead of Samsung’s own Exynos processor. Today, MediaTek unveiled its latest and greatest chip: the Dimensity 9400, which will be used in a range of high-end Android phones.
Samsung Galaxy S25 MediaTek Unveils Dimensity 9400: The First 3nm Chip for Android Devices
MediaTek has outpaced Qualcomm by launching the first 3nm chip designed for Android devices. This next-generation chip, the Dimensity 9400, is set to rival Qualcomm’s Snapdragon 8 Elite and Apple’s A18 Pro. It’s built using TSMC’s advanced 3nm (N3E) technology.
According to MediaTek, this new chip delivers a 35% increase in single-core CPU performance, 28% boost in multi-core performance, and 41% improvement in GPU capabilities.

The Dimensity 9400 features an octa-core CPU architecture, with one Cortex-X925 core running at 3.63GHz, three Cortex-X4 cores at 3.3GHz, and four Cortex-A720 cores clocked at 2.4GHz. Its Arm Immortalis-G925 GPU, operating at 1,612MHz, offers 40% faster ray-tracing graphics and 44% better power efficiency.
The GPU supports WQHD+ resolution with refresh rates up to 180Hz and is compatible with advanced visual technologies like Dolby Vision, HDR10, and HDR10+. Plus, it supports devices with tri-fold screens for enhanced flexibility.
Paired with the latest 10.7 Gbps LPDDR5X RAM—the fastest available for Android—the chip boasts significant memory upgrades, including 3.5MB L2 cache (double the previous amount), a 50% increase in L3 cache to 12MB, and an additional 10MB of system-level cache.
Its integrated NPU 890 is 35% more power-efficient than the previous model, providing advanced AI functions such as generative fill for ultra-clear photos even at 100x zoom. The NPU also enhances power management for 4K video recording at 60fps.
The Dimensity 9400’s modem supports mmWave and sub-6GHz 5G bands, along with backward compatibility for 2G, 3G, and 4G networks. It also offers the latest in connectivity features like Wi-Fi 7, Bluetooth 5.4, NFC, and a USB Type-C port.
Location and navigation support is robust, including compatibility with standards like BeiDou, Galileo, GLONASS, GPS, NavIC, and QZSS, ensuring accurate positioning across the globe.
Samsung Galaxy S25 Might Feature the Dimensity 9400 in Some Regions
MediaTek confirmed that its new chip is already being shipped to smartphone manufacturers. Devices like the Oppo Find X8 and Vivo X200 are expected to launch with the Dimensity 9400 chip next month.
Some reports suggest that Samsung may choose to use the Dimensity 9400 instead of its in-house Exynos 2500 for some Galaxy S25 and Galaxy S25+ models, depending on the market. This could mean a shift in Samsung’s strategy as it looks to optimize performance and efficiency for its flagship line.
