This year (2025), the competition in the flagship smartphone SoC market has intensified with the introduction of a new flagship SoC to challenge the big guns. This is the Xring O1 vs Dimensity 9400+.
Xiaomi has officially announced its in-house Xring O1 SoC to rival established players like MediaTek’s Dimensity 9400+. Both chipsets are built on advanced 3nm processes and aim to deliver top-tier performance. In this SoC comparison, we’ll look into the specifications and capabilities of these two SoCs to determine how Xiaomi’s newcomer stacks up against MediaTek’s seasoned offering.
Xring O1 – Xiaomi’s Flagship SoC
The Xring O1 is Xiaomi’s first self-developed flagship mobile chipset, announced in May 2025. Fabricated using TSMC’s second-generation 3nm process, it features a 10-core CPU setup, a 16-core Immortalis-G925 GPU, LPDDR5T RAM, UFS 4.1 storage, and a MediaTek T800 modem. It is set to debut in devices like the Xiaomi 15S Pro and Xiaomi Pad 7 Ultra.
Dimensity 9400+ – MediaTek’s Flagship SoC
The Dimensity 9400+ is MediaTek’s flagship SoC for 2025, built on TSMC’s first-generation 3nm process. It boasts an octa-core CPU, a 12-core Immortalis-G925 GPU, LPDDR5X RAM, UFS 4.1 storage, a MediaTek’s Imagiq 1090 ISP and APU 890 NPU. The chipset offers 5G connectivity (Sub-6GHz and mmWave), Bluetooth 6.0, and WiFi 7. It is found in high-end devices like the Vivo X100 Pro+ and Oppo Find X7 Ultra.

CPU Performance
The Xring O1 features a 10-core CPU with higher clock speeds on its prime cores which potentially offers better single-threaded performance. The Dimensity 9400+ has an 8-core setup with a mix of high-performance and efficiency cores. While both chips are powerful, the Xring O1’s extra CPU cores may provide an edge in multitasking and demanding applications.
GPU Performance
With a 16-core Immortalis-G925 GPU, the Xring O1 offers more graphics cores compared to the 12-core version in the Dimensity 9400+. This could translate to better graphics performance, especially in gaming and high-resolution video playback. Clear win to the Xring O1.
Benchmark Scores
Benchmark results show the Dimensity 9400+ leading in AnTuTu scores, which should indicate a strong overall performance. However, the Xring O1 has higher GeekBench scores. This suggests that the Xring enjoys superior CPU performance in both single-core and multi-core tests.
RAM and Storage Support
The Xring O1 supports LPDDR5T RAM, which offers better bandwidth and lower latency compared to LPDDR5X used in the Dimensity 9400+. Both chipsets support UFS 4.1 storage, ensuring fast data read/write speeds.
Display Capabilities
The Dimensity 9400+ supports higher display resolutions up to 3840 x 2160p, making it suitable for devices with ultra-high-definition screens. The Xring O1 supports up to WQHD, which is still more than sufficient for most flagship smartphones.
Camera and Video
The Dimensity 9400+ supports camera resolutions up to 320MP and video recording at 8K @60fps, offering more advanced imaging capabilities. The Xring O1 supports up to 200MP and 8K @30fps video recording, which is still impressive but slightly behind its competitor.
Connectivity
Both chipsets offer comprehensive connectivity options, including 5G (Sub-6GHz and mmWave), WiFi 7, and Bluetooth. However, the Dimensity 9400+ features Bluetooth 6.0, providing improved range and data transfer rates over the Xring O1’s Bluetooth 5.4.
Conclusion
Xiaomi’s Xring O1 marks a significant milestone as the company’s first self-developed flagship SoC, showcasing impressive CPU and GPU setups. While it excels in certain areas like CPU performance and graphics capabilities, the Dimensity 9400+ leads (slightly) in overall benchmark scores, display support, and camera features. Both chipsets are formidable contenders in the flagship SoC arena, and the choice between them may ultimately depend on specific device requirements and what (you) the end user prefers.
