Xiaomi celebrated its 15th anniversary with a strategic product launch event in Beijing on Wednesday, unveiling a suite of cutting-edge devices headlined by its most advanced in-house processor to date. The milestone event saw Founder and CEO Lei Jun reflect on the company’s journey while charting an ambitious path for its AI-driven future.
“Fifteen years of innovation would be unimaginable without the trust of our users and partners,” Lei stated during his keynote, marking a rare emotional pivot in his address. “This moment isn’t just about looking back—it’s about redefining what’s possible in smart device integration.”
Breaking the Nanometer Barrier
The star of the show was the Xuánjiè O1 chipset, featuring an industry-leading second-gen 3nm fabrication process. Engineered for the flagship Xiaomi 15S Pro, the 109mm² silicon packs over 19 billion transistors and achieves thermal management breakthroughs with its 10-core CPU cluster, including dual Cortex-X925 cores clocked at 3.9GHz for instantaneous app response.
ARM’s latest Immortalis-G925 GPU, stacked with 16 compute cores, delivers desktop-grade rendering capabilities. Early benchmark tests at AnTuTu Labs show the chipset surpassing 3 million points, positioning Xiaomi’s bespoke silicon among elite mobile processors.
The AI Arms Race Intensifies
Xiaomi’s neural processing unit (NPU) leapfrogs competitors with 44 TOPS of dedicated AI performance—outpacing Apple’s A18 Pro by 18%. The third-generation MiLM architecture reduces power consumption by 40% while enabling novel features like:
- Real-time “Reasoning Visualization” for AI-assisted writing
- Context-aware notification summarization
- Offline natural language search across system apps
The launch roster—including the 15S Pro, Pad 7 Ultra, and Civi 5 Pro—signals Xiaomi’s vertical integration strategy, leveraging proprietary chips to differentiate in saturated markets. Analysts predict the Xuánjiè O1’s architecture could eventually power IoT devices and automotive systems as the company expands its ecosystem.
