Xiaomi Unveils Xring O3 Processor Produced via TSMC 3nm Technology

Xiaomi has announced the Xring O3, a new mobile processor developed using TSMC 3nm process technology. The company intends to integrate this chip into an upcoming flagship foldable smartphone, with initial production shipments projected to reach between 200,000 and 300,000 units.

This development represents a continuation of Xiaomi's efforts to design custom silicon, a process that began with the Surge S1 in 2017. Following a period of inactivity, the company returned to the market in May 2025 with the Xring O1, which was the first 3nm smartphone processor designed by a Chinese company. The O1 achieved over 1 million total shipments across tablets, smartphones, and smartwatches.

The O3 processor is supported by a team of over 2,500 engineers. By utilizing TSMC's 3nm process, Xiaomi aims to improve supply chain resilience and decrease its dependence on Qualcomm and MediaTek. The company's decision to utilize 3nm technology rather than 2nm suggests a focus on yield and execution.

While the initial production volume for the O3 is limited, the company's previous experience with the O1 indicates a potential for scaling across various device categories. The long-term impact on competitors like Qualcomm and MediaTek remains to be seen, as Xiaomi's current strategy prioritizes the premium foldable segment.
