On the evening of May 22, Xiaomi is expected to launch its self-developed 3nm mobile system-on-chip (SoC), the XRing O1, in a move that underscores both the company’s technological maturity and China’s broader drive toward semiconductor independence amid tightening US export restrictions. The chip has already entered mass production and is set to power Xiaomi’s upcoming mobile device lineup, according to chairman and founder Lei Jun.
