In May 2025, Xiaomi took the stage in Beijing to unveil its self-developed chip, the Xuanjie O1. This cutting-edge chip is crafted using TSMC's second-generation 3nm process and features an innovative ten-core quad-cluster architecture. By achieving this milestone, Xiaomi not only emerged as the first company in mainland China but also the fourth globally to launch a flagship mobile phone chip based on the 3nm process. Moreover, it boasts a CPU super core that can reach a clock speed of up to an impressive 3.9GHz. Looking ahead, it's anticipated that the Xuanjie O2 will make its grand entrance in the second to third quarters of 2026. There's a higher probability that it will be released in September, possibly finding its place in Xiaomi's vehicles. Lei Jun, a key figure at Xiaomi, mentioned that developing self-developed chips is a lengthy process, typically taking three to four years. He also revealed that Xiaomi's next strategic move will be to develop a four-in-one domain control system. This move is aimed at paving the way for seamless integration of chips into vehicles. By extending the reach of the Xuanjie chip to the automotive sector, Xiaomi aims to bolster its capabilities in full-scenario computing networks. Additionally, this expansion will help Xiaomi reduce its dependence on external suppliers, ensuring greater control and flexibility over its technological advancements.
