Xiaomi is set to launch its self-developed 3nm smartphone chip, Xuanjie 01 (Xring 01), at a product event on May 22. This positions Xiaomi as the fourth global brand to introduce a 3nm processor, following Apple, MediaTek, and Qualcomm, potentially challenging Huawei's Kirin chips, which are limited to 7nm due to US trade restrictions. The company plans to invest 50 billion yuan ($6.9 billion) over the next decade in high-end chip development, signaling a significant shift in the competitive landscape of smartphone technology.
