During its 15th-anniversary strategic new product launch event, Xiaomi unveiled its groundbreaking 3nm SoC chip, the Xuanjie O1, which has already been integrated into the Xiaomi 15S Pro and Xiaomi Pad 7 Ultra. While there are still areas where it must catch up to Apple in terms of performance, the Xuanjie O1 has achieved remarkable advancements in energy efficiency and architectural optimization, signifying a significant leap forward for China's chip industry. Xiaomi invested 13.5 billion yuan in this research and development endeavor, assembling a team of over 2,500 specialists. These self-developed chips not only bolster supply chain security but also foster a synergy between software and hardware, driving down unit costs through economies of scale. Xiaomi and Huawei's complementary approaches to chip development are jointly propelling the advancement of China's chip industry. Lei Jun emphasized that chip research and development is a protracted marathon.
