Xiaomi Mi 18 Ultra Mystic Ring Edition Leaked: World’s First Mystic Ring O3
Fast Technology reported that Xiaomi launched its annual flagship, the Xiaomi 15S Pro, last May. This phone is a derivative of the Xiaomi 15 Pro and was the first to feature the Xuanjie O1 chip. This is Xiaomi’s most powerful self-developed mobile phone chip, marking Xiaomi as the first company in mainland China and the fourth globally to independently develop and design 3nm mobile phone chips.
The birth of the Xuanjie O1 not only proved Xiaomi’s R&D strength in the field of cutting-edge chips, but also filled the gap in the field of high-performance 3nm mobile processors for domestic companies. A year later, news about Xiaomi’s next-generation self-developed chip has once again attracted attention, and the even more powerful Xuanjie O3 is already on its way.
According to a blogger, Xiaomi is secretly developing an Ultra model powered by the O3 chip, which may be the future Xiaomi 18 Ultra. This chip was designed from the outset to deliver extreme performance, aiming to further solidify Xiaomi’s leading position in the high-end flagship market.
Leaks indicate that the Xuanjie O3 still employs an advanced 10-core architecture design, codenamed lhasa. This chip is manufactured using TSMC’s 3nm process, and its CPU comprises two Cortex-X925 super cores, two ultra-high-frequency Cortex-A725 large cores, four high-frequency Cortex-A725 large cores, and two Cortex-A520 small cores.

This extremely complex core combination means that the performance of the Xuanjie O3 will reach new heights. It’s worth noting that the application of this chip will no longer be limited to smartphones. In the future, it will be widely used in various smart terminal devices under Xiaomi, achieving full ecosystem coverage of self-developed chips.
This cross-category application strategy will further expand the ecosystem application scenarios of its self-developed chips. Through deep collaboration of underlying hardware, Xiaomi can more effectively enhance the all-scenario interconnected smart experience, creating a smoother and more intelligent digital life loop for users.
With the arrival of the Xuanjie O3, Xiaomi’s continued breakthroughs in the semiconductor industry chain are evident. This not only significantly enhances Xiaomi’s core competitiveness but will also strongly promote the overall development of the domestic semiconductor supply chain, demonstrating the determination of domestic brands to cultivate core technologies.
