Xiaobei Chen (陈小北) has been competing for a year. His best event is the 3×3: a personal-best single of 7.10, set at Xi'an Open 2026, puts him in the top 1.5% of the 288,433 people who have ever been ranked in the event, and 527th in China. Until July 2008, no official 3×3 solve in the world had been that fast. Across 3 competitions since November 2025, he has put 82 official solves on the record across seven events. Solve to solve, his 3×3 times vary about 16% around a typical one, an early reading from 8 counted rounds. His 3×3 best has come down from 9.07 in November 2025 to 7.10, a 22% improvement. Xiaobei has entered three competitions, more competitions than 69% of everyone who has ever competed.

Reading this page: a single is one solve's time · an average is the middle three of five solves, best and worst discarded · a PB is a personal best · a DNF (did not finish) is an attempt with no valid result: a popped piece, an unsolved face, an over-limit memorisation · top X% compares against everyone ever ranked in that event, which is fairer than raw rank because event pools differ tenfold.
