Xiaomi's XRing O3 Posts 3,945 Single-Core and 15,221 Multi-Core on Geekbench With Ten High-Performance Cores and No Little Cores
Announced 2026-08-24 on TSMC 3nm with LPDDR6, the chip drops the conventional big.LITTLE arrangement for an all-high-core ten-core design and breaks 4GHz. Daniel Lemire's analysis, the 906-point Hacker News submission, highlights a 44MB cache and a core with 21 execution ports built for data-parallel work, matching Apple on single-thread while pulling well ahead on multi-thread. It is the strongest evidence yet that Chinese custom silicon has closed the single-thread gap rather than only the core-count gap.
