Xiaomi's new Xring O3 CPU matches Apple in single-core and leads in multi-core.

Xiaomi's Xring O3 processor, detailed by Daniel Lemire on X, uses TSMC 3nm and C1-Ultra cores with massive 44 MB total cache. It scores 3,945 single-core and 15,221 multi-core on Geekbench, beating Apple in multithreaded tasks. The chip features 21 execution ports, six supporting SIMD (128-bit), plus SME2 and SVE2 for AI and data parallelism. Lemire notes this reveals a trend toward wider cores with more execution units, SIMD, and larger cache, though Apple may soon counter with its next processor.

What commenters are saying

Commenters split: some praise the architectural achievement, others question Geekbench's cross-platform validity and sustained performance. Skeptics note benchmarks were done in a cold room and may not reflect real phone use. A correction highlights that the CPU uses ARM-designed cores from a UK company, made in Taiwan, not fully Chinese. Two camps emerge: those focusing on technical specs (cache, ports, memory bandwidth) versus those arguing political and national security implications, with the latter dominated by top-ranked comments warning against Chinese hardware risks.
