	tl;dr: Xiaomi's new Xring O3 chip matches Apple's single-threaded performance and beats it on multithreaded workloads, featuring 44MB of cache (more than most laptop CPUs) and unusually wide C1-Ultra cores with 21 execution ports, six of which handle 128-bit SIMD. The design reflects a broader trend toward massively parallel cores with more execution units, expanded SIMD, and larger caches—that's where the transistor budget is going.
	HN Discussion: ↓Article omits critical power efficiency and thermal metrics needed for fair comparison ↓Comparison is misleading since it's older Apple chip and more cores vs fewer ↓The chip is really ARM's design, not Xiaomi's innovation, undermining the achievement framing ↑This signals broader Chinese competitive rise in silicon and manufacturing ~Lab benchmarks don't reflect real-world phone thermal-constrained performance
