Talk Around Town: Xiaomi Claims Its XRing O3 Chip Beats Apple and the Whole Mobile Market — On Paper

What the Rumor Mill — and Xiaomi Itself — Is Hollering

Well, butter my biscuit and call it a benchmark: Xiaomi stood up on August 24, 2026, and announced the XRing O3, which the company describes as a 10-core all-big-core mobile SoC built on TSMC's N3P 3nm process node. According to Xiaomi's own announcement, the die measures 133mm² and packs 24 billion transistors. The chip has entered mass production, per Reuters sources cited by AndroidHeadlines, and Xiaomi says it will debut inside the Xiaomi 18 Fold and Xiaomi Pad 9 Pro Max, both slated for a China launch in September 2026.

The loudest crow coming off Xiaomi's porch is about benchmark scores. The company claims the XRing O3 notched a Geekbench 6.5 single-core score of 3,945 and a multi-core score of 15,221 — figures Xiaomi says are 31% and 61% higher than the XRing O1, respectively. Even more boldly, Xiaomi claims that 15,221 multi-core result outperforms the Apple M4, according to Notebookcheck and HotHardware's coverage of the announcement. And on AnTuTu V11, Xiaomi claims a score of 5,228,014, which the company says makes the XRing O3 the first mobile SoC to crack five million points on that benchmark, per TechBriefly and TechTimes.

What We Actually Know for Certain, Hoss

Now, some of this here chip has solid roots in the ground. Multiple specialist outlets — Notebookcheck, HotHardware, and AndroidHeadlines — corroborate the architectural details, and the TSMC manufacturing relationship carries extra weight because Reuters independently cited it. The CPU cluster layout is confirmed across sources: two Arm C1-Ultra cores running up to 4.35GHz, four C1-Premium cores up to 3.68GHz, and four C1-Pro cores up to 3.15GHz, with no efficiency cores at all — a pure all-big-core arrangement.

Also confirmed by multiple outlets is that the XRing O3 is described as the first mobile SoC to support LPDDR6 memory. TechTimes and VGTimes both report that the 96-bit bus delivers up to 113.8 GB/s of bandwidth, which Xiaomi says represents a 48% improvement over the LPDDR5X setup in the XRing O1. Xiaomi also announced two companion chips alongside the O3: the Xring O100, billed as a 6nm AI accelerator for smartphones, vehicles, and robotics, and the Xring D100, which the company describes as China's first 3nm AI processor for autonomous driving, according to TechBriefly.

Researcher Daniel Lemire, writing on X, characterized the XRing O3 as roughly matching Apple cores in single-threaded performance and being considerably faster in multithreaded execution — though Lemire himself noted that a forthcoming Apple processor announcement could shrink that gap in a hurry.

What Nobody Has Proven Yet, Not by a Country Mile

Here's where the pickup truck runs out of road: every single performance number on the table right now comes from Xiaomi's own controlled launch event. Not one independent lab has gotten its hands on a retail XRing O3 device, because, as AndroidHeadlines notes, the shipping phones aren't even on sale yet. Beebom and AndroidHeadlines both say flat out they're holding their conclusions until retail units can be tested.

TechGrapple specifically flags that Xiaomi's AnTuTu score of 5,228,014 was obtained in a cooled laboratory environment — meaning real-world scores under actual heat and sustained load are expected to come in lower. The comparison to Apple M4 multi-core performance is Xiaomi's own marketing assertion, not an independent measurement. Similarly, Xiaomi's claim that the XRing O3's memory latency bests Apple's A19 Pro has zero independent corroboration at publication time, per the source packet.

There's also a precedent worth chewing on like tough jerky: when the XRing O1 launched, Notebookcheck's independent testing found it came in about 18% slower than the Apple A18 Pro in single-core performance, despite Xiaomi's enthusiastic pre-launch positioning. That history gives plenty of reason to squint hard at the O3's Apple-parity claim until somebody outside Xiaomi's lab can confirm it.

The Trade-Offs Worth Side-Eyeing

Going all-big-core is like putting nothing but big V8 engines in every vehicle on your farm — powerful as all get-out, but they guzzle fuel and run hot. Xiaomi frames the all-big-core design as a power-efficiency improvement, but TechTimes, Beebom, and TechGrapple all flag that ditching efficiency cores entirely raises legitimate questions about power draw and thermal throttling under sustained real-world use. That trade-off simply cannot be evaluated until retail hardware ships and gets tested under normal conditions.

On the manufacturing side, AndroidHeadlines points out that the XRing O3 lands on TSMC's 3nm N3P node at the same moment Qualcomm and MediaTek are preparing to launch 2nm chips. That means Xiaomi's chip could be a full manufacturing generation behind its sharpest rivals by the time those competing products ship — a gap that matters even if the current benchmark claims eventually prove accurate on retail hardware.

Our Analysis: Impressive Barn-Raising, But Nobody's Moved In Yet

This is analysis, not reporting: Xiaomi has built itself a very tall flagpole and run a very bright flag up it. The structural facts — TSMC N3P fabrication, the all-big-core CPU layout, LPDDR6 memory support — are credible and meaningfully differentiate the XRing O3 on paper. A 10-core design with no efficiency cores and the first mobile LPDDR6 implementation is genuinely interesting silicon, whatever the benchmarks eventually say.

But the performance claims are, right now, pure company gospel. Xiaomi's own prior chip launched with claims that didn't survive independent scrutiny, and the benchmark environment — laboratory cooling, controlled conditions — is about as close to real-world phone use as a county fair pig race is to the Kentucky Derby. Until a reviewer picks up a Xiaomi 18 Fold off a store shelf, runs Geekbench in a warm room, and publishes the results, the gap between what Xiaomi says and what the chip actually does remains wide open. The smart money keeps its wallet in its pocket until September.
