Xiaomi’s Xring O3 chip turns up the heat on Qualcomm and MediaTek

Xiaomi unveiled its second-generation in-house smartphone processor, the Xring O3, on Monday, August 24, and the timing could hardly be more deliberate. The chip is expected to debut inside the Xiaomi 18 Fold, a foldable flagship that Trusted Reviews reports Xiaomi has confirmed for a September launch event — putting the new silicon at the heart of its most visible product of the season.

What we know — and what we don’t

The announcement itself is straightforward: the Xring O3 is the successor to the Xring O1, Xiaomi’s first proprietary smartphone processor, launched roughly a year ago. What makes this launch significant is the manufacturing arrangement reported around it. According to two people familiar with the matter who spoke to Reuters, TSMC is expected to build the chip on a 3-nanometre process. Neither Xiaomi nor TSMC has confirmed the foundry deal, and Xiaomi has not yet published official specifications for the O3 or a release date.

The production numbers reportedly attached to the chip are telling. Shipments are targeted at 200,000 to 300,000 units — a deliberately modest volume that signals a premium, controlled rollout rather than a mass-market transition.

Why Xiaomi is going in-house

The strategic logic is clear: by designing its own silicon, Xiaomi reduces its dependence on external suppliers such as Qualcomm and MediaTek for its most differentiated products. That matters for margin control, supply-chain resilience, and the ability to tune hardware and software together. The O3 is not meant to replace Qualcomm across Xiaomi’s entire portfolio; instead, it is a flagship statement piece, and the 200,000–300,000 unit target suggests Xiaomi is using the foldable segment as a controlled proving ground.

The specs on paper

Trusted Reviews reports that the Xring O3 posted a score of 5,228,014 in the AnTuTu V11 benchmark, the highest any smartphone processor has recorded so far. The chip is built around a deca-core CPU with two C1-Ultra cores clocked up to 4.35GHz, four C1-Premium cores up to 3.68GHz, and four C1-Pro cores up to 3.15GHz. In Geekbench 6.5, it scored 3,945 single-core and 15,221 multi-core. Apple’s A19 Pro remains ahead in single-core, but the Xring O3 pulls far ahead in multi-core.

Xiaomi’s own testing also shows the chip outperforming the Xring O1 by 85, 94, and 182 percent across three GPU benchmarks, and beating the Apple A19 Pro in all three of those tests. The Xring O3 also supports LPDDR6 memory with bandwidth reaching 113.8GB/s, a feature that should help a large-screen foldable handle heavy multitasking. A separate report from The News adds that the chip packs over 24 billion transistors into a 133 mm² die, uses an all-big-core design with no efficiency cores, includes a quad-core NPU delivering up to 200 TOPS, and claims to be the world’s first mobile SoC with native LPDDR6 support.

It is worth noting that none of these specifications have been confirmed by Xiaomi itself. Still, the pattern is consistent: a flagship-tier chip aimed squarely at the performance crown.

What it means for business buyers

For enterprise and B2B technology buyers, the Xring O3 is less about raw benchmark numbers and more about what it signals for the broader mobile supply chain. Xiaomi is joining Apple, Google, and Samsung in the ranks of smartphone makers that control at least part of their silicon. That shift has real consequences for procurement: if Xiaomi’s flagship devices increasingly use in-house chips, Qualcomm and MediaTek lose a prominent launch partner, and the bargaining power of those suppliers erodes over time.

There is also a practical angle for businesses that deploy Xiaomi devices in the field. In-house silicon typically allows tighter integration between hardware and software, which can translate into better power efficiency, more consistent thermal performance, and longer software support cycles. For fleet managers and IT decision-makers, these are meaningful operational factors when evaluating foldable devices for productivity use.

The small shipment target, however, should temper expectations. A 200,000–300,000 unit run is not a volume play; it is a validation exercise. Xiaomi will use the 18 Fold to learn how its chip performs in real-world conditions, gather field data, and refine the next generation before committing to larger-scale production. The financial stakes are also substantial, since a 3nm design from TSMC is expensive to develop and manufacture at low volume.

Risks to watch

Several open questions remain. The TSMC manufacturing link is still unconfirmed, and shipping targets come from unnamed sources. Xiaomi has not named the foldable officially, though Trusted Reviews says the Xiaomi 18 Fold brand has been confirmed and a September event is planned.

There is also the question of yield and cost. The Xring O3 is reportedly built on TSMC’s advanced 3nm node, which offers performance and efficiency gains but commands premium pricing. At a production volume of only a few hundred thousand units, Xiaomi will need to price the 18 Fold carefully to avoid absorbing losses on each device. And because the foldable form factor itself is still maturing, any hardware or software bugs in the first Xring O3 generation could dent Xiaomi’s credibility in premium silicon.

The bigger competitive risk is timing. Apple’s A19 Pro is ahead in single-core performance, and Qualcomm and MediaTek are not standing still. Xiaomi’s in-house program is promising, but it is still one generation old. A single misstep in the foldable launch could slow the momentum Xiaomi has built with the O1 and O3.

The takeaway

Xiaomi’s Xring O3 is a high-stakes move that pairs an ambitious in-house chip with a low-volume, high-visibility foldable launch. For B2B readers, the story is not just about one processor; it is about the accelerating shift toward vertically integrated silicon among major Android vendors. If the 18 Fold ships in September as reported and delivers on its performance claims, Xiaomi will have demonstrated that it can compete at the very top of the mobile silicon market. If it stumbles, the 200,000-unit target ensures the damage stays contained. Either way, the industry will be watching the benchmark results closely.
