Xiaomi Joins Apple, Samsung and Huawei in the Custom Chip Club, Xring O3 Is the Latest Move

Xiaomi Xring O3 is here, and its arrival, just one year after the Xring O1 launched as Xiaomi’s first-ever proprietary smartphone processor, signals that the world’s third-largest smartphone maker is moving faster on chip development than the industry expected.

The Chinese smartphone giant unveiled the Xring O3 on Monday, confirming the launch of its second in-house system-on-chip. According to people familiar with the matter, TSMC, the world’s most advanced semiconductor manufacturer, will produce the new chip using its 3-nanometre process technology. That puts Xiaomi’s second custom chip on the same manufacturing node as some of Apple’s most advanced processors, a significant technical statement from a company that only entered the custom chip space twelve months ago.

What Xiaomi Is Building and Why It Matters

A smartphone processor or system-on-chip (SoC) integrates computing, graphics, AI processing, and imaging functions into a single component. It is the most strategically important piece of hardware inside any modern smartphone, determining performance, efficiency, camera capability, and AI features simultaneously.

For years, Xiaomi has depended on Qualcomm and MediaTek for its processors, the same two suppliers that power the vast majority of Android smartphones globally. That dependency creates a fundamental constraint: Xiaomi’s product differentiation, performance ceiling, and supply chain reliability are all ultimately determined by decisions made by companies it does not control.

The Xring programme is Xiaomi’s answer to that constraint. By developing its own processors, Xiaomi gains the ability to optimise its chips specifically for its own devices, integrate proprietary features that Qualcomm or MediaTek would not build for a single customer, and insulate itself from the kind of supply chain disruptions and geopolitical risks that have become increasingly unpredictable in the global semiconductor industry.

The strategy mirrors exactly what Apple, Samsung, and Huawei have done, and the competitive advantages those companies have derived from custom silicon are now well documented. Apple’s chip leadership is widely credited as the primary reason the iPhone maintains a performance and efficiency advantage over Android competitors. Samsung’s Exynos programme, despite its struggles, gives it manufacturing flexibility. Huawei’s Kirin chips, before US sanctions disrupted supply, gave it independence from the Qualcomm ecosystem entirely. Xiaomi wants the same strategic position, and the Xring O3 is the second step toward it.

Where the Xring O3 Is Headed

According to sources familiar with Xiaomi’s plans, the Xring O3 is expected to power Xiaomi’s upcoming flagship foldable phone, with a shipment target of between 200,000 and 300,000 units.

That shipment target is modest by Xiaomi’s overall scale; the company ships tens of millions of smartphones annually, but it reflects the typical trajectory of a proprietary chip programme in its early stages. Custom chips debut in limited flagship volumes, allowing the manufacturer to validate performance and yield before scaling production more broadly.

The choice of a flagship foldable as the Xring O3’s debut vehicle is strategically deliberate. Foldable phones occupy the premium tier of the market, the segment where chip performance is most visible, most valued, and most directly compared against Apple and Samsung. Putting Xiaomi’s own 3nm chip into its most premium product category sends a clear message about the seriousness of its chip ambitions.

The Xring O1’s Track Record So Far

The Xring O3 arrives against the backdrop of the Xring O1’s commercial performance, which provides useful context for how Xiaomi’s custom chip programme is developing.

Xiaomi reported during an earnings call last week that cumulative shipments of devices powered by the Xring O1, across smartphones, tablets, and smartwatches, had surpassed 1 million units since the chip’s May 2025 launch. According to sources, approximately 150,000 smartphones based on the Xring O1 have been sold since launch.

Those are not blockbuster numbers relative to Xiaomi’s total shipment volume, but they represent a credible first-generation deployment for a proprietary chip that had never been built before. The programme has demonstrated that Xiaomi can design a chip, have it manufactured, integrate it into commercial products, and bring those products to market, the foundational capabilities that more ambitious future generations require.

TSMC Partnership, What 3nm Means

The confirmation that TSMC will manufacture the Xring O3 on its 3-nanometre process is technically significant on multiple levels.

TSMC’s 3nm node is among the most advanced semiconductor manufacturing processes currently in commercial production, the same technology family used in Apple’s A17 Pro and A18 chips, which power the iPhone 15 Pro and iPhone 16 series. Manufacturing at 3nm delivers meaningful improvements in transistor density, performance, and power efficiency compared to older nodes.

For Xiaomi, the TSMC partnership validates its chip programme in a way that matters commercially. TSMC does not take on manufacturing relationships casually; its capacity is in high demand from Apple, Qualcomm, AMD, NVIDIA, and others. Xiaomi securing 3nm production capacity from TSMC signals that the Xring programme is being treated as a serious long-term customer relationship rather than a one-off experiment.

It also positions the Xring O3 on a competitive manufacturing footing with the chips it will be compared against in the premium smartphone market.

The Broader Industry Shift: Custom Silicon as Competitive Necessity

Xiaomi’s chip push reflects a structural shift in how premium smartphone competition is evolving.

The era of differentiation through camera marketing and design is giving way to an era where the underlying silicon increasingly determines what a phone can and cannot do, particularly in AI processing, computational photography, and on-device intelligence. Companies that control their own chips control their own AI roadmap. Companies that depend on Qualcomm or MediaTek are limited to what those suppliers build for the broader market.

Apple demonstrated this most clearly. The performance and efficiency gap between iPhone and Android flagships that persisted for years was not primarily a software advantage; it was a chip advantage, built through years of sustained investment in custom silicon that Android OEMs relying on third-party chips could not match.

Xiaomi, with the resources of a company that shipped over 240 million devices in 2024 and is generating significant revenue in the premium segment, has both the motivation and the financial capacity to pursue the same strategy. The Xring O3 is the clearest evidence yet that the pursuit is serious.
