Xiaomi unveiled its in-house flagship chip, the Xring O3, on Monday. Built on a 3-nanometer process and manufactured by TSMC, it puts pressure on long-time suppliers of core components Qualcomm and MediaTek. However, reports indicate the initial production target is only 200,000 to 300,000 units, indicating very limited output.

The flagship phone’s heart is now powered by a domestically developed Chinese chip. On Monday, Xiaomi officially launched its self-developed processor, Xring O3, directly challenging Qualcomm and MediaTek, which have been manufacturing its core components for over a decade. In an official Weibo announcement, Xiaomi emphasized that the Xring O3 delivers more power-efficient image processing and enhanced on-device AI computing capabilities, marking a significant step forward in Xiaomi’s expansion of its self-developed chip strategy since the Xring O1 in 2025.
At the same event, chips such as the Xring O100 and D100 were also unveiled. A SoC (system-on-a-chip), in simple terms, is a design that integrates the processor, graphics chip, and AI processing units onto a single silicon wafer—it is the most expensive component in a smartphone and the key determinant of user experience limits. For over a decade, this critical piece has been almost entirely controlled by Qualcomm and MediaTek; Xiaomi developing its own SoC is equivalent to touching the most sensitive nerve in the supply chain.
3-nanometer process, targeting Apple and leaving Huawei behind
Xiaomi founder Lei Jun via a WeChat post revealed that the Xring O3 is built using a 3-nanometer process, a node that approaches the technology used in Apple’s latest A19 Pro chip and surpasses the self-developed chips of China’s largest competitor, Huawei.
According to Reuters, the chip is manufactured by TSMC, marking a key detail as this is the first time Xiaomi’s in-house chip has been entrusted to TSMC. In terms of specifications, the Xring O3 chip has an area of 133 square millimeters and contains over 24 billion transistors, making it the world’s first mobile processor compatible with LPDDR6 memory, offering a memory bandwidth of 113.8 GB per second—a 48% improvement over its predecessor, the Xring O1. The CPU features a 10-core design, including two C1-Ultra cores with a maximum clock speed of 4.35 GHz, four C1-Premium cores at 3.68 GHz, and four C1-Pro cores at 3.15 GHz; the GPU is a 16-core G2-Ultra NX, bringing its overall specifications close to flagship levels.
Self-assessment score: Multi-core performance increased by 60%
Xiaomi's official self-test results show impressive figures: multi-core performance has improved by approximately 60% compared to the previous generation, GPU graphics performance has increased by up to 85%, energy efficiency has improved by 64%, AnTuTu benchmark score reached 5,228,014, and Geekbench multi-core score stands at 15,221.
However, these are all self-reported metrics from Xiaomi, not independently measured by third-party benchmarking agencies; the actual user experience and battery performance can only be verified after the device is officially released. The first device to feature the Xring O3 is the foldable smartphone, the Xiaomi 18 Fold, expected to launch in September 2026.
Production capacity is only 200,000 units—can Xiaomi really decouple?
However, Bloomberg Industry Research analysts Steven Tseng and Rebecca Wang note that Xring O3 remains on the 3-nanometer node, while Qualcomm and MediaTek’s next-generation flagship chips are already preparing to transition to 2 nanometers, indicating that Xiaomi is focusing its resources on architecture and feature upgrades rather than process shrinkage.
The redesigned processing unit, faster memory, and enhanced on-device AI capabilities indeed help differentiate Xiaomi's flagship devices from competitors; if the Xring series can be extended to more devices, it will also improve Xiaomi's overall R&D efficiency, allowing the design investment to be amortized across more product lines.
But Bloomberg also noted that the reported shipment target for this chip is only 200,000 to 300,000 units, a very limited volume compared to the tens of millions of units annually shipped by Qualcomm and MediaTek—making it a drop in the ocean. This means Xiaomi will remain heavily reliant on Qualcomm and MediaTek as its primary suppliers in the short term, with its in-house chip serving more as a bargaining chip than a comprehensive replacement.
Mobile sales are sluggish—can chips save Xiaomi?
Xiaomi was once the top smartphone manufacturer in China by market share, but now both its smartphone and electric vehicle businesses are facing challenges due to weak domestic demand in China. According to Counterpoint Research, Xiaomi experienced the steepest shipment decline among major hardware manufacturers in the second quarter of this year.
Investors are also concerned that Xiaomi’s aggressive pricing strategy for its latest SUV could further squeeze the company’s profit margins. Against this backdrop, the Xring O3 is less a technological breakthrough and more a strategic move by Xiaomi to reclaim narrative control at a time when revenue pressure is at its peak.
Chip autonomy is ultimately a battle for bargaining power, not an overnight supply chain revolution. Shipping 200,000 chips won’t achieve true decoupling, but it’s enough to give Xiaomi an additional card to play when negotiating prices with Qualcomm and MediaTek in the next round.
