Xiaomi’s Xring O3 Chip: A 3-nm In-House Processor for Its Flagship Foldable

Xiaomi Corp. has introduced the Xring O3, its latest in-house system-on-chip (SoC) for the upcoming Xiaomi 18 Fold (and Pad 9 Pro Max). Two sources say the chip will be fabricated by TSMC on its 3-nm N3P process, with an initial run of 200,000-300,000 units. Xiaomi and TSMC have not confirmed the arrangement.

Xiaomi began its custom-silicon programme with the Xring O1 in May 2025, which has powered over a million devices. The move follows a trend among premium handset makers—Apple, Samsung and Huawei—to develop proprietary processors and reduce reliance on Qualcomm and MediaTek.

The O3 places Xiaomi among the few manufacturers shipping custom silicon for premium devices. Using TSMC’s 3-nm node gives Xiaomi access to advanced manufacturing while sidestepping U.S. export restrictions that affect Huawei. The limited volume serves as a proving ground; success could lead to broader use of Xiaomi’s in-house chips, including the upcoming Xring O100 AI processor and Xring D100 automotive chip slated for 2027.

The Next Web (TNW)

Xiaomi’s Xring O3 is a calculated gamble: leveraging 3-nm technology to showcase in-house design while limiting exposure through a modest production run. Real-world performance and its impact on Xiaomi’s silicon strategy will become clearer as the foldable reaches consumers and independent testing validates the benchmark claims.
