Xiaomi Xring O3 Chip First Light-Up Achieved, TSMC N3P Process Mass Production Imminent

Xiaomi's in-house Xring O3 chip has achieved first light on TSMC's N3P process and entered full-device integration testing; a successful launch in a flagship foldable by September 2026 would mark the jump from million-unit proof-of-concept to high-end competition.

01

First light — how far along is this chip?

Xring O3 returned from the foundry in late 2025 and lit up on first power-on. It is now in full-device integration testing.
This means → the chip's core logic works. The next gate is fitting it into a real phone and validating thermals, signal, and battery life at system level.
In plain terms = "first light" is like a new engine firing for the first time — promising, but a long way from a car you can drive. Full-device integration is the real mass-production hurdle.
02

N3P plus a tri-cluster design — what is different about the specs?

Supply-chain sources say the chip is built on TSMC's N3P — the third iteration of TSMC's 3 nm node, offering further power and performance gains over N3E.
Leaked specs show a tri-cluster CPU: one ultra-large core (>4 GHz), one "Titan" core, and several efficiency cores (>3 GHz) — a departure from the conventional big-plus-little two-cluster layout.
This means → the extra middle tier could balance performance and power draw more flexibly. But none of these specs have been officially confirmed by Xiaomi.
03

How did the first generation sell — is the production track record real?

Xiaomi president Lu Weibing disclosed that the first-gen Xring O1 shipped in three devices, totaling over 1 million units.
This reflects a completed end-to-end chain — design → tape-out → mass production → device integration — no longer a lab exercise.
In plain terms = a million-unit track record proves the supply chain can deliver. The real test for O3 is whether that capability can move up to the flagship price tier.
04

What will be the first product — and when can you buy it?

Market expectations point to the Xiaomi MIX Fold 5 as the O3 launch vehicle, with a window around early September 2026. A tablet may follow.
Xiaomi is not abandoning Qualcomm: regulatory filings show the Xiaomi 18 Pro series is expected to carry Qualcomm's 2 nm flagship processor.
This means → Xiaomi is running a dual track — in-house silicon for foldables to test the high end, Qualcomm for the slab flagship as a safety net.
05

Is the chip only for phones — how far does Xiaomi's platform ambition reach?

Lei Jun has publicly stated that in-house chips may extend to Xiaomi's auto business. Lu Weibing also revealed a 1.7-meter full-size humanoid robot set for factory-line deployment.
Industry expectations see Xring eventually fitting smart cockpits, domain controllers, and embodied AI — the field of giving AI a physical body that can perceive and act in the real world.
In plain terms = Xiaomi's endgame is not a single phone chip but a shared platform across phones, cars, and robots. But the leap from a phone SoC — a system-on-chip that packs processor, modem, and GPU onto one piece of silicon — to a cross-device platform is enormous, and whether it can be made is the central test of the entire strategy.
