Xiaomi Is Building an In-House Chip Foundation Spanning Mobile Devices, Edge AI, and Automotive Applications with O3, O100, and D100

Overview

This report examines Xiaomi's newly unveiled Xring O3, O100, and D100 and analyzes its full-stack in-house chip strategy as it expands from flagship mobile computing into edge AI and intelligent driving. Deutsche Bank believes this initiative aims to establish a common computing foundation across smartphones, AI devices, robotics, and electric vehicles, while integration with HyperOS strengthens Xiaomi's premiumization and ecosystem differentiation.

Core views

At the "Xiaomi Xring Chip Technology Communication Conference," Xiaomi unveiled a more comprehensive portfolio of in-house chips, including the flagship mobile chip Xring O3, the AI accelerator Xring O100, and the intelligent-driving chip Xring D100. Deutsche Bank believes the three chips show that Xiaomi is attempting to establish a common chip foundation for smartphones, AI devices, robotics, and electric vehicles. Deeper control over the core computing stack could enable tighter hardware-software coordination, faster product differentiation, and greater supply-chain resilience while strengthening Xiaomi's bargaining power with external suppliers such as Qualcomm, MediaTek, and Nvidia. Xiaomi also demonstrated an "AI Cube" desktop AI terminal prototype in which the three chips work together, capable of locally deploying models with 120 billion and 3 billion parameters, in line with its long-term "Human x Car x Home" ecosystem strategy. Xring O3 handles computing tasks for flagship mobile devices. It uses TSMC's second-generation N3P 3nm process and integrates 24 billion transistors in a die area of 133 square millimeters. It arrives only 15 months after the launch of Xring O1, Xiaomi's first in-house smartphone processor, which integrated 19 billion transistors. O3 has a 10-core CPU comprising two 4.35GHz C1-Ultra cores, four 3.68GHz C1-Premium cores, and four 3.15GHz C1-Pro cores, along with a 16-core G2-Ultra NX GPU and a redesigned NPU architecture. Its NPU and AI architecture deliver 200 TOPS of tensor computing power and 3.13 TFLOPS of vector performance, primarily supporting Xiaomi's on-device MiMo large language models and AI models. For imaging, the fifth-generation ISP supports a single camera of up to 432MP or a triple-camera configuration of 64MP, 64MP, and 50MP. Xiaomi also says O3 is the world's first mobile chip to support LPDDR6, offering speeds of up to 10,667Mbps and memory bandwidth of 113.8GB/s. The chip will be used in the Xiaomi 18 Fold smartphone and Xiaomi Page 9 Pro Max tablet, both scheduled for launch in September. Xring O100 targets on-device large-model inference in consumer electronics, smart homes, and robotics, using a 6nm process and a 14-core NPU. Its key design feature is 3D Wafer-on-Wafer packaging, which stacks one 6nm NPU compute wafer with two high-speed DRAM wafers and uses hybrid bonding with a 1.4-micrometer pitch and 2.58 million physical interconnects. This shortens the data path between computing and memory and alleviates the conventional "memory wall." Xiaomi says O100 can provide memory bandwidth of up to 1.22TB/s and local AI inference performance of 330 tokens per second, aiming to enable high-bandwidth MiMo models to run directly on end devices rather than relying entirely on cloud computing. Xring D100 further extends Xiaomi's in-house chip strategy into core automotive computing. Xiaomi positions it as China's first high-compute intelligent-driving AI chip manufactured using a 3nm process. The chip combines a 20-core high-performance CPU with a 16-core NPU, supports up to 160GB of unified memory, and can locally run models with up to 200 billion parameters. D100 has completed validation and is targeted for commercial deployment in 2027. Xiaomi's current electric-vehicle platform primarily uses Nvidia Thor chips and previously used Orin. Deutsche Bank believes that successful deployment of D100 could gradually reduce Xiaomi's reliance on third-party intelligent-driving processors and promote tighter integration among its chips, software, and assisted-driving technology stack. At the broader strategic level, Deutsche Bank views the combination of the Xring chip portfolio and HyperOS as a step toward deeper vertical integration for Xiaomi. The report believes this could allow Xiaomi to coordinate performance, power consumption, imaging, and on-device AI at the system level, shorten product development cycles, and create a more distinctive user experience. This direction is broadly similar to Apple's model of ecosystem differentiation through its in-house A-series chips and iOS. If successfully executed, in-house advanced-process SoCs could not only demonstrate engineering capabilities and technological leadership but also support Xiaomi's premium positioning, strengthen its technology brand, and gradually reduce its reliance on standardized externally sourced components. The report maintains its Buy view with a target price of HKD 48.00. The reference price as of August 24, 2026, was HKD 27.82, with a 52-week price range of HKD 21.42 to HKD 59.45.

Analysis framework

The report first examines the process technology, architecture, computing power, memory, and product deployment timelines of the three Xring chips to define their respective roles in flagship mobile devices, on-device AI, and intelligent driving. It then analyzes how in-house chips affect hardware-software coordination, product development, supply-chain dependence, and bargaining power with suppliers. Finally, using Apple's vertical integration model as a reference, it assesses the strategy's potential significance for Xiaomi's premiumization, technology image, and "Human x Car x Home" ecosystem.
