Huawei unveils homegrown desktop PC with its own chip and HarmonyOS

The domestic desktop claim

Huawei has introduced its first desktop PCs built around its own processor and operating system. The Qinyun HM650 and HM650g models are based on the Kirin X90 chip, which the company first debuted in 2025. According to Huawei, everything from the processor to memory, storage and power supply is manufactured in China.

What the Kirin X90 offers

The Kirin X90 packs 10 Huawei-designed Armv8-based Taishan cores in a 4+4+2 layout. All cores support simultaneous multithreading (SMT), allowing up to 20 threads. The chip also includes a Maleoon GPU and a dedicated neural processing unit for AI workloads.

The manufacturing reality

Huawei does not officially disclose the Kirin X90's process node. A teardown by TechInsights found the chip is made by SMIC using its 7nm-class N+2 technology — behind the leading-edge nodes from Intel, TSMC and Samsung.

How "fully domestic" holds up

While the components are fabricated in China, the production chain still relies on equipment from the Netherlands, the US and Japan, materials from Japan, intellectual property from the UK, and EDA software from the US and partly China. The supply chain is therefore not fully independent.

The OS side

The machines run HarmonyOS Enterprise Edition, which uses Huawei's own kernel. This reduces dependence on Windows, but compatibility with Windows-based enterprise software could remain a limitation.
