The Lenovo Kaitian series is a line of commercial computers developed by Lenovo for the Chinese market. The series now has a new member called the Kaitian X5d G1d.
It’s a notebook that isn’t trying to compete with mainstream ultrabooks in design or features. Instead, it is built around domestic hardware, down to the processor, and focuses on compatibility with government and enterprise systems.
Lenovo Kaitian X5d G1d Specifications
On the inside, it runs on a Loongson 3B6000M processor based on the LoongArch instruction set. This is an 8-core chip clocked at 2.4GHz, paired with a second-generation LG200 GPU core.
Lenovo says the graphics performance is more than 60 percent higher compared to the previous Loongson 3A6000. The system also offers AI acceleration exceeding 7 TOPS (INT8).
Beyond the processor, the Kaitian X5d G1d’s software is another talking point. It comes pre-installed with domestic operating systems like Kylin and UnionTech, and supports commonly used apps such as WPS Office and WeChat. More importantly, it is compatible with OFD document formats and electronic signature tools, which are widely used in government workflows.

The Loongson chip also includes a built-in security processor and supports China’s SM2, SM3, and SM4 cryptographic algorithms. Lenovo also says the system enables full-process hardware encryption for storage and documents.
On top of that, the laptop has undergone source code-level auditing, and Lenovo claims there are no hidden backdoors and that it can handle vulnerability fixes independently.
For multimedia, the laptop supports H.264 and H.265 encoding and decoding, along with HDMI and eDP display output—just enough for high-definition video playback and basic design work.
In terms of hardware, the laptop ships with 16GB of RAM and a 512GB SSD, with support for upgrades up to 32GB and 1TB. It also includes a 70Wh battery and a range of ports, including USB 3.1, HDMI, and Gigabit Ethernet.
With all of this, the Kaitian X5d G1d is relatively light at around 1.5kg and comes with a full-size keyboard.
