Notes: Zhaoxin publishes graphics drivers for Windows 10 (64-bit), Ubuntu 20.04 and Chinese Linux distributions such as UOS and Kylin, and also offers a Windows 11 graphics driver. However, Zhaoxin processors do not appear on Microsoft's Windows 11 supported-processor lists, which cover only AMD, Intel and Qualcomm, so Windows 11 is not officially supported by Microsoft. macOS is not supported.
