:AMD instance type and operating system compatibility

Last Updated:Oct 10, 2025

Different AMD instances may require specific driver and kernel versions to run. When you purchase an AMD instance type, you should use an officially supported operating system version. This ensures that the operating system includes the necessary driver and kernel versions for your AMD instance. This topic describes the compatibility between different generations of AMD instances and various operating system images.

Operating system support for different generations of instance types

Different generations of AMD instances are compatible with specific operating system versions. The AMD Zen architecture was released in 2017. Some new processor features may have functional limitations on older operating systems. The following table lists the compatibility between different generations of AMD instances and various operating systems. It also provides links to official compatibility documents.

When you purchase an AMD instance type, use one of the officially supported operating system versions listed in the table.

If you must use a different operating system version for specific needs, select a different supported instance type. Alternatively, you can search for and use your target operating system from community images. For more information, see Create an instance from a community image.
Important

If you run an unsupported operating system version on your AMD instance type, you must assess and assume the potential risks.
