Intel processors support multiple operating systems to ensure their compatibility and flexibility in different application scenarios. This topic describes the versions of the operating system images that are compatible with eighth-generation Intel instance types.
Background information
Eighth-generation Intel instance types use fourth-generation Intel® Xeon® Scalable (Sapphire Rapids) processors, and are built based on the x86 architecture. The following instance families are eighth-generation Intel instance families:
g8i, general-purpose instance family
c8i, compute-optimized instance family
r8i, memory-optimized instance family
For more information, see Overview of instance families.
Operating system versions that support Sapphire Rapids processors
The following table describes the operating system versions that support Intel® Xeon® Scalable (Sapphire Rapids) processors.

Suggestions on how to use Intel instance types
When you purchase eighth-generation Intel instance types, we recommend that you use the operating system versions supported by eighth-generation Intel instance types, as described in the preceding table. If you want to use an operating system version that is not described in the preceding table, we recommend that you perform one of the following operations:
Select an instance type that supports the operating system version that you want to use.
Use a community image that contains the operating system version that you want to use. For more information, see Create an ECS instance by using a community image.
Specific features of the processors that are used by Intel instance types are not supported by earlier operating system versions. If you use operating system versions that are not described in the preceding table together with eighth-generation Intel instance types, proceed at your own risk. You can determine the operating system version that you need based on your applications.

When you select a public image on the buy page for Intel instance types, the latest version of the image is provided by default. If you want to purchase an earlier version of a public image, call the RunInstances operation with an image ID specified.
Operating system features, performance optimizations, basic software package updates, and security updates vary based on the operating system version. For more information, see Release notes for public images and Release notes for Alibaba Cloud Linux images.
