+!!! warning "Please Check CPU Compatibility"
+
+    With Rocky Linux 9.0, some older CPUs will not work well, or perhaps at all. The following architectures are considered minimum requirements for a successful install:
+
+    * AMD and Intel 64-bit architectures (x86-64-v2)
+    * The 64-bit ARM architecture (ARMv8.0-A)
+    * IBM Power Systems, Little Endian (POWER9)
+    * 64-bit IBM Z (z14)
+
+    For more information on supported architectures and the risks of using those that are unsupported, see the upstream release note on the subject [here](https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/9/html/9.0_release_notes/architectures).

 Some highlights from this release are detailed next.
