Supported Processsors List - HCL

I have such processor:

Intel® Core™ i5-4300U CPU @ 1.90GHz × 4

I run on RHEL 8.7 ... upgrade to 9.0 is not possible because processor is not supported.

So my question is:
- where can I find list of supported processors?

I asked because I have a plan for this year to upgrade my test machine to sth with AMD AM5 Ryzen 7/9 7XXX Series. I do not want to buy sth that is by default not supported by RedHat / OpenShift
