So I realise I'm probably a dumbass, but I'm not sure in exactly which way yet. I bought an AMD Ryzen 5 7600X CPU in mid 2020, but looking online I see the cards under that name weren't released until 2022, and the specs look different??

I wrote down all the specs for my pc after I built it so I wouldn't forget. Could it be that I just wrote it down wrong and was telling people I had a CPU that wasn't even built yet?

edit: yes I'm a dumbass it was 3600X. I'm gonna go crawl in a hole now, thanks for your time.
