AMD Ryzen required for Cubase 10.5 (all versions)?

Hi, all. I’m pretty sure I’m not the only user out there with a lesser AMD chip than Ryzen. I just installed 10.5 Pro, so I don’t have much experience with it yet, but I haven’t really had much issue with 10.0 Pro or prior versions. Did something change between 10.0 and 10.5 to require this jump? Are there non-Ryzen AMD users out there having issues with 10.5 that they didn’t with prior versions?

P.S. I realize every machine/configuration is different, I’m just reaching out for things I may have to look out for.
