AMD CPU Naming Confusion Ryzen 5 7 9 v 3000 4000 5000 7000

I'm currently still using an Intel i7 6700k set up that I built back in June 2016 and I'm doing some research with the view of potentially upgrading around Black Friday.

Looking into the currently available options and I'm really confused by the AMD CPU naming conventions.

I see on the OCUK website that there are sections for :
AMD Ryzen 7000 Processors (10)
AMD Ryzen 5000 Processors (11)
AMD Ryzen 4000 Processors (2)
AMD Ryzen 3000 Processors (1)
AMD Ryzen 9 Processors (5)
AMD Ryzen 7 Processors (7)
AMD Ryzen 5 Processors (7)

On the face of it I thought that didn't seem too complex but then when I actually look at model numbers I'm left a bit stumped.

Looking at comparison tables there are Ryzen 5 7 9 all with 7xxxx CPUs and so on.
I'm baffled how a Ryzen 5 7xxx fits in against say a Ryzen 7 5xxx etc. Some are Zen 3 and some are Zen 4, the latter I believe being the newer ones.
Though I've seen benchmarks where a Ryzen 9 5950X Zen 3 benches better than a Ryzen 7 7700X Zen 4.

I'd presume the 9 beats the 7 beats the 5 and a 7xxx would beat a 5xxx etc, though that doesn't seem to be the case all the time.

I tried searching in various places but I didn't find anything that explained the hierarchy in an idiots guide.

I think I've worked it out that the 7000 are newer than 5000 etc and the 5 7 9 are like the intel i3 i5 i7 i9 within each of those?

Could someone kindly confirm if I've got that right? If not please do correct me please!

Thanks!

Thanks for the replies, that's a lot clearer now.

No wonder you're confused, OCUK's filters and sections are shockingly bad. If they anyone doing UI design they need a P45

Indeed, I remembered when they were relaunching the website and said there would be an improvement in this area.

Can't even filter motherboards by ATX ITX etc.

I also wanted to be able to filter monitors by their Vesa DisplayHDR rating too, which you can't do.

Making it hard for customers to find what they want does not seem ideal for a retail website.

Go to mechanical keyboards and there is a filter for TKL mini (60%) but only one is tagged but there is more than one on the page. Go to the 60% keyboard category and there is a filter for mechanical but again only one is tagged.

I'm sure there are many more examples.
