Thanks but... bear with me https://www.tomshardware.fr/articles/comparatif-cpu-amd-inte... what are those ryzen 3/5/7 TR ?

13xx, 15xx, 17xx, ThreadRipper.

For gen 2, that'd be:

23xx, 25xx, 27xx, ThreadRipper.

I think they picked the names/numbers to show some kind of equivalence with i3/5/7, but that's not quite it.

Don't forget the 1700X and 1800X.

ThreadRipper is interesting. It requires a different socket than the other desktop processors and is targeted more at workstation class machines.

In servers there are Epyc and Epyc 2.

ThreadRipper seems more like a Xeon competitor to me. Something for the server room crowd.

Epyc is the server Xeon competitor, Threadripper is a workstation cpu.

That'd be EPYC, their server offering.

Threadripper is their workstation CPU.

That's exactly it

slow (3), medium (5), fast (7), elite (Threadripper)

If you don't want to spend more than USD$800 on the CPU alone, don't look at the elite/threadripper line.

What is your budget? That is the first question you need to answer instead of trying to understand the entire line of chips, look at how much you have to spend, and then find the fastest one within the budget.

It's useless to try to think about the entire line of CPU's when you will only buy 1 chip (unless you are representing Dell and need to buy thousands of chips)
