What are the fundamental differences between the new hetzner cloud servers and the old VPS?

Question

Hetzner

Hetzner launched a line of "cloud servers", on the surface there are such differences at the maximum rate (new CX51 vs old CX60):
+
lower price
-
less traffic and disk space included , fewer
operating systems to choose from.
Memory, "number of processors" - the same.
Does it make sense to switch if there is more than enough traffic and space for me?
Will I lose something in performance?

Answer 1

In the new line, the processors are newer, theoretically it will be faster. Don't know about stability yet. I ordered a CX21 a couple of days ago. While it works fine.
Judging by the results of Geekbench4, the new line is noticeably faster:
CX20
CX21

Answer 2

I don’t know about others, but my outgoing channel was cut, it was ~ 200 mb / s, it became 20-40 at the peak ....
