We still regress, according to LNT 8% on zen2:
https://lnt.opensuse.org/db_default/v4/SPEC/graph?plot.0=335.437.0=309.437.0=346.437.0=276.437.0=398.437.0=417.437.0=295.437.0;
and 12% on zen3:

I have only seen this when compiling with -march=native on Zen, but even at -O2
(which I overlooked yesterday, and which is also confirmed by LNT).
