That's what my question actually was about.
https://en.wikipedia.org/wiki/SSE3#CPUs_with_SSE3
I see ssse3 on all my x86_64ers, I see sse3 on my 32bit atoms, but I
don't know if ssse3 implies sse3 and I don't know what -msse3 actually
does to the instruction set when being used on x86_64ers and which
impact it has
https://en.wikipedia.org/wiki/SSE3#New_instructions
(-msse3 is not part of Fedora's gcc implicit CFLAGS).
and that is really sad because it wastes for 99.9% of users performance
and hence i override the builds of perormance relevant software since
years with optimized falgs while hat -fstack-protector-all in use long
before Fedora supported and switched to -fstack-protector-strong
in other words: you get the small performance impact of hardening back
by better utilize your existing hardware instead castrate your whole
software to nostalgic decades

So, Fedora or Linux as a resort to escape Windows on old HW is not a
Fedora target anymore?
come on and install a recent Fedora on such old machines, guess what
SSE3 or not is your smallest problem
