PS: My old CPU failed when installing proprietary Linux binaries, due
to not supported SS{,S}E3 instructions, my new, just an
Intel Celeron doesn't. AFAIK no distro compiles packages against higher
than SSE2. Super-CPUs such as the Ryzen e.g. provide SSE4.1, SSE4.2
instructions, but as long as packages aren't compiled using this
and similar instructions, you gain not much. Actually your electricity
bill will rise for more or less no advantage.
