By language you usually mean a portable language, not machine

I believe there are more platforms that have an assembler, but
not a C++ compiler and C++ libraries you want to use.
Machine language benchmark the hardware, not the compiler.
It only means assembler reaches the theoretical limit of
performance by choosing right language abstractions, that you
wanted to benchmark.
But even then, domain experts are more likely to write higher
performance code than non-domain experts, so machine language
isn't sufficient.
Some domain experts don't know (or don't want) any programming
language and use matlab instead.
Also what's about cost/benefit ratio?
How do you benchmark cost/benefit?
By eyeballing the source.
