By language you usually mean a portable language, not machine 
language. Machine language benchmark the hardware, not the 
compiler.

But even then, domain experts are more likely to write higher 
performance code than non-domain experts, so machine language 
isn't sufficient. Therefore a large library-oriented benchmarking 
suite will favour the older language with more high performance 
libraries. Like Fortran and C/C++.

How do you benchmark cost/benefit?
