Sort of. When I think of "which language is fast", I think of "when using idiomatic style". That, to me, is a good measure of how fast the language is, in general.
Benchmarks on aggressively optimized code are fun and interesting too, because they can tell you the hard lower limits of performance in the language runtime. But most people will never end up optimizing their code so thoroughly, so it's not particularly useful if you're interested in how a real working program will perform.
