That is very general statement. On some particular code, some particular arch, with some particular flags Clang performs better than GCC, on other it is the other way around, on some it is wash. How it performs on larger amounts of code can be seen from standard benchmarks like SPEC, the Phoronix benchmark suite is known not to be a very good benchmark for various reasons, but that doesn't mean it isn't worth looking at it.
