You mean the implementation is faster than the one in C. Because nothing is “faster than C”.

If you don't count manual SIMD intrinsics or inline assembly as C, then Rust and FORTRAN can be faster than C. This is mainly thanks to having pointer aliasing guarantees that C doesn't have. They can get autovectorization optimizations where C's semantics get in the way.
