In this case, I think this is poorly written. Andrew was talking about the Zig compiler and the data-oriented approach he used, leading to better compile speed.

About the speed of the generated code, I have not seen many benchmarks, but I expect to see minimal differences with C. With better semantics around pointer aliasing and parallel-friendly loops they could produce faster machine code than C, but likely not by a huge margin.
