Do some languages have more mature compilers and therefore produce better binaries?

C has existed for a long time and is still in use in high performance situations.

Go is fairly new.

If I write a substantial program in both languages (using only the intersection of features), will the C program have more advanced compiler optimisations and therefore run faster?

Potentially, but not necessarily. Some features of the language give it implicitly more speed. For example, Golang has garbage collection which is inherently slower than manual memory handling like what is done in C.

Sometimes this is a double-edged sword, as Go  makes it easier to do complicated things at scale consistently, whereas having a minor memory issue in C is more likely and it could slow down the application.
