If the C API only provides Python-level semantics, then it will roughly have the speed of pure Python (modulo bytecode execution). There are important use cases for the C API where it is desired to have fast type-specific access to Python objects such as tuples, ints, strings, etc. This is relied upon by modules such as _json and _pickle, and third-party extensions as well.
