In certain cases, sure - inlining potential is far greater in C++ than in C.

For idiomatic C++ code that doesn't do any special inlining, probably not.

IOW, you can rework fairly readable C++ code to be much faster by making an unreadable mess of it. You can do that for any language (C included).

But what we are usually talking about when comparing runtime performance in production code is the idiomatic code, because that's how we wrote it. We didn't write our code to resemble the programs from the language benchmark game.
