Is Go faster than CPP?

No. Go cannot replace C everywhere because it’s a higher-level language . It has a garbage collector and runtime that you can’t get rid of. This makes Go, unlike C, unsuitable for certain low-level use cases like embedded systems with limited memory and hard real-time programming.

golang ended up being more of a Python replacement. Go was never intended to replace C++ . It was aimed at a very specific target: engineers, especially junior engineers, writing function-as-a-service software.

Usually C++ code will run somewhat faster than Go code . C++ compilers are generally better, and in some ways the C++ language permits writing more efficient, if sometimes less safe, code. In my experience the difference ranges from Go being a few percent slower to Go being twice as slow.7 Eki 2014

Go is a procedural and concurrent programming language. C++ is an object-oriented programming language . Go does not contain classes with constructors and deconstructors. C++ does contain classes with constructors and deconstructors.13 Eki 2020
