Imagine a modern computer, where let's say Python is a high level programming language and needs to be interpreted in order to execute a piece of code. You could write some code in C, compile it, which will be much closer to the actual hardware and therefore runs faster.
Now, if we take a C64, if I write a piece of code in BASIC, would it be much slower than Assembly? If so, is there any comparison I could make? Is it even possible to quantify it this way?
