How many CPU / GPU cycles are wasted unnecessarily?


For years I have been asking this question to myself: how much code actually wastes CPU / GPU cycles, assuming optimization flags are set to their highest option possible?

Is there actually such thing with the flags set on, or not?

I'm really curious.

How do you define wasted cpu cycles ? The compiler wrongly emitting redundant code ? The programmer doing something particularly silly ? Python running code that would be 10x as efficeint if rewritten in C ?
