Not really, code in low-level GPU shader language (I believe that's no longer allowed though) and compare it to HLSL. Compare intrinsics speed with inline assembly. Sadly, we live in a world where the lie that compilers can optimize better than humans is widely spread. The reality is, compilers can optmize better than your everyday-javaguy (the kind of person who believes you can just throw more processing power at a problem while the programmer just needs to abstract ad nauseam). I like using frameworks, libraries, high-level languages as much as anyone in here, but I know ASM will always be faster, just not always suitable for the issue.
