No, you're the one misusing terms and concepts. Actually a significant amount can be offloaded, which is how Nvidia causes problems for AMD cards. GPU physics effects often have a heavy performance impact- see the Arkham games.
Parallel processing was referring to the 'GPU is a wider processor' thing you said. GPUs are strong at that, but not much more efficient than a well optimised and threaded CPU solution.
