For a program though there is no distinction as they are all seen as "virtual cores".
@flying - they used to be d9+openGL, they left open gl to do dx10 (which seems to be absent).

Actually multi-thread and multi-core are different.
CPUs can have more or elss unlimited threads (till memory/resources run out) - a thread is a small unit of processing block that the OS can schedule.
All threads within the mutli-threaded program must share the same core - unless they are multi-process (utilizing multiple cores).
