Actually, I don't quite get it. What is the major difference between two threads executing simultaneously when the OS schedules them on one core and two threads executing simultaneously as two hyperthreads on the same core? Only the scheduling delay, which gives each thread some time to fill in caches and use them before another thread kicks in to ruin everything?
