PS2 has several dedicated cores, so I guess PCSX2 is exploiting the cores of a PC to make the emulator running faster. There is a small difference, though. CPU frequencies between PS2 and PS3 have a huge gap and PS3 can be considered as real 7/8 cores (it is not clear whether the 7th SPU can be used by a game) whereas AMD FX and i7 (4-core) only offers real 4 physical cores (8 logical processors which not fully runnable in parallel).
