Nowadays, a lot of emulated tasks can access the processor directly with little or no translation, giving us the exceptional performance of emulators like VMWare and Parallels produces. 

Virtual PC was an emulator, trying to run an OS on a different type of processor. VMWare and Parallels are virtualisation programs with no emulation involved.

They do drastically different things under the hood, which is why the performance is so different.
