A Mac is a comprised of a heck of a lot more than just a PPC Processor. They must be using some sort of proprietary Apple ROM technology to allow it to run the Mac OS. I'm interested to see if Apple will try to sue them. (Mind you with Quartz Extreme, a lot of it is offloaded to the video card) the site didn't mention anything about offloading the graphics to the PC's video card. All of these things take processing power, and the Mac has a LOT more of them than Windows has.

Transparencies, shadows, smooth animations, magnifications, live updating of data changes across multiple applications. their UI is positively simple compared to OS X's. Good for earlier Mac games that were in color. The latest version (Parallels Desktop 17) provides a simple way to run any ARM Linux.

They don't list any benchmarks on the site, but they do mention that it is about 500 times slower by Raw CPU cycle speed.
