Or Windows is hiding the CPU time spent in the OS itself (kernel or whatever)
Windows 7 does not appear to do so at least. The results are very application-dependent, however. Moving around a Firefox or Chrome window will use between 5 and 9 percent of CPU time on this quad-core i7 machine with a dedicated AMD GPU. If I use certain Adobe apps, the number goes up as high as 20 percent (so 80% on a single i7 core). If I merely move around a Windows Explorer window, the percentage hovers at between 5 and 6 percent (which, again, is about 20+ percent on a single i7 core that is substantially faster than a G4 as found in a Mac Mini).
