The Mac uses the PowerPC chip from Motorola/IBM -- a totally different chip from the Intel or AMD used with Windows. However, there are software products sold that let you run Windows in a window within the Macintosh OS. The Intel chip's instruction set is emulated, so it runs slower than on a fast PC -- which would invalidate the test you mentioned. [You can remove a hard drive from a Macintosh and use it in a Windows system. You can (re-)format it for FAT32 or NTFS or whatever. Older Macs used only SCSI drives. In recent years they use ATA drives just like PCs. But I don't think this is what you were asking about.] There are standard chunks of C source code that can be compiled and run on each platform that purport to test that platform's raw performace. You run into issues of compiler optimizations, etc. There are also standard suites of application tasks, such as opening certain large files, scrolling through a long Word document, using certain Photoshop filters, etc., that are performed on both Macs and PCs. They usually show that a G3 or G4 Mac performs like a Pentium 3 or Athlon at about double the megahertz, with some large exceptions in both directions. (I've seen Photoshop operations that are 30x as fast on the Mac as on the PC.) Hope this helps! Cheers, -Roy.
