Running Windows on a Mac

Tidbits reports: [edited]

Our friends over at MacTech have taken on the laborious task of running benchmarks on the popular virtualization programs Parallels Desktop and VMware Fusion, comparing them against each other, running both Windows XP and Windows Vista, against Apple's Boot Camp, and against a standard PC laptop.

Windows XP outperforms Windows Vista by 17 to 30 percent in virtualization, so if you want the fastest Windows performance, stick with Windows XP.

When running Windows XP, Parallels Desktop was somewhat faster than VMware Fusion, and even a bit faster than Boot Camp.

If you want to run Windows Vista, VMware Fusion provides noticeably better performance than Parallels Desktop on all tasks involving raw processing, whereas Parallels Desktop offers significantly better integration with Mac OS X (and thus real-world performance) for all cross-platform tasks.

Keep in mind that these conclusions are relevant only for the things MacTech tested, which did not include gaming (where Boot Camp probably has the edge over both virtualization options) or applications that can use multiple processors (where VMware Fusion would probably outperform Parallels Desktop).
