Now Apple has started to offer Unix (the operating system in OS X), people can run industry standard benchmarks on Macs, and SPEC tests show Apple's performance claims are false, according to Mac User. The benchmarks were run by a German computer magazine, c't, which has published the results. In fact, a 1GHz Mac runs at roughly the same speed as a 1GHz Pentium III which, as c't points out, has been on the market for 18 months. (Thanks to Paul Thurrott at Wininfo for the tip.) The latest scores are here.
