How fast is the Power Mac G5 series compared to Windows PCs?
According to Apple-published SPEC CPU2000 benchmarks, and independently tested by Veritest, the Power Macintosh G5 destroys comparable Windows PCs. In “SPEC rate” tests, the Power Macintosh G5/2.0 DP (PCI-X) was 95% faster than a Windows PC with a single 3.0 GHz Intel Pentium 4 processor and 42% faster than the Windows PC with dual 3.06 GHz Intel Xeon processors. Some claimed that Apple’s benchmark testing was rigged, but the Power Macintosh G5 systems trounced the comparative Windows PCs in a series of real world application tests as well. In an Adobe Photoshop “45-filter function test” the original Power Mac G5 models — the Power Macintosh G5/1.6 (PCI), G5/1.8 (PCI-X), and G5/2.0 DP (PCI-X) — were 1.5 times, 1.7 times, and 2.2 times faster, respectively, than a Windows PC with a single 3.0 GHz Intel Pentium 4 processor. In similar testing, the dual-processor Power Macintosh G5/1.8 DP (PCI-X) was 76% faster than a Dell Dimension XPS with a single 3.2 GHz Pentium 4 processor. Accordi
