Business Winstone 2001
Business Winstone tests performance in general office applications, like word processors, spreadsheets, and web browsers. This test is also usually a good indicator of overall system performance, especially where "light use" patterns are concerned (in other words, not gaming, heavy computation, or multimedia).

For general business use, the AMD processors are easily fastest. The Athlon XP 1900+ only builds on this lead.

Content Creation Winstone 2001
Content Creation Winstone is arguably more important than Business Winstone, since it tests more performance-sensitive apps, like image and audio processing suites, desktop publishing, web layout programs, and the like. As with Business Winstone, the test runs scripts using code from real applications, not just generic simulations.

The Athlon XP opens up a formidable ten-point gap between itself and the 2GHz Pentium 4. It's just no contest here.
