The tests here warrant attention because complex Adobe PhotoShop 5.0, Adobe Premiere 5.1, Macromedia Director 7.0, Macromedia Dreamweaver 2.0, Netscape Navigator 4.6 and Sonic Foundry Sound Forge scripts are run. Content Creation Winstone 2000 keeps multiple applications open at once and switches among those applications. All of these have 'hot spots', as ZD likes to call them that truly test the system, but the CPU especially. Think of this benchmark as the "Crusher" ZD-equivalent test, which pushes real world programs to their limits (as opposed to Quake II timedemo1) on a system level.
The Athlon 1.2GHz wallops the competition in this test, though its ATA/100 hard drive likely helped it beat the competition.
