The following performance test results use industry standard benchmark and application test suites. Windows® application benchmark suites demonstrate the overall system performance an end user would achieve while running the most popular applications. Ziff-Davis’ Winstone® 96 and Winstone 32 benchmark suites are based on 13 different Windows applications that represent the most current 16-bit and 32-bit software available.
