Where an IBM-based score was not available we turned to a Cyrix or Intel score. At the time of writing, AMD and Centaur had not updated their sites with Winstone 98 benchmarks. This was relatively easy as the general performance characteristics of these processors are well known. After we had compiled these results but before we finished writing them up, AMD posted their own Winstone 98 test results. We have retained our original figures as AMD's results were very much as expected.
Detailed configurations are available at the manufacturers web sites .
But in general we are confident that the final scores closely reflect the relative performance of the different processors tested to within a couple of percent. From the point of view of making a purchasing decision, the very small error range is an insignificant factor. Older Test Methods January 1998 and earlier speed ratings are based on Business Winstone 97 for Windows 95. Although many of these sources have a vested interest in one CPU or another, the variation between reported Winstone scores is remarkably small - typically less than five percent. Where these benchmark variations exist, we used a middle-ranking score.
