A P133, for instance, would perform as well as a Pentium 133, while a P150 would equal the performance of a Pentium 150. MDR Labs, run by Michael Slater of the independent analyst firm MicroDesign Resources, uses Winstone 96 to determine a processor's P-rating.
Users are attuned to the P number.
In our case, P is performance, not Pentium. As time goes by manufacturers will see that our naming convention is the best way to go. With an average Winstone score of 79 and an average Graphics WinMark score of 32.8, the two systems collectively outperformed PC Magazine's Pentium 166 Editor's Choice, the SAG SFF 166, whose Winstone score of 76 and Graphics WinMark score of 32.3 were previously unprecedented. Only two Pentium 166 machines, the SAG SFF 166 and Micron P166 Millennia Plus, could best the 6x86 systems' average Disk WinMark 96 score of 1195. The average Pentium 166 Disk WinMark score was a considerably lower 1110.
