Intel Pentium II OverDrive

 Windows NT Performance

A similar picture can be found under Windows NT, where the Pentium II OverDrive extended the life of AnandTech's Pentium Pro system by raising the bar of competition the system had to offer. However, as mentioned before, the limited improvements in the FPU of the Pentium II OverDrive over the original Pentium Pro keep the High End Winstone 99 improvements to a minimum.
