At least in Quake, both Celeron 400s are able to go toe-to-toe with the Pentium II 400. In fact, no score deviated more than two frames per second between the three machines. Please keep in mind that while both Celerons are running at 6.0 x 66.6Mhz, the Pentium II is running off of the faster 100Mhz setting, and the Celerons have the extra benefit from an L2 cache that runs at twice the speed of the Pentium II's. Although the Socket-370 PPGA Celeron showed a slight advantage over the SEPP package, do consider that the average difference in frames per second is under 0.5 -- so for all intents and purposes, they're equal.
