All objects with P54C chip
A refresh of the P5 operating at 75MHz, 90MHz or 100MHz using 3.3 volt. It is made using a 0.6 µm manufacturing process. The P54C has a 1.5x multiplier in order to let the chip run faster than the motherboard. Motherboards weren't able to run faster, but the chips could easily go above 66MHz.
The die-shrink made it cheaper for Intel to produce the chip and the lower voltage made the Processor run a lot cooler.
