A 486dx4/120 runs at 40MHz externally.
"Pentium systems" can run at a variety of external clock rates. The following
information comes from "The Pentium Family-A Technical Overview", Intel order
number 242423-002.
133MHz Pentium has a 66MHz external speed
120MHz Pentium has a 60MHz external speed
100MHz Pentium has either 50MHz or 66MHz external speed
90MHz Pentium has a 60MHz external speed
75MHz Pentium has a 50MHz external speed
> (NOTE: this is one of the major differences between the processors).
If the external frequency is one of the major differences distinguishing a
Pentium from a '486, why can you get a 486dx50 and a Pentium 100 or 75, both
running at the same external frequency of 50MHz?
