Celeron is, put bluntly, an attempt to eliminate the price
advantage that has allowed Socket 7 CPUs (AMD, Cyrix, IDT) to
continue to compete in the marketplace, by delivering low-cost Slot 1
("Pentium II") systems. [I have, in the past, compared this to GM,
having decided to build only Cadillacs, introducing a 4-cylinder
engine that only fits a Cadillac chassis, in order to compete with
BMW and Toyota....]
The first generation of Celerons achieved low cost by
eliminating L2 cache, yielding a chip that clocks faster than a
regular PII, but actually performs a bit worse. [Apparently, many
266 MHz Celerons can be overclocked reliably to about 400 MHz or so,
which may more than offset the no-caching penalty.]
The second generation of Celerons is just being released, with
128KB of L2 cache. Recall that a PII has 512KB of L2 -- but the
Celeron with L2 packs two advantages:
1. Its L2 runs at CPU speed; PII runs it at half speed.
2. Its L2 is integrated on the same single chip as the CPU -- PII's
is on a second chip inside the CPU "package". This offers a cost
saving on assembly of the CPU package -- as well as better
reliability and reduced power consumption.
Note that while you can use a Celeron in any Slot 1 motherboard,
Intel is encouraging system builders to pair it with a new 440EX
chipset (440BX, minus some features that Intel considers "high end")
to build inexpensive systems with high integration and minimal
upgrade/expansion options.
I believe some of the early Celeron models were expected to drop
below $100 this month, so you'll be seeing them in $899 PCs....
