The celerons have a 128K integrated cache running at clock speed. The
celerons tag ram covers the entire 4G address space. The pentium II's
have a 512K integrated cache running at 1/2 clock speed and the tag ram
covers 512M only. The celerons run a {standard} bus clock of 66 Mhz
and the p2 run a {standard} bus clock of 100Mhz. The celerons are
incredibly overclockable. The 300, 333, and 366's are regularly
overclocked to a 100Mhz bus speed (450, 500, and 550Mhz respectively)
with great success.
At the standard bus speeds, a P2 will outperform a celeron at the same
CPU frequency. If you overclock a celeron to a 100Mhz bus clock, it will
generally equal to outperform a P2 running at the same CPU speed (ie., if
you overclock a 333mhz celeron to 450 (100mhz bus clock), except for a
few very specific apps, it will equal or outperform a 450Mhz P2).
The celerons and the P2s share a common floating point unit. Either will
outperform a K6/K7 in floating point operations.
The P3 adds new instructions, but until the coppermines, retains the P2
cache. The new P3 coppermines add a better cache, faster instruction
execution, and a 133 Mhz bus clock.
