What's the difference between...

[DDR-PIII]

An Intel P-III @ 1.3Ghz and a Celeron @ 1.3Ghz ? or an P-III@ 1.4ghz and a P-4 @ 1.4 ghz ?

P-III @ 1.3 (133FSB) is a coppermine -256 , built on .18 micron core.

Cel-t @ 1.3 (100FSB) is a Tualatin core 256 L2 cache (same as P3) data pre fetch... basicly its a P3 on a .13 die shrink and a few extras

P-III @ 1.4 (133FSB) is a Tualatin core 512 L2 cache with all the Tualatin Features (die shrink ect)....

P4 (*edit* 100FSB x4 *edit* forgot to add the FSB) is a new core , 786 if you will, not comparible to the P3's...
But 256 L2 chace, .18 micron core.....

want more?

There is no 'stock' coppermine 1.3GHz P3; the 133FSB P3 coppermines stopped at 1GHz (IIRC, Intel did attempt a 1133/133FSB coppermine but it wasn't stable). The 1100E (100FSB) is the highest 'stock' coppermine P3. P3s >= 1133 MHz are Tualatin core CPUs.

BOTH the coppermine and the Tualatin core will do 1.3Ghz ---The Tualatin cele is generally represented with an A and the Tualatin P3 is represented with an S. Coppermine core ranges from 533-1.1Ghz stock and high overclocking range is 1.4+ with most coppermine chips topping out in the mid 1300's on air cooling

And if yer talking about performance difference then the coppermine P3 will outperform the coppermine cele at the same clock speed....But a Tualatin cele will outperform the coppermine P3....and the Tualatin P3 with 512 L2 Cache definitely outperforms the P4.

You can find numerous benchmarks all over the place but thats the basics

looks like i was wrong (tried to jump the gun a bit)...
yes the 1.13 was recalled...
