Difference in these P3 cpu's????

[FFactory0x]

I have 2 P3's yanked from systems

The p3-500 is long and im guessing slot 1???

The other is square like the t-breds and is a p3-500. What kind is this (socket/slot etc)??

Also why the difference

Socket 370. It was changed froma slot because its cheaper to produce.

Which has various breakdowns into PPGA, FCPGA, and FCPGA2. 😉

- M4H

Bad guess. It's actually slot-A. The A stands for Athlon 😉
Seriously though, isn't it possible that the slot 1 p3 will have off-die cache?

The slot 1 Pentium III's were Katmai .25 um process
The socket 370 Pentium III's were Coppermine .18 um process Flip Chip Pin Grid Array

the latter were, as above said, cheaper to produce, AND they ran cooler too AND over clocked much better too (I have the PIII 550E FC-PGA Coppermine. 🙂

Umm...there were lots of slot 1 coppermines too.

IIRC, Intel made slot1 Coppermines up to 1Ghz.

Pentium socket/slot basics

Pentium 1: Socket chip. Cache located on mobo. Cache runs @ FSB speed.

Pentium II Slot 1: Cache runs @ 1/2 CPU speed. Needed to move cache chips close to CPU. CPU and cache put on small PCB, which is the reason for the slot design.

PIII socket 370. Cache moved to on die full speed. No need for PCB slot design any longer, so back to a socket. They were also made in Slot 1 form for use in existing Slot 1 mobos.
