How would I know if my P3 700mhz CPU is KATMAI?

KATMAI = 256k or 512k L2 cache

 

[Tanked]

Katmai's are 512K cache.

Thanks for clearing that up, Tanked.

I'm pretty sure that the Katmai core only scaled up to around 600 MHz. The Coppermine core took over from there. Basically, the Katmai core was the Deschutes core + SSE instructions using the same old .25 micron process and 512k of half-speed cache; Katmai was the original Pentium III core. Coppermine moved everything to a .18 micron process and came with 256k full speed cache. Many consider that the Pentium III brand should have been introduced with the Coppermine core.

In any case, I'm 95% sure that your 700 MHz processor is Coppermine. 🙂

AFAIK, all 700s are Coppermines.

The only desktop PIII 700MHz ever released was the Coppermine core/100MHz FSB.
Katmai never exceeded 600MHz, and that in relatively low volume.

Katmai never exceeded 600MHz, and that in relatively low volume.

Intel planned a 650mhz version but never released it

as has been said, no Katmai scaled above 600 mHz, so it's pretty easy to tell whether your 700 mHz CPU is a Katmai or not 🙂

Yep, Katmai never went over 600 mainly because it barely could. I had a factory unlocked katmai @ 550 that could run at like 625. So the 700 is a coppermine and should overclock pretty well, most 700s did 133 fsb (933mhz) with relative ease, mine did 1050 with some volt boosts.

Yup, Katmai only went up to 600Mhz/100Mhz. The 550Mhz chips are pretty scarce, and 600Mhz scarcer still. Terrible overclockers, if you care. But because these were the highest speed chips that worked on some older motherboards (original 440bx with early VRMs for example), they are still in some demand.

As everyone says, its a Coppermine, because Katmai never went over 600. If you wanted to do it with software, something like CPUID or CPUZ would tell you that.
