What's the difference on a P!!!450 Stepping 2 and Stepping 3

[Notti]

I have two CPU's both P!!! 450MHz but:
one is: x86 Family 6 Model 7 Stepping 2
other is: x86 Family 6 Model 7 Stepping 3

Can any1 tell me what the difference is? I went on www.intel.com and that page sux :-(
They are not showing the same performance.

Thanks

don't have the technical changes to hand but in general a new stepping corrects some problems(errata) found with the previous stepping. for example, the new stepping may o/clock better than previous version like the p3 cA2 & cBO stepping!

Stepping 2 is the kB0 processor, stepping 3 is a kC0. There is not much difference between the Katmai b0 and c0 stepping....the only thing is a few bug fixes. No difference in terms of overclockability or speed.
