For sure the 512k version is Tualatin, available from the link I showed you. As for the desktop 256k version, it seems as though these would also be tualatins, but are being advertised by some venders as Coppermines. I have serious reservations about that, since Tom actually tested a 256k Tualatin, and it would make sense that the .13 micron process would result in a lower core voltage, making separate lines for the Tualatin and .13 Coppermine an uneccessary expense. I now believe that venders who call the 256k version a Coppermine are seriously mistaken. Hopefully someone will clarify this.
