All the new C-Version CPU's I have seen are copper. There is no way that using a different interconnect technology could change the top of the color of a CPU core so the color difference is almost certainly related more to the fab facility than the metal interconnect technology. It's probably the use of a different final polish used before writing the label on the cores, thus if the Dresden plant started to manufacture aluminum based chips (which I seriously doubt will ever happen since they are outfitted for copper) they would still be blue. Just a little tid-bit. I am pretty sure that all new Athlons at and beyond 1GHz are copper. Copper is a better conductor than Aluminum, as you know, so is probably necessary to keep the heat level at only extremely hot rather than instant-silicon-vapor hot. Now if only they could figure out how to use Silver interconnects... _________________________________________________________________ Get your FREE download of MSN Explorer at http://explorer.msn.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
