Jim - Re:<From what I hear the Coppermine .18u won't ever get much past 800MHZ which means that in this early stage of .18u maturity that 733 is pushing it...> Tench - Re:<Then its obvious that our two sources are telling us two very different stories.> It appears that Intel will release Coppermine at 1.6V (not 1.5V) for 20A gate oxide. They seem to be pushing right up to the reliability limit although I'm sure their model supports it. Based on this new information, I would predict Coppermine to reach at least 850MHz. If they made ANY device improvements since they last reported (Dec 98 IEDM) they will reach 900MHz. We should see at this year's Dec IEDM. In my experience, the Fmax responds near linearly to drive current. So, a device design optimization which increases drive current 5% at the same channel length will increase Fmax by about 5% as well. This level of optimization is entirely possible. So, 900MHz looks very probable. THE WATSONYOUTH
