Charles - Re: " Even after taking into account the voltage bump, is it not impressive that AMD has been able to get the K6 family into the high-400 MHz range? Why? Or why not?" No. AMD has adjusted their 0.25 micron process to incorporate features of a 0.18 micron process. The 400 MHz K63 - and I assume the 400/450/475 MHz K6-2's now have a 0.18 micron (Final CD) gate length, 36 - 38 nM gate thickness (down from >40 nM) and Cobalt Silicide gates. These are "almost" 0.18 micron minimum feature devices already - so this performance is a LET DOWN - considering that AMD STILL HAD TO JACK UP THEIR SUPPLY VOLTAGES to 2.4 volts to hit Intel's 2.0 volt speed bins. Re: "What is your estimate of where AMD will begin K7 on 180nm and how far AMD can ramp its K7 on 180nm (ignore copper)? " AMD should be shipping some small volumes of 0.18 micron products by Q499 - but the performance will be "muted" since the existing 0.25 micron parts already incorporate many 0.18 micron "modules" and 500 MHz parts seem difficult to obtain. Maybe the K7 architecture will allow for some performance increases - but 700 MHz may be a reach - for the first 6 months. Paul
