Paul: FYI - AMD had to JACK UP their already high 2.2 volt Vcc to 2.4 volts just to overclock their 400 MHz parts to 450 and 475 MHZ for the K6-2. How come I knew that one was coming? Ok, I'll try this one time: Yes, AMD had to 'jack up' their voltage. But it is NOT reasonable to say that their starting voltage (2.2V) is high just because Intel's is lower. It doesn't work that way. Voltage is NOT simply a matter of how good your process is. Hell, the Alpha processors have always used extremely low voltages despite a fairly poor process. This also explains why the K7 uses 1.6V. Also, please note that POWER consumption is not solely dependent on the voltage. Both the K7 and the Alpha chips draw an incredible amount of current, but use a low core voltage. --fyodor
