Buckwheat,

Re: "So 1.8 volts, 2.1 volts, 2.2 volts .... what is the real significance of this?"

Please re-read my original post to you ... "But more importantly, the higher operating voltage will cause the K6 to be a lower speed CPU for both notebook and desktop operation as compared to Intel offerings."

Using a higher voltage for a process generation is a "no win" solution
and done by AMD because of lack of device/process expertise. Remember,
the two equation that we are trying to optimize for a process generation
are:

Power ~ CV^2f ... C=Capacitance, V=Voltage, f=Frequency
Performance ~ I/(CV) ... I=FET Idsat, C=Capacitance, V=Voltage

Increasing the voltage for a process generation is never a good idea !!

Make It So,
Yousef
