Paul - Re: this whole voltage deal... We have all read the AMD ISSCC paper. We do not seem to agree on what it says, however. Let me just quote it for those who don't happen to have a copy handy: The phase-locked-loop (PLL) operates with a 2.5V supply, internally regulated down to 1.6V to satisfy .... This can be interpreted in both ways (i.e. with the PLL being the only 2.5V part and the opposite). Since I am unable to read the mind(s) of the person(s) who wrote this, I have to resort to other information. The figure on the opposite page of the same ISSCC paper (http://130.113.184.129/idiot/k7process.gif) states that the voltage is 1.6V. To me, this seems to indicate that the correct interpretation is that the PLL operates at 2.5V. Furthermore, Alpha processors run at a relatively low voltage (2.2V, with the PLL running at 5V) - again indicating (to me, at least) that the correct interpretation is that the PLL runs at 2.5V, while the functional units of the CPU run at 1.6V. --fyodor
