Constantine, I was hoping for lower voltage, and lower power consumption, but if it takes 1.65V to get higher clock speeds on desktop, I guess we have no choice. I am hoping that AMD will introduce another parallel line of low power, lower clock speed parts, PowerNow enabled, which would go to SFF and potentially blade servers. AMD could probably charge more for these (per MHz) than desktop chips. AMD is wasting away the PowerNow advantage, and it will be entirely lost when Banias is released. Joe

>>Joe, weird. My XP1600+ runs at 1.6v 24/7. I was hoping that the Tbred would be able to do at most that and maybe even 1.5. If we assume power dissipation is proportional solely to the square of the voltage, a reduction of 0.1 V from 1.85 V yields a power saving of about 11%. If we assume Athlon speed is limited by raw power dissipation alone, we get a new top speed grade of (1.733 x 1.11 = 1.92 GHz). If we are a little bit generous and call this 1933 Mhz, this means the Athlon can reach an XP rating of 2400 on the 0.13 process. Not bad, but let's hope there some other improvements or this hypothetical 2400 will not be very competitive with Intel's offerings in the second half. Of course, if Athlon gets SOI in 2H'02 and SOI accounts for a compounding 10-15% in MHz increase, then AMD should OK if Hammer is not too far delayed.
