<Note: 1.75 = GOOD (AMD) Note: 1.75 = BAD (Intel)> Paul, repeat after me. 1.75 Vcc end of life Tbird is GOOD. 1.75 Vcc baby P4 is VERY BAD. 1.XX Vcc baby Palomino is VERY GOOD. Kap

Paul, "1.75v = GOOD (AMD), 1.75v = BAD (Intel)" The reason the boost to 1.75v is a bad sign for Intel is that the 1.5 GHz P4 already dissipated 54.7w of non-worst-case power at 1.7 volts. At 1.75v, this will boost to 58 watts. At 1.7 GHz, that will boost to 66 watts. This is the same specification as the 1.2 GHz TBird, but there is a big difference. The robust TBird can zip along at 1.2 GHz even if the junction temperature reaches 95 degrees C (case temp around 90), but no P4's, even 1.3 GHz will operate above 72 degrees case temperature. A P4 1.7 GHz will require the hugest heat sinks ever seen in a PC to keep the fragile P4 from locking up and/or self destructing. And what if the 1.7 GHz P4 needs even more than 1.75 volts? And, if the P3 1 GHz and recalled 1.13 GHz are any guide, the 1.7 GHz P4 will need to keep the junction temperature even lower to reach 1.7 GHz. Want to hear my prediction? The 1.7 GHz P4 will be such a thermal problem and low yield that we will see a 1.6 GHz P4 first. Petz
