<Come to think of it, maybe there is really no new stepping at all. Instead, just by raising the MIN and MAX voltages, Intel gets to pull P4's out of the dumpster and reclassify other P4's to higher speeds.> Nice research. No wonder Intel is hell bent on spending $7.5B. Got to move the dog to 130nm Cu. Kap

John: Not my bailiwick for sure, but I seem to glean the overriding gist of your analysis...The P4 may have a tougher road to hoe ahead than has been the case to date...Sure sounds like the P4 evolution may be fraught with numerous discontinuities, some of them perhaps insurmountable...Wonder if Mr. Sanders' characterization of the P4 as a "dud" might bear out to be an accurate portrayal of the P4, after all???

Petz, Re: NEW P4's USE MORE VOLTAGE AND POWER -- EVEN AT 1.5 GHZ Very interesting research -- thanks. C't found out about another potential problem with future P4s: heise.de As you already observed, the 1.7 GHz P4 takes 50.2A. However, in Intel's Design Guide (http://developer.intel.com/design/pentium4/guides/249205.htm) the voltage regulator has a maximum limit of 55.5A. I.e. that's there's only headroom for another 5A or so. So unless Intel changes the P4's process (or its design guide), a 2 GHz P4 is not possible. It would take over 60A. Andreas
