One thing you have to realize is that Opteron is at the beginning of its life on a new process. There may still be low-hanging fruit in terms of optimizing the design or the process, and AMD might be holding back on clocking the chip higher (because they don't have a reason to). I believe AMD has said the Opteron/Athlon 64 will reach 2.6GHz with the current 0.13um process, so if the 2GHz chip is beating a 3.2GHz P4, the 2.6GHz chip would beat a 4.2GHz P4. Of course, to get above 3.2GHz, Intel has to switch to their 90nm process, so AMD is quite clearly beating Intel on the same process. Of course, Intel is moving to a new process faster than AMD, so that has to be taken into account, and Prescott will be significantly more "efficient" than Northwood, but IMO it seems like AMD has enough headroom to at least stay even with Intel until they can switch to a newer process. Oh, of course this entire post assumes 32 bit code. 64 bit code will give the Opteron a boost (although new HT will give the Pentium a boost). -Tom
