They have performance comparable to Opteron (within ~10%), and >very competive price... They're not even close in performance Eugene, opteron blows them away on the left and right. And you don't even need good coded software for that, which is the original excuse from intel why P4 was so slow (and still is). Prescott is still far away from running dual in shops where you can buy it. Perhaps Prescott-Xeon MP will be released in januari 2005? Of course at 3.4Ghz. You're talking about that as being a 'p4' i bet :) Even itanium blows away P4s for DIEP. To my own amazement. Note that i usually do not have time, like no one has, to wait for hours to get a PGO version of DIEP at itanium2-madison. Which shows why the whole EPIC stuff is nothing more than a failed experiment either. >Thanks, >Eugene
