Prescott model numbers create confusion
I was flipping through a Tiger Direct catalog today and stumbled across a little mistake
that may become more common as Intel's new Prescott processors trickle into the market. Tiger Direct incorrectly lists Intel's Prescott Pentium 4 3.2 and 3.4GHz processors as "Extreme" chips, likely due to confusion over the "E" Intel is tacking on the end of its Prescott part numbers. A Prescott Pentium 4 3.4GHz's model number CP2-P4-34008EC, which could easily be confused with an Extreme Edition Northwood Pentium 4 3.4GHz whose model number is CP2-P4-34008EEC.
Tiger Direct's mistake is an honest one, but also easy to make; it wouldn't surprise me to see other retailers incorrectly decipher Prescott's model number. So, if you see an "Extreme" Pentium 4 whose price looks too good to be true, check the model number and cache size. You might be looking at a Prescott.
