Intel plans to rename their upcoming Socket T processors to reflect a new naming convention. Remember, only the Socket 775 processors will get the new names. Without further ado:

We did not get confirmation on the 4.0GHz, 3.8GHz and 3.6GHz Processors, but there does seem to be an evident pattern emerging. One does beg to question what Intel's strategy is once/if speeds get up into the 4.6GHz range. Either this is not a very forward looking nomenclature, or Intel has some other ace up their sleeve.

The Celeron numeration seems much more conservative; there is obviously a lot more room for Intel to play with on the "3xx" series.
