The chipmaker reportedly posted the date on a website for resellers that is accessible with a username and password only, according to Daily Tech.
The Intel website listed seven Penryn models with clock speeds ranging from 2GHz to 3.16GHz. Except for the 120W 3.16GHz model, all chips consume 80W of power.
A spokesperson for Intel declined to comment, adding that information posted on the reseller site is subject to non-disclosure agreements.
The company has officially stated that it plans to start production of the 45nm processor in the second half of this year, but has not yet disclosed a launch date.
Intel is expected to be the first chipmaker to launch 45nm silicon. The new Penryn is slated to outperform AMD's forthcoming Barcelona Opteron processor that starts shipping to server makers this month.
Penryn is the first chip to use so-called High-K and metal gate transistors, which allow the company to dramatically reduce power consumption. The chip is also the first to introduce the new SSE instruction set.
