A leaked roadmap has revealed some details about the timeframe in which Intel will launch its new Core i3, i5 and i7 processors. Included in the upcoming launches are two low-powered "S" versions of the Core i5 750 and i7 860 Lynnfield chips, clocked at 2.4GHz and 2.53GHz (and scale up to 3.2GHz/3.46GHz). These new S chips are slated to consume only 82W of power versus 95W, while featuring 8MB of L2 cache and should appear in the first quarter of 2010.

The leak doesn't end there, it also gave a peek into the Clarkdale product line up. If it's legit, according to the leak, Intel is all set to roll out a new Clarkdale-based Pentium G6950 clocked at 2.8GHz with 3MB of L2 cache. The Core i3 530 and 540 will be introduced with frequencies of 3.06GHz and 2.93GHz, and 4MB of L2 cache.

Also included in the list for a Q1 release are a few dual-core Clarkdale Core i5 processors. The i5 650, 660/661, and 670 with clocks speeds of of 3.2-3.46GHz, 3.33-3.6GHz, and 3.46-3.73GHz - way higher than the presently available quad-core i5 750's 2.66GHz. As per the document image, all of the mentioned Clarkdale i5 chips will have a thermal envelope of 73W, except the 661, which will consume 87W.
