Intel has allegedly slipped information on three new processors, currently in development. Two of these fall under the existing Core i7 line, but also under a new 800 sub-series: the 2.8GHz 860, and the 2.93GHz 870. The chips use Lynnfield architecture, in this case built around four cores and eight threads.

The third CPU is one of the first Core i5 models, the 2.66Ghz 750. Aside from a lower clock speed, the model is reduced to four threads, and is thus unable to handle simultaneous multithreading. All three processors are said to have a TDP (thermal design power) rating of 95W.

Intel is also said to be working on lower-power i5 and i7 models, the former of which should run at 82W. The i7s -- expected in the first quarter of 2010 -- should include the 2.4GHz 750S and the 2.53GHz 860S.
