Intel steps up Harpertown, Wolfdale and Core i7 920

Today, Intel announced nearly all Harpertown and Wolfdale-DP CPUs will move from the C0 stepping to E0. Excluded are X5272 and E5205 which will remain at C0. Core i7 Model 920 only will move from C0 to D0. The reasons for the change include a new halide-free packaging, as well as internal revisions allowing for lower power consumption on some models. The new steppings is also electrically and mechanically compatible for drop-in replacement, but will require BIOS updates.
