This go 'round, we've got the 32nm Arrandale (which consists of the Core i5 Mobile and Core i3 Mobile) heading for the laptops and the 32nm Clarkdale chips over on the desktop front.
Core i3-5xx and Core i5-6xx machines are also slated for the early part of 2010, based on that energy-conscious Clarkdale core we've already seen, with the difference being that Turbo Boost and higher L3 cache (4MB versus 3MB) will be available on the higher numbered chips.
