Slatterz writes "LGA 1366 is Intel's first new desktop socket in four years. It uses the same ZIF design as the familiar LGA 775 architecture, but it incorporates many more contacts. These big architectural changes are backed up by some less visible advances. Until now, Intel's quad-core processors have been constructed from two dual-core dies, but now Core i7 brings together four cores on a single die. It's also Intel's first processor design to use an L3 cache, shared between all four cores."
