The desktop versions of Intel's Ivy Bridge processors have most of their details outlined in full through a roadmap discovered this week. The X-Bit Labs copy shows all the chips falling under the 3000 series in the same Core i3, i5, and i7 tiers, with four cores still the maximum for non-Extreme chips. Clock speeds would have a higher baseline, starting with a 2.7GHz Core i5 (3.2GHz after Turbo Boost) and peaking at a 3.5GHz Core i7 (3.9GHz).
