This paper describes the second-generation Intel Core processor, a 32-nm monolithic die integrating four IA cores, a processor graphics, and a memory controller. Special attention is given to the circuit design challenges associated with this kind of integration. The paper describes the chip floor plan, the power delivery network, energy conservation techniques, the clock generation and distribution, the on-die thermal sensors, and a novel debug port.
