First-Generation Core i7 Mobile Models

The first-generation Core i7 processors targeted to laptops can use two different pin-outs, PGA988 or BGA1288, and have an integrated dual-channel DDR3 memory controller supporting 1,066 MHz or 1,366 MHz DDR3 memories. They have an integrated PCI Express 2.0 controller, supporting one device at x16 speed, and some of them have an integrated DirectX 10 video controller running at 166 MHz (18 W TDP models), 266 MHz (25 W TDP models) or 500 MHz (35 W TDP models). Communication with the motherboard chipset is achieved through a DMI bus (1 GB/s per direction).

First-generation Core i7 mobile CPUs can have two or four processing cores, supporting Hyper-Threading (HT) technology, which simulates two logical processing cores in each physical core. Therefore, they are recognized by the operating system as four- or eight-core CPUs. However, only half the cores are “real;” the other half is simulated.

TDP stands for Thermal Design Power and indicates the CPU maximum thermal dissipation, i.e., the CPU cooler must be able to dissipate at least this amount of heat.
