First-Generation Core i7 Desktop Models

In the table below, we listed all first-generation Core i7 desktop CPU models, which are based on the Nehalem microarchitecture. Models based on the socket 1156 use dual-channel memory architecture, supporting DDR3 memories up to 1,333 MHz, while models based on the socket 1366 use triple-channel memory architecture supporting DDR3 memories up to 1,066 MHz.

Socket 1156 models also have an integrated PCI Express 2.0 controller, supporting one x16 lane, which can be split into two x8 lanes for accessing two discrete video cards. On these CPUs, communication with the motherboard chipset is achieved through a DMI bus (1 GB/s per direction). Socket 1366 models don’t have an integrated PCI Express controller, and they talk to the chipset using a QPI bus working at 2.4 GHz (4.8 GB/s) on the “regular” models or at 3.2 GHz (6.4 GB/s) on the “Extreme” models, which are listed in a separate table below.

The first-generation Core i7 desktop models are quad-core or six-core CPUs using the Hyper-Threading technology. This means that the operating system will recognize all these CPUs as having eight or 12 cores. 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.
