Below you can see the Core i7 models for desktops released so far. As explained, socket 1366 models (models starting with the number "9") have an embedded triple-channel memory controller supporting DDR3 memories up to 1,066 MHz, while on socket 1156 models (models starting with the number "8")the memory controller supports dual-channel architecture and DDR3 memories up to 1,333 MHz. Socket 1156 models have an integrated PCI Express 2.0 controller supporting one x16 lane or two x8 lanes. The communication with the external world on socket 1366 models is done using a QPI bus running at 2.4 GHz (4.8 GB/s) while socket 1156 models use a DMI bus (2 GB/s).

Turbo Boost is an automatic overclocking done by the CPU when it "feels" that more processing power is needed. Here we are listing the maximum clock the CPU can achieve when this mode is enabled.

On the table below you will find all Core i7 Extreme models for desktops released so far. These models have the QPI bus running at a higher clock rate (3.2 GHz, 6.4 GB/s) and come with their clock multiplier unlocked, providing an addition overclocking option.

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.
