Third-Generation Core i7 Desktop Models
Contents
In the table below, we listed all third-generation Core i7 desktop processors, which are based on the Ivy Bridge microarchitecture. The models released so far are based on socket LGA1155 and have a dual-channel memory controller supporting 1,333 MHz and 1,600 MHz DDR3 memories. They have an integrated PCI Express 3.0 controller supporting one x16 connection, two x8 connections, one x8 connection or two x4 connections. Communication with the motherboard chipset is achieved through a DMI bus (2 GB/s each direction, listed as 5 GT/s by Intel). These models have an integrated DirectX 11 video controller running at 650 MHz with a 1.15 GHz “boost” clock, with 12 (HD 4000) processing cores. All models support three displays (previous generations support two).
The third-generation Core i7 desktop models are quad- or six-core CPUs using the Hyper-Threading technology. This means that the operating system will recognize all these CPUs as having either eight or twelve 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.
* The temperatures listed above are Tcase, which is the maximum external temperature of the CPU. On some other models, the manufacturer lists Tjunction, which is the maximum internal temperature of the CPU. The two are not comparable.
